The stabilizing parachute chamber ensures that the stabilizing parachute is packed and deployed. The size of the chamber is 0.3 x 0.19 m. The base of the chamber is designed to accommodate a stabilizing parachute and part of the stabilizer. The stabilizing parachute chamber is made of nylon avisent and has a cylindrical shape. A carabiner, a fastening tape, a carabiner fastening tape, four metal rings and a tie are attached to the camera base. The carabiner is used to hook a camera with a stowed stabilizing parachute to a cable (when jumping from an airplane) or an extension cord (when jumping from a helicopter) in an airplane. Using a fastening tape, the stabilizing parachute chamber is secured to the main parachute backpack. The upper base of the chamber, after placing the dome in it, is tied with a string. At the bottom of the camera there are 4 rings sewn to secure it with the stabilizer rings.
The stabilizing parachute (pilot chute) provides a stabilized descent of the paratrooper, putting into operation the PPK-U parachute device and the main parachute. A stabilizing parachute consists of a canopy, lines, and a stabilizer. The dome, with an area of 1.5 m2, is made of nylon fabric, has the shape of a truncated cone and consists of a base and a sidewall. 8 pockets made of painted nylon fabric are sewn to the pole part of the dome base, which serves to quickly fill the dome with air. Nylon tapes are sewn onto the outer side of the base and sidewalls, reinforced by folding the fabric and tape, and additionally sewn on both sides. 16 slings are sewn to the edge of the reinforcing frame using a zigzag stitch. The slings are made of nylon cord. The free length of lines 1, 4, 5, 8, 9, 12, 13 and 16 from the canopy edge to the stabilizer loop is 0.52 m, and lines 2, 3, 6, 7, 10, 11, 14 and 15 are 0 .5 m. The different lengths of the lines are due to their distribution from the edge of the canopy to 4 stabilizer feathers. The stabilizer is made of nylon fabric and consists of four triangular “feathers” sewn in the center. Nylon tapes are sewn on the sides of each stabilizer feather. At the top of the tape they form a loop for attaching slings. At the bottom they are brought together into a thimble, with the help of which the stabilizer is attached to the link of the stabilizing parachute. One metal ring is sewn onto each feather to secure the stabilizer with the rings of the stabilizing parachute chamber.
The stabilizing parachute link is designed to connect the stabilizing parachute to the backpack during stabilization, as well as to connect the stabilizing parachute to the canopy of the main parachute at all subsequent stages of its operation. The link of the stabilizing parachute is 1.03 m long. It is made of nylon tape in 2 folds, which in the upper part end with a loop measuring 130 mm for connecting the stabilizer. At a distance of 410 mm from it, a loop of tape is sewn to connect the power cord of the PPK-U device. A guide ring for the power cord of the PPK-U device is attached to the link using a sewn-in nylon tape. The lower part of the stabilizing parachute link branches and forms 2 power bands, at the end of which metal buckles are sewn. These tapes have arrows on them to control their position when loading the double-cone lock. Jumpers made of nylon tape are sewn onto the tapes on both sides. A tape is sewn between the jumpers, which forms a loop for attaching the stabilizing parachute link to the bridles of the main parachute canopy and its chambers. The triangle formed from ribbons is covered on both sides with kerchiefs made of nylon avisent.
The main parachute chamber ensures the packing and deployment of the main parachute in a given sequence and thereby reduces the dynamic load at the moment the main parachute opens. The chamber size is 0.63 x 0.45 m, made of nylon fabric, and has the shape of a cylinder. Consists of a base, a scarf and an apron. The side of the chamber base with honeycombs for slings is reinforced with a second layer of nylon fabric. On the outside of the base, the chamber is reinforced with two nylon tapes, which, intersecting in the upper part of the base, form a bridle designed to connect the chamber with the canopy of the main parachute and the stabilizing link of the stabilizing parachute. A scarf made of nylon fabric is sewn to the base of its upper part, covering the canopy of the main parachute placed in the chamber. To tighten the upper part of the base after placement in the canopy chamber of the main parachute, a tie is passed through the fold of the upper part of the base. On the outer side of the sling, honeycombs (gazyrs) are sewn onto the base, which serve as: one middle honeycomb (gazyr) and two groups of side honeycombs (gazyrs) with loops - for laying slings; in honeycombs (gazyrs) made of rubber cord - to hold slings of tubular honeycombs (gazyrs); two pairs of removable rubber honeycombs (gazyres) - for securing the canopy of the main parachute placed in the chamber using an apron and bundles of lines. The lower part of the base ends with a sleeve, into the hem of which an elastic ring is inserted, facilitating the orderly exit of the main parachute canopy from the chamber. To cover the edge of the main parachute canopy, an apron is sewn to the bottom of the base with two pairs of metal windows and two sewn-on pockets covering bundles of lines that secure the bottom of the camera base.
