I. HUMAN PARACHUTS

1. Parachute D-5 ser. 2

Parachute D-5 ser. 2 (landing, fifth sample, second series - fig. 1) is intended for performing training and combat jumps from military transport aircraft by paratroopers in equipment and with service weapons of paratroopers of all specialties.

Parachute D-5 ser. 2 allows you to jump from aircraft at flight speeds up to 400 km / h as part of units from altitudes from 8000 m to 200 m. The speed of descent by parachute D-5 ser. 2 at total weight skydiver 120 kg does not exceed 5 m / s.

Parachute D-5 ser. 2 back It is put into action by pulling out the exhaust ring. The required strength does not exceed 16 kg. The parachute is equipped with one or two safety devices tisha PPK-U or AD-ZU.

Rice. 2. The work of the parachute D-5 ser. 2 in the air:

/ - camera stabilizing parachute; 2 - stabilizing parachute: 3 - connecting link: 4 - chamber of the EU dome; 5 - main dome; 6 - larashute satchel

When making training jumps with a parachute D-5 ser. 2, a type 3-5 reserve parachute is used. Parachute 3-5 is activated if necessary. Bec parachute D-5 ser. 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 during 12 years of its operation.

Parachute D-5 ser. 2 consists of the following parts: a stabilizing dome chamber, a stabilizing parachute 1.5 s 2 with a connecting link, a main dome chamber, a main dome 83 m 2, a suspension system, a backpack with a two-cone lock, an exhaust ring with a cable, figurative bitches. The parachute kit also includes: parachute equipment (main and backup), passport and consumables.

Parachute operation (Fig. 2). When separated from the aircraft, the parachutist in the fall, due to his weight, activates the stabilizing parachute. The camera of the stabilizing dome with the carabiner remains in the aircraft on a cable. The stabilizing dome, being filled with air, activates the PPK-U device. With a stabilized descent, the parachute bag is closed. Usually it is necessary to open the knapsack 3 s after separation. After opening the two-cone lock with a parachute and safety device, the knapsack opens and the stabilizing parachute activates the main dome. At the same time, the slings come out first, and then the dome itself, starting from the bottom edge and up to the top. The canopy fills up and the skydiver descends at a speed of 5 m/s. The camera of the main dome and the stabilizing parachute with a connecting link are lowered on the dome. All actions of a parachutist during a jump are performed in accordance with the RVDS-75.

2. Reserve parachute 3-5

The reserve parachute 3-5 provides a safe landing of the parachutist in case of full or partial failure of the main parachute. When making jumps, parachute 3-5 is conveniently attached to the harness of the main parachute and is placed at the level of the parachutist's chest in a horizontal position. Parachute 3-5 is put into action by an exhaust ring with a cable and provides a decrease in the parachutist with a weight of 120 kg at a speed of 7 m/s. Parachute weight 5.2 kg. Reserve parachute 3-5 consists of a 50 m 2 canopy, an intermediate suspension system, a satchel, an exhaust ring with a cable and a portable bag. Each parachute comes with a passport.

The work of the reserve parachute. When pulling out the exhaust ring, the knapsack opens and the air flow takes the dome away from the parachutist. Pockets at the top of the dome contribute to faster filling of the dome. After the canopy is filled, the pack remains on the main parachute harness separately from the intermediate harness. In necessary cases,

Introducing the reserve parachute into action, you need to hold the canopy with your hands after opening the knapsack, and then sharply throw it in the right 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 perform the function of insurance means. In all

Rice. 3. Parachute devices PPK-U-240B and AD-ZU-D-240:

1 - hose; 2 - cable; 3 - earring; 4 - flexible cord cord; 5 - flexible

hairpin

Cases of a parachute must be opened by the skydiver himself. If he does not do this, then after a given time or at a given height, the parachute will open with the help of the device.

For a parachute of the D-5 type, devices such as PPK-U-240B or AD-ZU-D-240 are currently used (Fig. 3).

