PURPOSE AND CONSTRUCTION OF PARACHUTE PARTS.

Parachute canopy(Fig. 8) is designed for the safe descent and landing of a parachutist. Dome area - 82.5 square meters. m. The shape of the dome is a regular 28-square. The dome is made of cotton fabric with anti-putrefactive impregnation. A reinforcing frame made of nylon tape is sewn onto the top of the dome. It is designed to evenly distribute the load on the dome fabric and localize gusts if they occur. There is a pole hole in the center of the dome, designed to provide a stable, swing-free descent. By crossing the reinforcing frame strips at the pole hole, a pole bridle is formed. At the lower edge of the dome, the reinforcing frame tapes form 28 loops for attaching slings. There are 25 pockets sewn between the slings on the outside of the canopy at the bottom edge to speed up the process of filling the canopy. On the canopy, to create horizontal speed, there are three slots, they are located between the lines NN 27-28; 28-1; 1-2.

Control lines are used to control the parachute (its horizontal speed). They are attached to the main lines NN 26,27, 28 and 1, 2, 3 in their lower third and end with plastic brakes on the free ends of the parachute suspension system.

The main canopy slings (28 pcs.), 8 m. 87 cm long, are made of cotton cord with a strength of 125 kg. to break. At the lower edge of the dome they are attached to the loops formed by the reinforcement frame tapes, and with the other end - to the half rings at the free ends of the suspension system.

Hanging system(Fig. 9) - is the connecting link between the parachute canopy with lines and the parachutist and serves to evenly distribute the load at the moment the parachute canopy opens. TO suspension system the backpack is mounted, and the canopy lines are attached to the free ends.

The suspension system is made of nylon tape with a strength of 1600 kg. Consists of a main circular strap (1), starting and ending with free ends (2) and passing under the parachutist’s body; two dorso-shoulder girths (3) (left and right), forming a chest bridge (4), turning into a waist girth (5); two leg loops (6).

Rice. 9

The suspension system contains:

* half rings for attaching slings (7);

* metal buckles for adjusting the system according to height and size (8);

* D-shaped buckles with carabiners for fastening the system (9);

* brackets for fastening the intermediate suspension system of the reserve parachute.

Satchel(Fig. 10) - designed for placing a canopy in a case, part of the slings and free ends of the suspension system. Made from avisent, it has an envelope-shaped shape (double bottom with a stiffening frame and four valves). Quick opening of the backpack valves is ensured by backpack rubbers.

Rice. 10

To hold the backpack valves in the closed position, a closing device is located on them, consisting of:

* cord ring;

* two cones;

* four eyelets with a sewing washer;

* one eyelet buckle.

To streamline the process of packing and opening, a pocket made of cotton fabric is sewn to the bottom of the backpack on the inside. On the outside, tapes are sewn to the bottom for attaching the suspension system.

Two scarves with buckles are sewn onto the side flaps on the outside, intended for attaching the reserve parachute backpack.

Dome cover(Fig. 11) - designed for placing a parachute canopy in it, which streamlines the deployment process and helps reduce cases of the canopy being overlapped with lines.

The cover is made of fabric (percale or nylon) of orange color, has the shape of a sleeve 5.28 m long and is worn over the entire length of the laid dome. Reinforcing tapes (1) are sewn along the entire length of the cover, which in its upper part form a bridle (2) for attaching a traction rope. In the lower part, the cover has one pair of double removable honeycombs (3) and eleven pairs of fixed honeycombs (4) for laying slings and ends with an apron (5) with two windows. Above each window there is a pocket for storing a bunch of slings. Bundles of slings, inserted into double removable honeycombs, seal the lower part of the cover and prevent the canopy from leaving the cover prematurely. The bundles of slings laid in the honeycombs are closed with a sling fuse (6), which protects them from snagging and premature blowing out of the honeycombs by the air flow.

Rice. 11

Pull rope designed to hold the backpack valves in a closed position. It has three pins at one end and a loop at the other that connects to the pull rope loop. The traction rope is pulled through a safety cover, which protects the aircraft skin from possible damage by its pins after the parachute pack is deployed.