Main parachute. The dome is 28-angled, with an area of 83 m2. A reinforcing frame is sewn on top of the dome. Made from panels of nylon fabric. The reinforcing frame along the edge of the dome forms 28 loops for attaching slings. In the center of the main parachute canopy, a bridle made of nylon tape is sewn to connect it with the main parachute chamber and the stabilizing link. 28 tightening tapes are sewn above the loops for attaching the lines to speed up the filling of the parachute canopy and reduce the likelihood of it getting tangled with the lines. Between the first and 28th lines there is a factory mark - the manufacturer's mark. It has the parachute number and the date of its manufacture. 28 lines made of nylon cord 9 m long are attached to the loops of the main parachute canopy. The other ends of the lines are attached to half rings, which are located at the free ends of the harness system. To make installation easier, an orange sleeve is sewn onto the 14th line.
The harness system is the connecting link between the parachutist and the parachute. Made from nylon tape with a tensile strength of 1600 kg. It consists of a main girth, which ends with two pairs of free ends: 2 front and 2 rear with metal buckles - half rings for attaching slings. The main girth is sewn from nylon tape in two folds. It also contains a manual deployment link, a pocket for the manual deployment link ring, a loop for the manual deployment link hose, a flexible hose, 2 clips for attaching a reserve parachute, a circular strap, two leg loops with two carabiners, a curved buckle for connecting the main loop to the back -shoulder girth, 2 pairs of metal buckles for attaching the backpack's adjusting straps. There are also 2 back-shoulder straps, 2 leg straps with two carabiners and two D-shaped buckles, a chest strap, a waist strap with rectangular buckles.
The parachute backpack is designed for fastening and placing in it (stacking) the main parts of the parachute (the canopy with lines and parts of the risers). It is made from nylon avisent. Consists of a double bottom, left and right valves. A stiffening frame is inserted into the bottom of the backpack. In the upper part of the backpack there are 2 windows for the passage of power tapes of the stabilizing parachute link. Two straps for buckles with jagged bridges are attached to the bottom of the backpack, with the help of which the backpack is connected to the dorso-shoulder straps; double cone lock with plate; a half ring for a rubber honeycomb, which secures the stabilizing parachute to the backpack; 2 buttons for fastening the valve of the double-cone lock; flexible hose for manual opening link; valve covering the double-cone lock; 8 nylon loops for attaching the backpack to suspension system; 2 rubber bands for pulling the backpack to the main girth of the harness; 2 scarves with metal buckles for ribbons with a carabiner for fastening the reserve parachute; 2 straps for tightening the backpack [not in D-1-5U!]; pocket for the PPK-U belay device. The left and right valves have metal rings for the passage of power tapes of the stabilizing parachute link through them. In addition, the right valve has a ring for securing the stabilizing parachute link loop with a cord (adapter) attached to it for turning on the PPK-U parachute device; a rubber honeycomb for refueling the stabilizing parachute link when the slack has been developed and mounting the camera with the stabilizing parachute on the backpack; a pocket with a safety valve for the safety cord of the PPK-U parachute device; pocket with a ribbon tie for placing and fastening the PPK-U parachute device. The factory and rack numbers of the parachute are marked on the right flap.
A double-cone lock is a mechanical device for closing the buckles of the power straps of a stabilizing parachute and holding them during the entire period of the parachutist’s stabilized descent, as well as for releasing these buckles and dropping them from the cones when the manual deployment link is pulled out or the PPK-U parachute device is activated. The double cone lock consists of a mounting plate, a body with two large cones, a bolt with two small cover cones, a large cone cover, a small cone, 2 shock absorbers, 2 power strap buckles, a spring washer, a flat washer, an 18 mm long screw, a cover screw, screw with nut and 3 screws 20 mm long.
The pull ring is included in the manual opening link and consists of a ring, a cable and a loop.

1. Parachute D-5 ser. 2
Parachute D-5 ser. 2 (airborne, fifth model, second series - Fig. 1) is intended for training and combat jumps from military transport aircraft by parachutists in equipment and with service weapons of paratroopers of all specialties.