Parachute device PPK-U-240B

Parachute semi-automatic combined and unified PPK-U-240B is a modification of the KAP-ZP device and also ensures the opening of the parachute pack after a specified time or at a specified height. It works in the 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 lifting it to a height of up to 35 tsh.

The technical resource of the device is 750 operations for 4 years, and with 500 operations for 5 years it guarantees -

Xia completely trouble-free operation of the device. At the same time, the prn-boron must be stored and operated with care.

Device device. The components of the device are: a case with a shutter, a clock mechanism with locking levers, an aneroid with a height adjustment mechanism and an exhaust device.

Device operation. Prnbor can work both in time and in height. During work, the aneroid is switched off temporarily. To turn off the aneroid, you need to set the height higher than the height of the burp. For a jump with a narashyutom D-5 ser. 2, the altitude is set to 4000 m, and the operating time of the clock mechanism is nl 3 s. In order for the device to be ready for action, it must be weighed, i.e., first insert a flexible pin into the shutter so that the clock mechanism is locked, and compress the springs of the exhaust device by pulling smoothly and with a force of about 30 kg on the cable to the click. A click means that the exhaust device is connected to the clockwork and the clockwork is ready for operation. To set 3 s, it is necessary, having not completely removed the flexible pin, to bleed the clock mechanism until the arrow no becomes against mark 3 on the time scale. At the same time, the lock lever with a cut-out will approach the stop of the aneroid somewhat. With the rise to a height, the aneroid expands and its stop rises, but if the height of 4000 m is not reached, then the stop will not fall out of 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 the halyard and the clock mechanism starts working due to the force of the springs of the exhaust device. After 3 s of work, the pawl that connects the exhaust device with the clockwork, disengages and the springs abruptly move the cable inside the exhaust device. The cable through the earring will open the two-cone lock, and the parachute will open.

The height on the device must be set using a screwdriver wrench from the device kit, and the power springs must be cocked using a stirrup or a cord threaded into an earring at the end of the cable.

A flexible hairpin needs to be countered with a thread in one addition with an eight-measure, tying three simple knots. The remaining ends of the thread should be 15-20 mm long. It is forbidden to disassemble the device on your own. Information about each operation of the device must be entered in the passport.

The order of inspection of the device PPK-U-240B before mounting on a parachute.

First you need to make an external inspection of the device. At the same time, make sure that the seals and glasses are in good order, there is no damage to the body and tube, there are no dents or swellings on the hose, there is no stuck pin in the gate, the threads of the cable and the gunk are not broken, the loop is not deformed, the cover of the body does not move, inside the device is free of dust and moisture, the aneroid pin does not protrude outside the board. After that, the work of the watch mechanism is checked, For this you need

Cock the device and make sure that the arrow has gone beyond the last division of the scale, when the flexible pin moves in the shutter by 5 mm, the clock mechanism does not bleed, also when the pin is bent 90 ° to the side. On a general command, flexible pins are pulled out and the smoothness 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 a parachute.

Parachute device AD-ZU-D

The AD-ZU-D device is a simplified version of the KAP-3 and PPK-U devices. It differs in that it does not have an aneroid and works only on time. Bec and dimensions of the device AD-ZU-D are smaller than PPK-U-240B. The details of the clock mechanism of the device are the same as the details of the K.AP-3 and PPK-U devices. When preparing the device, the difference lies in the fact that there is no test for operation in height, and the operation time of the device is checked from the mark of 3 s, while the operation time must be within 3 ± 0.3 s. The device is mounted, as well as the PPK-U-240B device.

Methodological advice

Squad commander during training on the material part of the parachute D-5 ser. 2, training packing, in training for putting on a parachute and attaching weapons, he 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 an impeccable knowledge of the material part and a deep understanding of the purpose of each part in the process of parachute operation.

