Description

Application area

The invention relates to parachute technology and can be used by paragliders flying off the mountain slopes, and by firms specializing in the manufacture of equipment for paragliders.

State of the art

The prior art [1], which describes the device parachute paraglider. The disadvantage of this solution is the long connecting link (5) in figure 1 with a stud. Such a long link increases the pulling time of the canopy. The prior art [2], which describes the advantages of introducing a parachute rocket in comparison with a ballistic (squib). The disadvantage of the solution is that when you enter a parachute rescue parachute (SP) with a rocket, there is a possibility of injury to a flying pilot nearby or falling into his wing or slings. For competitions, especially when processing heat flows, flights can take place in a fairly dense formation. In addition, in the presence of rotation, for a more reliable operation of the joint venture, it is recommended to throw it in the direction of rotation. A rocket can fly only in one predetermined direction.

Also, spontaneous operation of the joint venture at the start is not ruled out, because a paraglider in a put on suspension system can walk along the launch line, sit on a slope, around it there can be helpers (interfering) people or instructors. An ordinary joint venture is uncut and drops out of the container. The rocket will fly in an unknown direction. Also, this joint venture system is cumbersome and complex.

Known [3] for the paraglider's parachute complex, containing a paraglider, a suspension system, paraglider locks and a rescue parachute in a knapsack, characterized in that the checks of the paraglider lock locks are attached to the free ends of the rescue parachute, and the lengths of the structural elements are selected from the condition l + m + r <s

where l is the length of the connection connecting the lock lock of the compartment with the free end of the rescue parachute;

m is the distance between the lock and the attachment point of the free end of the rescue parachute;

r is the working stroke of extracting checks from the lock;

s is the distance from the place of attachment of the checks to the free end of the rescue parachute to the place of attachment of the free end to the suspension system.

The complex contains a paraglider, a suspension system, locks of the separation of the paraglider and a rescue parachute in the satchel. The essence of the invention lies in the fact that the lock locks of the paraglider are attached to the free ends of the rescue parachute, so the paraglider is automatically disconnected when the rescue parachute is filled. In this case, loss of altitude due to uncontrolled descent is practically eliminated when used as a rescue planning guided parachute. The reliability of the complex increases due to the reduction of the actions of the paraglider when folding the paraglider to one thing - the inclusion of a rescue parachute.

This patent describes the use of a single-shell gliding parachute as a parachute rescue parachute (SP). The use of a gliding parachute is possible only with the unhitching of the main canopy of the parachute or paraglider. Therefore, in this application, the emphasis is on the uncoupling order, when the failed wing of the paraglider is unhooked by a device operating from the free ends of the inserted rescue parachute, which really increases safety.

The disadvantage of this device (input circuit) is the fundamental decision to use a planning parachute as a rescue and, if necessary, disconnect the wing of the paraglider.

The detachment of the main dome before entering the emergency (rescue for paragliders) is dictated by the principle of “reserve in the clear sky”. Because in the case of an unconnected dome, there is a probability, confirmed in practice, when a spare dome is entered to overlap it (entanglement) with the failed main one. Which is especially common if the failure of the main dome is accompanied by rotation. Therefore, by changing the input order - SP, and then disconnecting the main one, the likelihood of a joint venture uptime is reduced.

The use of a planning parachute as a rescue for paragliders is not always justified, especially when flying at low altitude along the slopes. The reserve of height after the introduction of the SP may not be enough to carry out the required maneuver. The presence of a horizontal component in the planning joint venture, especially when landing on the countercliff, increases the likelihood of injury to the pilot. Therefore, such joint ventures did not receive distribution.

Additional devices that disconnect the free ends do not exclude accidental operation and reduce the likelihood of uptime.

The closest analogue is the existing parachute rescue parachute (SP) [4, 5, 6], is located in a separate chest container or in a container integrated in the suspension system, and serves to save lives in “special” cases, for example, in case of massive and non-restored addition of a paraglider. As a rule, the paraglider fights for the survivability of the paraglider and uses the SP as a last resort and at extremely low altitudes (less than 100 m). For this reason, the speed and reliability of the application of the joint venture are vital.

In the event of a special situation, the paraglider pilot takes the handle (2) of the rescue parachute, pulls it out of the container (1), swings it and throws the SP to the side. The rescue parachute is put into the chamber, which is marked with a bundle of SP lines (see Figure 1), threaded through an elastic loop (3) (rubber cord). After the slack of the SP line (4) is selected (approximately 1-1.5 m), the discarded chamber is uncut, the camera opens and releases the SP placed in it. The dome of the parachute, once in the stream of air, begins to fill.