Parachute D-5 ser. 2 allows you to jump from airplanes at flight speeds of up to 400 km/h as part of units from altitudes from 8000 m to 200 m. The rate of descent by parachute D-5 ser. 2 with a total parachutist weight of 120 kg does not exceed 5 m/s.
Parachute D-5 ser. 2 back It is put into operation by pulling out the exhaust ring. The required force does not exceed 16 kg. One or two safety devices Tisha PPK-U or AD-ZU are installed on the parachute.
Pue. I. General airborne parachute D-5 ser. 2 complete with reserve parachute 3-5
Rice. 2. Operation of the parachute D-5 ser. 2 in the air:
/ - stabilizing parachute chamber; 2
- stabilizing parachute: 3
- connecting link: 4
- chamber of the Yesiov dome; 5 - main dome; 6
- lachute pack
When performing training jumps with a parachute D-5 ser. 2 a reserve parachute of type 3-5 is used. Parachute 3-5 is put into operation if necessary. Bec parachute D-5 gray. 2, prepared for a jump, does not exceed 15 kg.
The parachute is absolutely reliable in operation and allows you to make more than 100 jumps within 12 years of its operation.
Parachute D-5 ser. 2 consists of the following parts: chambers of a stabilizing dome, a stabilizing parachute 1.5 × 2 with a connecting link, a chamber of the main canopy, a main dome of 83 m 2, a suspension system, a backpack with a double-cone lock, a pull ring with a cable, a portable bag. The parachute kit also includes: parachute equipment (main and backup), passport and consumables.
Parachute operation (Fig. 2). When separating from the aircraft, the parachutist in the fall uses his weight to activate the stabilizing parachute. The stabilizing dome camera with a carabiner remains in the aircraft on a cable. The stabilizing dome, filling with air, puts the PPK-U device into operation. During a stabilized descent, the parachute pack is closed. Usually you need to open the backpack 3 seconds after separation. After opening the double-cone lock with a parachute and a belay device, the backpack opens and the stabilizing parachute puts the main canopy into action. In this case, the slings come out first, and then the canopy itself, starting from the bottom edge and up to the top. The canopy fills and the skydiver descends at a speed of 5 m/s. The main canopy chamber and the stabilizing parachute with connecting link are lowered onto the canopy. All actions of a parachutist during a jump are performed in accordance with RVDS-75.
2. Reserve parachute 3-5
The reserve parachute 3-5 ensures the safe landing of the parachutist in the event of a complete or partial failure of the main parachute. When making jumps, parachute 3-5 is conveniently attached to the suspension system of the main parachute and is placed at the level of the skydiver’s chest in a horizontal position. Parachute 3-5 is activated by a pull ring with a cable and ensures the descent of a parachutist with a weight of 120 kg at a speed of 7 m/s. Parachute bec 5.2 kg. Reserve parachute 3-5 consists of a 50 m 2 canopy, an intermediate suspension system, a backpack, a pull ring with a cable and a carrying bag. Each parachute comes with a passport.
Operation of a reserve parachute. When the exhaust ring is pulled out, the backpack opens and the air flow moves the canopy away from the parachutist. Pockets at the top of the dome facilitate faster filling of the dome. After the canopy is lowered, the jet remains on the main parachute suspension system separately from the intermediate suspension system. In necessary cases, when
Introduced in the operation of a reserve parachute, you need to hold the canopy with your hands after opening the backpack, and then sharply throw it in the desired direction.
3. Parachute devices
When making parachute jumps, the use of parachute devices is a measure to increase the safety of jumps, and the devices themselves function as insurance devices. In all
Rice. 3. Parachute devices PPK-U-240B and AD-ZU-D-240:
1 - hose; 2 - cable; 3 - earring; 4 - flexible cord; 5 - flexible
hairpin
In such cases, the parachute must be opened by the parachutist himself. If he does not do this, then after a given time or at a given altitude the parachute will open using the device.
For the D-5 type parachute, devices of the PPK-U-240B or AD-ZU-D-240 type are currently used (Fig. 3).
Parachute device PPK-U-240B
The semi-automatic parachute combined and unified PPK-U-240B is a modification of the KAP-ZP device and also ensures deployment of the parachute pack after a given time or at a given height. It operates in a time range from 2 to 5 s, in height from 0.3 to 8 km. The device remains operational in the temperature range from +60 to -60° C and after being raised to a height of up to 35 tsh.