At the same time, the device of the parts of the parachute should be explained according to the opening process, and the purpose and functions of this part should be shown by the method of sequential dissolution of the parachute laid in accordance with all the rules. The stowed parachute is placed on the stowage table next to the parachute extended to its full length. Better memorization at the same time, the “top-down” method of explanation contributes, that is, in the sequence in which these parts come into operation when making a jump.

When explaining the operation of the 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 performed 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 camera of the stabilizing parachute will be hooked to the cable in the plane or to the extension ring, the carabiner dog will not allow the carabiner to detach. bina from the cable, a carbine with a camera when separating a paratrooper from

The aircraft will remain on the line, and the stabilizing parachute will enter the air stream. Trouble-free filling 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 paratrooper in a comfortable position for the main canopy to start working and for the parachutist to operate in the air, will stretch the canopy and lines to its full length, thus ensuring reliable filling of the canopy . The special arrangement of the dome chamber completely eliminates the possibility of the dome overlapping with slings.

From this it is clearly seen that the prerequisite for an incident can be only in two cases: when the carabiner is not hooked and when the pull ring is not pulled out.

Therefore, the implementation of 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 carbine, a release officer is appointed, who is responsible for the entire process of paratroopers jumping from the aircraft. In case the skydiver delays in pulling the ring, after a set time, the parachute jumper will open the two-cone lock without the intervention of the paratrooper.

The combination of a detailed explanation with a practical demonstration of a training film will ensure that every paratrooper overcomes the uncertainty or fear of parachuting.

II. LAYING HUMAN PARACHUTES 1. Laying the main parachute

Parachute stowage D-5 ser. 2 produce two people - laying down (the owner of the parachute) and helping. For the convenience of control, the process of laying a parachute is divided into stages, and the stages are divided into operations. The stages and correctness of parachute packing are controlled by the unit commander and the VDS officer.

For packing, parachutes are concentrated at a prepared workplace indicated by the unit commander. At the same time, laying accessories are being prepared that are necessary for fast and high-quality laying indoors, outdoors, in the presence of wind (Fig. 4). The set of laying accessories includes: 16X1 m; lining canvas-beggar 5.5X1.26 m; 11 metal crutches; 3 weights with sand 450x70 mm; laying fork with a hook; portable bag for storing and carrying accessories.

Stages of laying: I - inspection of the parachute; II - laying the dome; III-packing the dome into the chamber and laying the slings; IV - laying

stabilizing parachute; V - tightening the knapsack, installation of a device ii of a two-cone lock; VI - fitting the suspension system and filling out the passport.

Rice. 4. Parachute stowage kit

Execution of stages (Fig. 5)

I e t a p. Inspection of the parachute. For inspection and stowage of the parachute
must be removed from the transfer bag, place parts of the parachute on
pull the cloth, dome and slings to their full length. Turn on
passport the presence of all parts and proceed to the inspection. Steam parts
the chute are inspected in the following order: the stabilization chamber
dome; stabilizing dome with straps; connect-
body link; main dome chamber; dome with slings; under-
spring system; backpack with flexible hose and two-cone lock;
exhaust ring with strosos; portable bag; device PPK-U-240B
or AD-ZU-D. During inspection, attention should be paid to
availability of all parts of the parachute, their serviceability and reliability of mutual
leg connection.

If tears, burns, abrasions of the fabric with broken threads are detected, if the seams are dirty, if the integrity of the seams is broken, if any elements are missing, and when examining metal parts - burrs, corrosion or seizing of moving parts, and also if there is doubt about the serviceability of parts or the correctness their connections must be reported to the commander of your unit and the VDS officer who controls the laying. After completing the inspection, insert the ring into your pocket. a cable through the hose.

II stage. Dome lining. After checking the readiness of steam
chute for laying, proceed with laying the main dome. For

This laying down and helping to take their places (laying down - y the lower edge of the dome, helping - y the top of the ku-floor).