The disadvantage of such a traditional laying pattern, when the parachute in the chamber is caged with a bundle of slings threaded through an elastic rubber loop (3), is the relative great effort (1-2 kg) of envelope stripping, comparable to the weight of the joint venture (about 2 kg). There were cases when the kinetic energy of the discarded chamber with the parachute laid turned out to be insufficient for its stripping. The high-pressure air flow is also not enough, because with a partially working wing of a paraglider, the vertical descent speed can be on the order of 8-12 m / s. In this case, the camera with a parachute falls next to the pilot, remaining unchecked.

In addition, the stripping force (along with it and the reliability of operation) depends on the thickness of the beam lines, the occurrence of random nodes on them, the length and elasticity of the rubber loop, which can vary with the service life, temperature and humidity. Another drawback is the impossibility of packing the joint venture as tightly as possible in an envelope (otherwise, the stripping force becomes inapplicably large). "Loose laying" increases the laying volume of the joint venture, the distance from the center of gravity of the joint venture to the handle of the envelope, which in turn increases the swing time.

The aim of this invention is to eliminate the disadvantages inherent in known analogues.

The technical result of the claimed invention is to reduce the efforts of the razchekovka cameras, increasing the reliability of operation, providing the most tight packaging rescue parachute (SP) in an envelope, reduces the time of the swing.

Brief Description of the Drawings

Figure 1 shows the well-known [4, 5, 6] principle of laying a joint venture, where 1 is a joint venture container, 2 is a joint vent handle, 3 is an elastic loop, 4 are joint vent lines.

Figure 2 shows a method of laying a joint venture with a check with a hairpin, where 5 is a rigid textile loop, 6 is a hairpin, 7 is a connecting halyard 1-1.5 m long.

Figure 3 shows a method of laying a joint venture in a beam-encapsulated sling chamber, where 8 is a protective cover, 9 is an elastic tape.

The implementation of the invention

The claimed technical result is achieved due to the fact that the method of introducing a rescue parachute, characterized by placing the rescue parachute (SP) of the paraglider in a caged chamber in a separate chest container (1) or in a container built into the suspension system of the SP, and during use the parachute is pulled out by the handle (2) rescue from the container, swing and throw the joint venture to the side, and after the slack is selected (4), the discarded camera is uncut, the camera swings open and releases The joint venture in it into the air stream, where it is filled, differs in that the jointing of the joint venture is performed with a metal pin (6) threaded through a rigid textile loop (5) (see Figure 2). In this case, the connecting link between the pin (6) and the suspension system must be lengthened due to the halyard (7) by 1-1.5 m (for the possibility of swinging the envelope of the joint venture by the paraglider pilot). The presence of such a link slightly increases the time of the SP pull (about 0.1-1 sec) and, accordingly, the filling of the parachute. All this leads to a slight increase in the minimum safe altitude of the rescue parachute system.

To eliminate this drawback, another variant of the method is proposed (see FIG. 3), which provides that the method of introducing a rescue parachute, characterized by the placement of a rescue parachute (SP) paraglider in a beam-encapsulated sling chamber in a separate chest container (1) or in a container, integrated into the suspension system of the joint venture, and in the process of use, the parachute is pulled out by the handle (2) of the rescue gear from the container, swinging and throwing the joint vent to the side, and after the slack of the sling is selected (4), dropped to measure raschekovyvaetsya camera swings open and release the stowed therein SP in the air flow where it is filled, characterized in that for locking SP operate a pin (6) is sewn on the end of a protective cover (8) which is put on top of the sling beam (4) of PO. The method may differ in that an elastic tape (9) is sewn around the envelope so that it constantly maintains the tension on the loop of the notch.

A protective cover (8) is necessary for a swing length of 1-1.5 m or more (Figure 3). At the same time, the length of the lines does not increase and it remains possible to pinch the parachute chamber with a hairpin. After filling the canopy of the parachute under the influence of the load, the cover descends to the base of the lines and does not interfere with the normal operation of the parachute system. In addition, the cover protects the lines from accidentally snagging on equipment or equipment while pulling the parachute.

An elastic tape (9) sewn around the envelope serves to maintain constant tension on the loop of the notch, which prevents the stud from accidentally slipping out during a long period of non-re-laying and caking of the joint venture inside the envelope. In general, pinning with a metal pin reduces the chiselling effort of the chamber. Also, both variants of the claimed method provide the most dense packing of the joint venture in the envelope, which reduces the swing time.