The technical life of the device is 750 operations for 4 years, and with 500 operations for 5 years it guarantees
The device operates completely without failure. In this case, the device must be stored and used carefully.
Device structure. The components of the device are: a body with a shutter, a clock mechanism with locking levers, an aneroid with a height adjustment mechanism and an exhaust device.
Operation of the device. Prnbor can work both in time and in height. During operation, the aneroid is temporarily switched off. To turn off the aneroid, you need to set the height higher than the height of the irrigator. For jumping with a parachute D-5 ser. 2 the altitude is set at 4000 m, and the operating time of the clock mechanism is 3 s. In order for the device to be ready for action, it must be weighed, that is, first insert a flexible pin into the shutter so that the clock mechanism is locked, and compress the springs of the traction device, pulling smoothly and with a force of about 30 kg on the cable until it clicks. A click means that the suction device has entered into connection with the clock mechanism and the clock mechanism is ready for operation. To set 3 seconds, you need to remove the incompletely flexible pin and release the clock mechanism until the hand is opposite mark 3 on the time scale. At the same time, the locking lever with the cutout will come somewhat closer to the aneroid stop. With an increase in height, the aneroid expands and its stop rises upward, but if the height of 4000 m is not reached, then the stop will not fall beyond the plane of the upper board of the device and the aneroid will not interfere with the operation of the clock mechanism. When separated from the aircraft, the flexible pin is pulled out of the shutter by a halyard and the clock mechanism begins to work due to the force of the springs of the exhaust device. After 3 seconds of operation, the pawl connecting the traction device with the clock mechanism disengages and the springs sharply move the cable inside the traction device. The cable, through the earring, will open the double-cone lock, and the parachute will open.
The height on the device must be set using the screwdriver key included with the device, and the power springs must be cocked using a stirrup or a cord threaded into the eyelet at the end of the cable.
The flexible hairpin needs to be countered with a thread in one fold with a measure of eight, tying three simple knots. The remaining ends of the nnti should be 15-20 mm long. It is prohibited to disassemble the device yourself. Information about each operation of the device must be entered in the passport.
The procedure for inspecting the PPK-U-240B device before mounting it on a parachute.
First you need to carry out an external inspection of the device. At the same time, make sure that the seals and glass are in good condition, there is no damage to the body and tube, there are no dents or bulges on the hose, there is no stuck pin in the bolt, the cable threads on the bolt are not torn, the loop is not deformed, the housing cover does not move, inside There is no dust or moisture in the device, the aneroid pin does not protrude outside for a fee. Then the operation of the clock mechanism is checked. For this it is necessary
Cock the device and make sure that the hand has moved beyond the last division of the scale; when the flexible pin in the breech moves by 5 mm, the clock mechanism does not release, even when the pin is bent 90° to the side. Following a general command, flexible pins are pulled out and the smooth operation of the clock mechanism is determined by ear. The operating time should be within 5 ± 0.7 s, and the clock mechanism works without jamming. After making sure once again that no foreign objects are visible inside the device through the glass, and the pin is not deformed, the device can be mounted on the parachute.
Parachute device AD-ZU-D
The AD-ZU-D device is a simplified version of devices of the KAP-3 n PPK-U type. It differs in that it does not have an aneroid and works only by time. Bec and the dimensions of the AD-ZU-D device are smaller than PPK-U-240B. The parts of the device's clock mechanism are the same as those of the K.AP-3 p PPK-U devices. When preparing the device, the difference is that there is no check of response in height, but the operating time of the device is checked from the 3 s mark, and the response time should be within 3 ± 0.3 s. The device is mounted, like the PPK-U-240B device.
Methodical advice
The commander of the department during training on the material part of the parachute D-5 ser. 2, training stowage, during training for putting on a parachute and attaching weapons, must first of all convince the young soldier of the high reliability of the parachute and the reliability of its operation. This can be achieved only with impeccable knowledge of the material part and a deep understanding of the purpose of each part during the operation of the parachute.
In this case, the structure of the parts of the parachute should be explained according to the deployment process, and the purpose and functions of this part should be shown by the method of sequential dissolution of the parachute laid according to all the rules. The stowed parachute is placed on the stowing table next to the parachute, extended to its full length. In this case, the method of explanation “from top to bottom” contributes to better memorization, i.e. in the sequence in which these parts come into operation when making a jump.