Pull rope serves for forced opening of the parachute pack, pulling the canopy in the cover out of the pack, the slings from the honeycomb of the cover, and pulling the cover from the canopy.

It is made of nylon tape with a tensile strength of 1200 kg, 3 m long. At one end there is a carabiner with a latch designed to hook it to the cable inside the aircraft, and at the other there is a loop for attaching to the bridle of the canopy cover. At a distance of 1.4 m from this loop, a second loop is stitched, which serves to attach the exhaust cable loop.

Break line is designed to connect the bridle of the canopy to the loop of the pulling rope, holding the canopy in the case in a tense state when pulling the slings from the honeycomb, which prevents the top of the canopy from falling down to the bottom of the cover with its subsequent inversion and reduces the likelihood of it being overlapped by the slings. It is made of cotton cord ШХБ-40, 0.9 m long.

Carrying bag designed to accommodate the parachute during storage and transportation. It is rectangular in shape and has two handles for transportation. The upper base of the bag is fastened with a cord.

Passport designed to record information about the reception, transmission, operation and repair of the parachute. The passport is an integral part of the parachute. The rules for maintaining a passport are set out in the passport itself.

INTERACTION OF PARACHUTE PARTS DURING DEPLOYMENT

Let's consider the operation of a parachute when performing a jump with forced uncuffing of the backpack and pulling the cover from the canopy with a pull rope.

When the parachutist is separated from the aircraft, a traction rope attached with a carabiner to the cable in the aircraft cabin pulls the cable pins out of the locking device and releases the backpack valves, which are folded to the sides under the action of the backpack rubbers. The pulling rope is pulled out to its full length and, holding the cover attached to its loop with the dome placed in it, pulls it out from under the pocket at the bottom of the backpack. Next, the pocket is uncapped, the free ends are tensioned and the slings come out of the honeycomb of the cover. The break line is stretched, breaks and the canopy comes out of the cover. After this, the parachute canopy is filled. The traction rope with the cable and the canopy cover remain in the aircraft (Fig. 12).

Rice. 12

When descending on a filled canopy, the holes located in the rear half of the canopy in relation to the parachutist ensure horizontal movement of the parachute forward.

Laying

Stowing a parachute for a jump with forced deployment of the pack (for uncrewing)

Stowing the parachute is carried out by two people - the packer (responsible for packing) and the helper. The stages of packing the parachute are controlled by the instructor. Before stowing, the parachute should be thoroughly inspected to determine its suitability for use. Any unusable parts found should be replaced with spare parts or repaired by the organization that owns the parachute. Repair and replacement of parachute parts should be carried out in accordance with Instruction No. 008-62 for military repair of parachute equipment.

To protect the traction rope from burns, a cover is put on it 2 made of cotton tape (LHBMkr-350-230) in the form of a hollow hose. Such covers are put on the loops of the rope and on the trailed carabiner. To control the pulling rope on both sides, the carabiner has a red tape.

Lineless pilot parachute

The pilot chute is designed to pull the cover off the main canopy.

Consists of two main parts: the parachute base 1 and spring mechanism 2 .

Upper part The base of the parachute has a hemispherical shape and is made of orange nylon fabric.

The lower part of the parachute base, attached along the perimeter of the hemisphere to the upper one, also has a hemispherical shape, turning into a conical one. The hemispherical part is made of nylon mesh fabric, and the conical part is made of nylon fabric.

On the outer surface of the dome base, four nylon reinforcing tapes with a strength of 150 kg are sewn, evenly spaced along the surface in the meridional direction. A grommet is placed on the pole where the ribbons intersect 3 .

At the bottom the tapes are brought together into a thimble 7 and braided with linen thread 9.5/6. Using a thimble, the pilot chute is attached to the connecting link and the canopy cover.

Gasyr is sewn on one of the ribbons on the upper hemispherical part of the pilot chute 4 and a ribbon with a pin 5 . The pin is designed to secure the spring mechanism of the pilot chute when folded.