Laying take the control 14th line, put on it
live loop of the 15th sling. With the second hand, straighten the lower edge
> ku between these slings and put the middle of the edge on the

Dock cloth. Continue laying to the factory mark. After that, 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 to the factory stamp. When installed correctly, the factory stamp on the dome should be located at the top right. At the end of the laying, remove the weights from the dome, tuck the right side of the dome, and then the left along the width of the chamber and put the weights again.

Put the camera on the dome, while helping to keep the dome from moving, preventing weights from being left on the dome. After putting on the camera, trim the edge of the dome and check that it is located at the level of the tape sewn around the perimeter of the camera.

Check that the dome is installed correctly.

To do this, the helper keeps the slings from shifting y of the lower edge, and the laying man, taking the 1st and 28th slings in his hands, passes from the lower edge of the dome to the knapsack. It is necessary to unravel the slings by lifting the knapsack up outward, grasping the slings going down inside. When laying the lines 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 above.

III stage. Packing the dome into the camera and laying the lines. After checking the position of the slings, proceed to the check of the camera with slings. To do this, pass rubber honeycombs through the apron windows and pass slings through them, starting from the lower honeycombs. Pass the slings into the combs by 4-5 cm. After the chamber is checked, they should exit the upper comb on the side of the chamber with 6 gazyrs. Until the end of the check of the slings in the combs, do not close the chambers with pockets.

Then you need to sequentially put the dome into the chamber and tighten the cord of the upper part of the chamber. The link and bridle assembly of the dome and camera must be located outside. Lay the slings in the gazyri. To do this, the laying insert sequentially insert the slings into each gazyr, starting with the upper central gazyr, then the upper right gazyr, the upper left and ending with the lower right gazyr. The slings should not go beyond the limits of the gazyry, and between the gazyry should not allow the formation of a noticeable slack. 60-70 cm of the length of the slings should remain unstowed. During laying, the lines must not be twisted. The formation of slack in individual (stretched during operation) lines up to 400 mm is allowed for the buckles of the free ends. After laying the lines, straighten the canopy and lines of the stabilizing parachute and be ready for the stage check. After checking, close the pockets of the checking combs.

To mount an inspected and serviceable PPK-U device on a parachute, you need:

set the altitude to 4000 m;

insert a nut with a bayonet pin into the mounting hole of the two-cone lock plate located closer to the end of the plate;

insert the body of the device into the pocket of the satchel and tie the ribbons;

insert a flexible pin into the device, cock the device and set the time to 3 s;
lock the flexible hairpin thread in one addition with a measure-eight;
lock the loop of connecting the halyard of the flexible hairpin to the ring on the valve of the knapsack of the thread in two additions;

tuck the halyard of the flexible hairpin into the pocket. Mount the final two-cone lock, for this:
holding the buckles with power ribbons, open the lock;
put on the upper cone of the shutter a loop of the exhaust cable

Rings, and on the lower shutter cone - special gray parachute device;

lock the lock with a thread in one folded figure eight;
lower the cable shock absorber to the hose;
check the reliability of the connection of the special screw and the nut and whether the nut with the bayonet pin is completely driven towards the device;
close the two-cone lock with a flap and make sure that the flap is held on the button in the buttoned position.

VI stage. Fitting the suspension system and filling out the passport. Adjustment of the suspension system is carried out without connecting a spare chute.

For this you need:

straighten the main strap;
adjust the suspension system in 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 not) through the shoulder curved buckle of the main strap;
adjust the suspension system in terms of volume by reducing or increasing the waist girth using rectangular buckles;
podp_at leg girths moved by ribbons through rectangular buckles;
adjust the straps of the backpack pull-up with the help of special tapes and buckles.

For the final adjustment of the harness, it is necessary to put on a parachute, fasten the carabiners, take position before the jump, conditionally pull out the ring and make sure that the harness fits the parachutist tightly and at the same time does not restrict his movements.

Take off your parachute, fill out your passport. After checking the parachute in the goats, place the parachute in the bag and seal the bag.