When explaining the operation of a parachute as a whole, attention should be paid to the relationship between the work of the parts of the parachute and the actions of the parachutist himself.
For example, if a paratrooper has completed all the necessary actions on the plane and in the air, then nothing can delay the process of opening the parachute, since the carabiner of the stabilizing parachute chamber will be hooked to the cable in the plane or to the ring of the extension cord; the carabiner pawl will not allow the carabiner to detach. a beanie from the cable, a carabiner with a camera when separating the parachutist from
The aircraft will remain on the cable, and the stabilizing parachute will enter the air flow. Failure-free inflation of the stabilizing parachute will occur because the canopy pockets and stabilizer feathers will direct the flow into the canopy in less than 0.1 s. Pulling out the pull ring will force the double-cone lock to open, and the force of the stabilizing canopy, equal to the weight of the parachutist and holding the parachutist in a comfortable position for engaging the main canopy and for the parachutist to operate in the air, will pull the canopy and the lines to its full length, thereby ensuring reliable filling of the canopy . The special design of the dome chamber completely eliminates the possibility of the dome overlapping with slings.
From here it is clearly seen that the precondition for an incident can occur only in two cases: when the carabiner is not engaged and when the pull ring is not pulled out.
Therefore, performing these two actions is mandatory for every paratrooper.
At the same time, it should be explained to young soldiers that to control the engagement of the carabiner, a releaser is appointed, who is responsible for the entire process of parachutists jumping from the plane. In case the paratrooper delays in pulling out the ring, then after set time The parachute switch will open the double-cone lock without the intervention of the parachutist.
The combination of a detailed explanation with a practical training film will ensure that every paratrooper can overcome any uncertainty or fear of skydiving.
II. PACKING HUMAN LANDING PARACHUTES 1. Stowing the main parachute
Parachute stowage D-5 ser. 2 is carried out by two people - the layer (the owner of the parachute) and the helper. For ease of control, the process of packing a parachute is divided into stages, and the stages into operations. The stages and correctness of stowing the parachute are controlled by the unit commander and the airborne forces officer.
For stowage, parachutes are concentrated in a prepared workplace specified by the unit commander. At the same time, the installation accessories necessary for quick and high-quality installation indoors, outdoors, and in the presence of wind are prepared (Fig. 4). The set of packing accessories includes: camping cloth 16X1 m; lining sheet 5.5X1.26 m; 11 metal crutches; 3 weights with sand 450x70 mm; laying fork with hook; portable bag for storing and carrying accessories.
Laying stages: I - inspection of the parachute; II - laying the dome; III- packing the canopy into the chamber and laying the lines; IV - styling
Stabilizing parachute; V - tightening the backpack, installing the device ii double-cone lock; VI - adjusting the suspension system and filling out the passport.
Rice. 4. Parachute stowage kit
Execution of stages (Fig. 5)
I t a p. Inspection of the parachute. For inspection and stowage of the parachute
must be removed from the parachute bag, place the parts of the parachute on
pull out the panel, canopy and slings to their full length. Scroll by
passport for the presence of all parts and proceed to inspection. Steam parts
The chute is inspected in the following order: stabilization chamber
raging dome; stabilizing canopy with slings; connect-
body link; main dome camera; canopy with slings; under-
spring system; backpack with flexible hose and double-cone lock;
string exhaust ring; portable bag; device PPK-U-240B
or AD-ZU-D. During inspection, it is necessary to pay attention to
the presence of all parts of the parachute, their serviceability and mutual reliability
connection.
If rips, burns, abrasions of the fabric with broken threads are detected, if there is contamination, damage to the integrity of the seams, the absence of any elements, and when inspecting metal parts - burrs, corrosion or jamming of moving parts, as well as if there is doubt about the serviceability of parts or correctness their formations must be reported to the commander of their unit and the airborne forces officer supervising the installation. After completing the inspection, insert the ring into your pocket. pass the cable into the hose.
Stage II. Laying the dome. After checking the steam readiness
shuttle to laying proceed to laying the main dome. For
This laying and helping one takes their places (laying - at the lower edge of the dome, helping - at the top of the dome).