The spring mechanism consists of eight meridionally located spokes ending with heads, which are secured at the pole with washers. The upper washer is located under the grommet mounted on the pole of the parachute base. Between the top washer and the grommet there is a washer made of nylon resin.

The conical spring has 5.8 working turns, with 2.9 of its turns located inside the spherical spring mechanism.

The spokes of the spherical spring mechanism wrap around the upper and middle turns of the conical spring, which are connected by a limiter made of nylon cord with a strength of 120 kg, which helps maintain the spherical shape of the parachute during its operation.

At the lower base of the conical spring there is a plate on which the cone (or cable loop) is located. 6 , designed to lock the spring mechanism in a compressed state. When pinning, the cone (or cable loop) is passed through the holes of the upper and middle washer, brought out through the grommet and pinned with a pin secured to the base of the parachute. When folded, the pilot parachute is stowed in the backpack. The pin of the pilot chute is tucked into the gas cylinder.

Dome cover

The case is intended for placing the dome in it in order to streamline its implementation.

Case 4 made of orange nylon fabric, has the shape of a sleeve 5.31 m long and is worn over the entire length of the dome, folded along the panels.

Bundles of slings, inserted into double rubber (removable) honeycombs, seal the lower part of the cover and prevent the canopy from leaving the cover prematurely (two out of 11 honeycombs are allowed to break on each side).

Safety lanyard -9 designed to protect slings laid in honeycombs from snagging.

Two guides made of power tapes for inserting the frame (during installation, for more convenient fastening of the slings).

The suspension system (Fig. 11) is made of nylon tape with the strength 1600 kg(LTK-44-1600) and consists of a main strap and two shoulder straps.

The main strap is stitched from tape in two additions, the ends of which form two free ends of length 430 mm.
The main strap has two curved buckles designed to connect it to the back-shoulder straps at the top of the harness.

A pull ring pocket is sewn onto the main strap at chest level on the left side. A flexible hose is sewn above the pocket.
At the bottom, the main strap is bifurcated, the straps are sewn end-to-end and an overlay is sewn to them for more comfortable sitting in the harness during descent.

To attach the reserve parachute to the harness system, two fastening brackets with locks are built into the main strap.
The back-shoulder girths, right and left, passing through the curved buckles and windows of the main strap, form a chest bridge and, with the help of two buckles, a waist girth, providing adjustment of the suspension system according to height.

The back-shoulder girths are fastened together, forming a cross, to which the backpack is attached.

The back-shoulder girths, going down from the cross, go around the main strap below the windows for the waist girth, forming triangles with a carbine attached on the left side, and a buckle on the right.

The lower ends of the dorso-shoulder loops, passed between the main strap and bending around it in several places, form leg loops on which buckles are mounted to adjust them according to height. Three carabiners and three buckles located on the leg loops and chest strap are used to fasten the harness.

The backpack is attached to the harness, and the canopy slings are attached to the half-ring buckles of the harness.

Satchel

The backpack is designed to accommodate a canopy in a case, part of the lines and free ends of the harness system, a lineless ball parachute and a semi-automatic device.

The backpack is made of avisent A (art. 6700) and consists of the bottom of the backpack and four valves: two side, one upper and one lower.

To the top valve 1 two flexible hoses are sewn 2 , plate head 3 for attaching the hose of a semi-automatic device and a tie-tie 4 , intended for fastening the hose of a semi-automatic device. There are two windows at the base of the top flap 5 for the exit of the free ends of the suspension system.

To hold the valves in the closed position, the backpack has a locking device consisting of a cord ring 7 , two cones 8 located on the backpack valves, four eyelets with a sewing washer 29 and one eyelet buckle 28 .

Fifth eyelet 18 , installed on the right side flap between the lower and middle eyelets, is designed to fix the position of the ball lineless pilot chute inside the backpack when folded.

Cord ring 7 made of silk cord ShSh-80.
Eight backpack rubbers ensure quick opening of the backpack valves 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.

Safety valve 19 , which is a continuation of the right side flap, is fastened with four turnstile buttons 17 after tightening the backpack.

The 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.

There is a backpack cord running along the inner sides of 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.