2. Stowing a reserve parachute

The packing of the reserve parachute is organized similarly to the packing of the main parachute and consists of the following stages: I - inspection of the parachute; II - laying the dome; III - laying lines; IV - laying the dome in the knapsack and tightening the knapsack; V - refueling a satchel, issuing a passport.

Execution of stages

I stage. Inspection of the reserve parachute. It is performed in the same way as the inspection of the main parachute. Particular attention is drawn to the serviceability of the slings and the traction ring. After examining all parts of the parachute, you need to insert the ring into the pocket, and the cable into the flexible hose, and position the intermediate suspension system so that the strap with the clutch is to the right of the canopy.

II stage. Dome lining. Start laying from the 12th line.
On the 12th line, lay the 13th line, straighten the edge
between these straps. The helper straightens the cloth
floor to top. Continue laying in the same order until
water mark. Throwing then unlaid panels on
laid, move the 12th line to the right by 2-3 cm and continue
laying the dome to the factory mark. At the end of the laying
water glue.mo should be located at the top in the middle. Dome
fold across the width of the satchel, bending the right edge, and then le-
wow. If necessary, change weights.

To check the correctness of the laying of the dome, you need to take the 1st and 24th lines and make sure that they are located on the top and next to the middle edges, and on the top and first on the inside on the half rings. Slabnnu from the hood to drive the slings to the half rings.

stage. Sling laying. For laying the sling, it is necessary to put the satchel with honeycombs on top of the intermediate hanging system. The valve with the ring should be located on the left, the rest of the valves are tucked down, and the jumper should pass along the edge of the bottom of the knapsack, located farther from the dome. The slings are laid with a hook, without twisting them, into the left farthest (from the dome) cell, and then alternately into the remaining cells. At a length of 1.4 m to the half-rings, the slings do not fit into the honeycomb. This part of the lines must be laid on the lines in a zigzag pattern across the lines laid in the honeycomb.
stage. Laying the dome vranets and tightening the knapsack. Put the dome on the knapsack so that the lower edge runs along the lintel, fold the rest of the dome in a zig-zag manner onto the knapsack, preventing the dome from “scattering”. Holding the dome with your hand,

straighten the valves of the knapsack and put the upper and lower valves

Lords on the dome.

Seal the dome by pressing on it with valves, put the grommet of the lower valve on the cous of the upper valve and insert the auxiliary pin. Similarly, put the second eyelet on the cone, then inserting the hairpin. Spread the pockets of the y pole part evenly on top of the dome and tighten first the left valve (with ring), and then the right one, inserting the exhaust cable studs instead of the auxiliary studs. Remove the cable slack in the gpb-cue hose to the ring.

V stage. Refueling a satchel, registration of a passport. Refuel
carefully lapels of the valves and fasten the knapsack elastic bands. Re-
side flaps must pass through the fastening rings
knapsack. After examining the entire parachute, fill the pass
port.

3. Attaching a reserve parachute

To attach a reserve parachute, you must: - make sure that the harness is fitted correctly and all carabiners are fastened;

take a parachute;
fasten the fastening carabiners for the half rings on the knapsack;
tighten the fastening straps and tuck them under the grooves of the spare at the bottom of the knapsack;
connect the free ends of the intermediate suspension system to the brackets on the main strap, inserting the fingers into the bushings to the end and turning the fingers a quarter of a turn until the ears of the finger fall into their nest.

Disconnect the reserve parachute in reverse order.

III. CONTROL PARACHUTE D-5 ser. 4 AND ITS FEATURES

Parachute D-5 ser. 4 is made according to the tiiu of the parachute D-5 ser. 2 and has the same purpose. Its main difference is that the ku-yul is made horizontally controlled, and by means of the free ends of the floating type, you can additionally change the speed of horizontal movement. There is no OOK-D lock on the suspension system either. Additional structural elements, unlike D-5 ser. 2 are (Fig. 6) :

cutouts in the dome, closed 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 a rectangular curved buckle of the suspension system;

- two scarps with cords and two free pockets
ends to fix the last one from a random change
scheeia.