The laying person takes the control 14th sling, put it on it
live the loop of the 15th line. With your second hand, straighten the lower edge
> place between these slings and place the middle of the edge on the laying
Dock panel. Continue laying until the factory mark. After this, transfer the unlaid half of the dome to the laid one, move the control 14th line to the right by 2-3 cm and continue laying the dome in the same order until the factory mark. When installed correctly, the factory mark on the dome should be located on the top right. Upon completion of installation, remove the weights from the dome and tuck right side dome, and then the left one across the width of the chamber and put the weights back on.
Place the camera on the dome, which helps keep the dome from moving, preventing weights from being left on the dome. After putting the camera on, trim the edge of the dome and check that it is level with the tape sewn around the perimeter of the camera.
Check that the dome is installed correctly.
To do this, the helper holds the slings from moving at the lower edge, and the laying one, taking slings 1 and 28 in his hands, walks from the lower edge of the canopy to the backpack. You need to untangle the lines by lifting the backpack up and out, grasping the lines going down inward. When laying correctly, the 1st and 28th lines should be located at the free ends of the suspension system from above and first from the inside, and on the dome - first from the top.
Stage III. Packing the canopy into the chamber and laying the lines. After checking the position of the slings, proceed to securing the camera with slings. To do this, thread the rubber honeycombs into the windows of the apron and pass the slings through them, starting from the lower honeycombs. Pass the slings into the honeycombs by 4-5 cm. After securing the chamber, they should come out of the top honeycomb on the side of the chamber with 6 gases. Do not cover the slings in the honeycombs with the camera pockets until the inspection stage is completed.
Then you need to sequentially place the dome in the chamber and tighten the cord of the upper part of the chamber. The connecting link and bridle assembly of the dome and chamber should be located on the outside. Place the slings in the gazirs. To do this, insert slings sequentially into each gasket, starting with the upper central gasket, then the upper right gasket, the upper left gasket and ending with the lower right gasket. The slings should not extend beyond the gaskets, and no noticeable slack should be allowed to form between the gaskets. 60-70 cm of sling length should remain unlaid. Do not twist the slings during installation. The formation of slack in individual (stretched during operation) slings up to 400 mm at the buckles of the free ends is allowed. After laying the lines, straighten the canopy and lines of the stabilizing parachute and be ready to check the stage. After checking, close the pockets of the sealing cells.

honeycomb Mount the parachute device.
To install an inspected and serviceable PPK-U device on a parachute, you must:
set the altitude to 4000 m;
insert the nut with the bayonet pin into the mounting-non-plate hole of the double-cone lock, located closer to the end of the plate;
insert the device body into the pocket of the backpack and tie the ribbons;
insert a flexible pin into the device, cock the device and set the time to 3 s;
secure the flexible thread pin in one fold with a measure of eight;
lock the loop connecting the halyard of the flexible pin to the ring on the valve of the backpack with a thread in two folds;
tuck the flexible pin halyard into the pocket. To finally install the double-cone lock, for this:
holding the buckles of the power straps, open the lock;
put a loop of the exhaust cable on the upper cone of the shutter
Rings, and on the lower cone of the shutter - a special gray parachute device;
lock the lock with a thread in one folded figure of eight;
lower the cable shock absorber towards the hose;
check the reliability of the connection between the special screw and the nut and whether the nut with the bayonet pin is completely aligned towards the device;
close the two-cone lock with the flap and make sure that the flap is held on the button in the fastened position.
To do this you need:
straighten the main strap;
adjust the harness according to height by moving the right shoulder girth through the jumper of the OSK-D lock body, and the left one (or both, if the OSK-D lock is pet) - through the curved shoulder buckle of the main strap;
adjust the suspension system in terms of volume by reducing or increasing the waist girth using rectangular buckles;
tighten the leg loops by moving the ribbons through the rectangular buckles;
adjust the straps of the backpack to fit the strap using special tapes and buckles.
Drop the parachute, fill out your passport. After checking the parachute in the gantry, place the parachute in the bag and seal the bag.
2. Stowing the reserve parachute
Stowing the reserve parachute is organized similarly to stowing the main parachute and consists of the following stages: I - inspection of the parachute; II - laying the dome; III - laying slings; IV - placing the canopy in the backpack and tightening the backpack; V - filling the backpack, issuing a passport.
Execution of stages
Stage I. Inspection of the reserve parachute. It is performed in the same way as inspecting the main parachute. Particular attention is paid to the serviceability of the slings and the pull ring of the strings. After inspecting all parts of the parachute, you need to insert the ring into the pocket, the cable into the flexible hose, and position the intermediate suspension system so that the strap with the coupling is to the right relative to the canopy.
Stage II. Laying the dome. Laying begins with the 12th line.
Place the 13th sling on the 12th sling, straighten the edge
between these lines The helper straightens the canvas
floor to top. Continue laying in the same order until complete
Votic mark. Having then thrown the unlaid panels onto
laid down, move the 12th sling to the right 2-3 cm and continue
laying the dome to the factory mark. Upon completion of installation,
Vodsk glue should be located at the top in the middle. Dome
fold along the width of the backpack, bending the right edge, and then the left
I howl. If necessary, use weights.
To check the correct installation of the dome, you need to take the 1st and 24th slings and make sure that at the other edges they are located on top, next to each other, and at the intermediate suspension system - on top and first on the inside on the half rings. When the slings are weak from being pulled out, bend them to the half rings.
stage. Laying slings. To attach the sling, place the backpack in honeycombs at the top of the intermediate suspension system. The valve with the ring should be located on the left, the remaining valves should be turned down, and the jumper should run along the edge of the bottom of the backpack, located further from the dome. The slings are laid using a hook, without twisting them, into the far left (from the dome) cell, and then alternately into the remaining cells. At a length of 1.4 m up to the half-rings, the slings do not fit into honeycombs. This part of the slings must be laid on the slings in a zigzag pattern across the slings laid in honeycombs.
stage. Laying the canopy and tightening the backpack. Place the canopy on the backpack so that the lower edge runs along the jumper, fold the rest of the canopy zangzag onto the backpack, preventing the canopy from “unraveling.” Holding the dome with your hand,
Ladies on the dome.
While sealing the dome due to the pressure exerted on it by the valves, put the grommet of the lower valve onto the joint of the upper valve and insert an auxiliary pin. In the same way, place the second grommet on the cone, then inserting the pin. Straighten the pockets at the poles evenly on top of the dome and tighten first the left valves (with the ring), and then the right ones, inserting the pull-out cable studs instead of the auxiliary pin. Remove the slack in the cable into the hydraulic hose to the ring.
V stage. Refilling the backpack, obtaining a passport. Refuel
Carefully close the flaps of the backpack and fasten the elastic bands. Re-
the side valves must pass through the fastening rings
backpack. After inspecting the entire parachute, fill out the
port.
3. Attaching a reserve parachute
To attach a reserve parachute you need to: - make sure that the harness is fitted correctly and all carabiners are fastened;
take a parachute;
fasten the fastening carabiners to the half-rings on the backpack;
tighten the fastening straps and tuck them under the spare straps at the bottom of the backpack;
Connect the free ends of the intermediate suspension system to the brackets on the main strap by inserting the pins into the bushings all the way and turning the pins a quarter turn until the pin ears fit into their socket.
III. CONTROLLED PARACHUTE D-5 SER. 4 AND ITS FEATURES
Parachute D-5 ser. 4 is made according to the design of the parachute D-5 ser. 2 and has the same purpose. Its main difference is that the coupling is horizontally controlled, and by means of the free ends of the floating type, the speed of horizontal movement can be additionally changed. There is no OOK-D lock on the suspension system. Additional structural elements, unlike D-5 ser. 2 are (Fig. 6):
cutouts in the dome, covered with a fishing net, one each in front and behind the dome;
two control lines;
two pairs of free ends, each prepared from one piece of tape, passing through its middle in the rectangular curved buckle of the suspension system;
ends for fixing the latter from voluntary movement
schiiii.
There are some other differences in design. Bec parachute D-5 gray. 4 for jump 17 kg.
Features of stowing the parachute D-5 ser. 4.
When preparing the parachute for stowage, you need to secure the free ends from moving by inserting the sharpies into the pockets. Laying the canopy should begin with the 13th line, place the 14th line on it and continue laying. For a right-handed dome, the factory mark should be located on the top right.
After checking the correct installation of the canopy, tuck the slack of the control lines into the rubber loops. Otherwise, D-5 ser. 4 fits similarly to the D-5 ser parachute. 2.
Rules for using a controlled dome (Fig. 6, d, e). Until the canopy is completely filled, the operation of the parachute D-5 ser. 4 does not differ from the operation of the D-5 ser parachute. 2.