There are some other differences in the design. Bec parachute D-5 ser. 4 for jump 17 kg.

Features of laying the parachute D-5 ser. four.

When preparing a parachute for packing, you need to fix the free ends from moving by inserting sharps into pockets. Laying the dome should begin with the 13th sling, and then lay the 14th sling and continue laying. For a right-handed dome, the factory stamp should be located at the top right.

After checking the correct laying of the canopy, tuck the slack in the control lines into the rubber loops. The rest of the D-5 ser. 4 is stowed similarly to the parachute D-5 ser. 2.

Rules for using a controlled dome (Fig. 6, d, e). Until the full filling of the dome, the operation of the parachute D-5 ser. 4 does not differ from the operation of the D-5 parachute ser. 2.

After filling the canopy, the parachutist gets the opportunity to control his canopy both in terms of the horizon and the speed of movement, i.e. move forward or backward at a speed of 2.3 m / s, turn 180 ° in 17 s, apply glide. Landing speed with neutral canopy and calm, no more

The slings are made of kapron cord. The length of 1, 4, 5, 8, 9, 12, 13 and 16 lines in a free state from the edge of the dome to the stabilizer loop is 0.52 m, and 2, 3, 6, 7, 10, 11, 14 and 15 lines - 0 .5 m. The different lengths of the lines are due to their spacing from the edge of the dome to 4 stabilizer feathers. The stabilizer is made of nylon fabric and consists of four triangular "feathers" sewn in the center. Nylon ribbons are sewn on the sides of each stabilizer feather. At the top of the tape form a loop for attaching slings. At the bottom, they are brought into a thimble, with the help of which the stabilizer is attached to the link of the stabilizing parachute. One metal ring is sewn on each feather for locking 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 main parachute canopy 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 additions, which in the upper part end with a loop of 130 mm in size for attaching the stabilizer. At a distance of 410 mm from it, a loop of tape was sewn to connect the power cord for the PPK-U device. A guide ring for the power cord for the PPK-U device is attached to the link using a sewn-in nylon tape. The lower part of the link of the stabilizing parachute branches out and forms 2 power bands, at the end of which metal buckles are sewn. Arrows are applied to these tapes to control their position when loading a two-cone lock. Jumpers made of nylon tape are sewn on the ribbons 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 closed on both sides with kerchiefs made of nylon advice.
The main parachute chamber ensures the packing and deployment of the main parachute in a predetermined sequence, thereby reducing the dynamic load at the moment of opening the main parachute. The size of the chamber is 0.63 x 0.45 m, it is made of nylon fabric and has the shape of a cylinder. Consists of a base, a scarf and an apron. The side of the base of the camera with honeycombs for lines is reinforced with a second layer of nylon fabric. On the outer side of the base, the chamber is reinforced with two nylon ribbons, which in the upper part of the base, intersecting, form a bridle designed to connect the chamber with the main parachute canopy 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 dome of the main parachute laid in the chamber. To tighten the upper part of the base after laying the main parachute into the canopy chamber, a tie was passed through the hem of the upper part of the base. From the outer side of the sling, honeycombs (gasyri) are sewn onto the base, which serve as: one middle honeycomb (gazyr) and two groups of side honeycombs (gazyri) with loops - for laying slings; in honeycombs (gazyri) from a rubber cord - to hold slings of tubular honeycombs (gazyri); two pairs of removable rubber honeycombs (gasers) - for checking with the help of an apron and bundles of lines of the canopy of the main parachute, laid in the chamber. The lower part of the base ends with a sleeve, into the hem of which an elastic ring is inserted, which facilitates the orderly exit of the main parachute canopy from the chamber. To cover the edge of the canopy of the main parachute, an apron with two pairs of metal windows and two sewn pockets covering the bundles of lines that fasten the lower part of the camera base is sewn to the bottom of the base.