After filling the canopy, the paratrooper gets the opportunity to control his canopy both horizontally and in terms of speed of movement, i.e., move forward or backward at a speed of 2.3 m/s, turn 180° in 17 s, and use glide. Landing speed with a neutral canopy and calm conditions no more than

Jumping from IL-76 with parachute D-5 or D-6. The roar of the engine, the green traffic light and the endless siren - “Go.” 501,502,503,504,505. a ring, a hole in the abyss and a dome above your head...
First, the video... landing from an Il-76, the guys met in the air... but well done...! Split seconds decide everything...
Watch the video in the source...
Now we calm down and read the article. First about parachutes, then about the IL-76, jumping from it, main features and characteristics.
Parachute D-5
Parachute D-5... Big, white, round and beautiful! The dome is made of nylon, like a 28-square... it is all stitched with tapes with a tensile strength of 70 kg - this is to withstand paratroopers when they have a taxiway with them for a jump, and all the ammunition... 28 slings with a tensile strength of 150 kg each ... after all... I remember all the performance characteristics... and the lines up to the Sky are 9 meters long.
Tactical and technical characteristics will be placed...
But you can’t throw a person into the Sky who doesn’t know how to control himself in the air... and to prevent a disorderly fall, the D-5 parachute, as well as the D-6, is equipped with an exhaust stabilizing dome... I have one at home... .. only the lines were cut off, they were needed... it’s still good... stabilizing - this means that its function is to stabilize the fall so that the parachutist is not carried away by the air flow into a disorderly fall, where the ground is everywhere: above, below, and left and right... When the parachute opens, it should go into clear sky so that the parachutist’s arms and legs do not interfere or get tangled in the lines... This is the main task of the stabilizing canopy. He comes out first, and after 5 seconds the PPK-U device is triggered to open the backpack... there is a two-cone lock on the backpack, which opens either with the device or with a ring, which the parachutist can pull before five seconds of free fall. The stabilizing parachute pulls the entire canopy out of the parachute pack...
Visualize the deployment system of the D-5 and D-6 parachutes. One person jumps, and this is how the parachute gradually opens.
Designed for training jumps from transport aircraft from heights up to 8,000 meters at speed aircraft up to 400 km/h

made of silk cord ShSh-80.
Eight valves provide quick opening of the backpack valves. backpack rubbers 9
, of which seven are single and one is double.
The length of a single backpack rubber with pendants is equal to 370 mm, and double - 385 mm. At one end, the backpack rubbers are permanently attached to the wire loops on the backpack valves.
Two scarves with buckles are sewn onto the side flaps of the backpack on the outside along the perimeter tape. 10 , to which the reserve parachute mounts are attached 13 , designed to attach it to the main parachute and to regulate the tightness of the parachute to the parachutist’s body.
The reserve parachute attachment consists of a ribbon (LRT art. 159-T) and a carabiner. The factory markings are placed on the outside of the left side valve.
Metal hinges 12 sewn on the backpack perimeter tape to fasten the double backpack rubber of the upper valve in order to prevent the pilot parachute from getting caught on the tail nut of the semi-automatic device and to protect the parachutist from being hit by the tail nut of the semi-automatic device.
On the right side flap 16 located in the device pocket 14 for placing a semi-automatic device, carabiner pocket 15 , which serves as a pocket for a substitute passport card and for stowing a carabiner of a traction rope, a tie ribbon for attaching the device, a ring 20 for securing the traction rope, hose fastening tape 21 for laying a flexible hose when jumping with manual opening of the backpack.
Safety valve 19 , which is a continuation of the right side flap, is fastened with four turnstile buttons 17 after tightening the backpack.
Safety and bottom valves have metal plates 27 to add rigidity.
Bottom of the backpack 23 on the outside it has four pairs of loops 22 for attaching the harness to the backpack, belt loops 11 for guiding backpack rubbers.
At the bottom of the backpack, on the inside, along the sides and bottom of the perimeter of the stiffening frame, pockets are sewn, left and right 24 , and valve 31 , preventing the canopy placed in the cover from blowing off from the bottom of the backpack at the moment the parachute opens and ensuring consistent pulling of the cover with the canopy placed in it.
By internal parties The backpack cord is missing from the pockets.
The pockets at the top flap of the backpack have holes 25
, under the facing of which metal rings are inserted for rigidity.
Rubber honeycombs are passed through the holes 26 , which are closed by bunches of slings. Rubber honeycombs are attached with a noose loop to a cord attached to the upper valve of the backpack near the stiffening frame. The cord and the place of attachment of the honeycomb with the cord are covered with belt loops.