main parachute. The dome is 28-coal, with an area of 83 m2. A reinforcing frame is sewn on top of the dome. Made from nylon fabric. The reinforcing frame along the edge of the dome forms 28 loops for attaching lines. In the center of the dome of the main parachute, to connect it with the chamber of the main parachute and the stabilizing link, a bridle made of nylon tape is sewn. Above the loops for attaching lines, 28 tightening tapes are sewn to speed up the filling of the parachute canopy and reduce the likelihood of it being overwhelmed by lines. Between the first and 28th lines there is a factory mark - the brand of the manufacturer. It has the number of the parachute and the date of its manufacture. 28 nylon lines 9 m long are attached to the loops of the main parachute canopy. The other ends of the lines are attached to the half rings, which are located at the free ends of the harness. To facilitate laying on the 14th line, an orange muff is sewn on.
The suspension system is the connecting link of the skydiver with the parachute. Made of 1600 kg tensile nylon tape. It consists of the main girth, which ends with two pairs of free ends: 2 front and 2 back with metal buckles - half rings for attaching slings. The main girth is sewn from nylon tape in two additions. It also contains a manual release link, a pocket for the manual release link ring, a loop for the manual release link hose, a flexible hose, 2 shackles for attaching a reserve parachute, a circular webbing, two leg loops with two carabiners, a curved buckle for connecting the main harness to the back -shoulder girth, 2 pairs of metal buckles for attaching the adjusting straps of the backpack. There are also 2 back-shoulder loops, 2 leg loops with two carabiners and two D-shaped buckles, a chest bridge, a waist band with rectangular buckles.
The parachute backpack is designed for fastening and placing in it (laying) the main parts of the parachute (dome with lines and part of the free ends). It is made from kapron avisent. Consists of a double bottom, left and right valves. A rigidity frame is inserted into the bottom of the satchel. In the upper part of the knapsack there are 2 windows for the passage of power bands of the stabilizing parachute link. Two straps for buckles with serrated bridges are attached to the bottom of the knapsack, with the help of which the knapsack is connected to the back and shoulder girths; two-cone lock with a plate; a half ring for a rubber honeycomb, which secures the stabilizing parachute to the satchel; 2 buttons for fastening the valve of the two-cone lock; flexible hose link manual opening; valve covering the two-cone lock; 8 nylon loops for attaching the backpack to the suspension system; 2 rubber bands for pulling the backpack to the main girth of the harness; 2 scarves with metal buckles for webbing with a carabiner for attaching a reserve parachute; 2 belts for pulling up the knapsack [not in D-1-5U!]; pocket for safety device PPK-U. The left and right valves have metal rings for the power bands of the stabilizing parachute link to pass through them. In addition, the right valve has a ring for locking the stabilizing parachute link loop with a cord (adapter) attached to it to turn on the PPK-U parachute device; a rubber honeycomb for filling the link of the stabilizing parachute with the developed slack and mounting the camera with the stabilizing parachute on the knapsack; a pocket with a safety valve for the cord of the safety activation of the PPK-U parachute device; a pocket with a tie of ribbons for placing and fastening a PPK-U parachute device. On the right valve, the factory and rack numbers of the parachute are applied.

A two-cone lock is a mechanical device for closing the buckles of the power tapes of a stabilizing parachute and holding them during the entire period of a stabilized descent of a parachutist, as well as for releasing these buckles and dropping them from the cones when pulling out the manual opening link or triggering the PPK-U parachute device. The double cone lock consists of a mounting plate, a body with two large cones, a lock with two small cones of a cover, a cover of a large cone, a small cone, 2 shock absorbers, 2 power band buckles, a spring washer, a flat washer, a screw 18 mm long, a cover screw, screws with a nut and 3 screws 20 mm long.
