Description

The utility model relates to the field of aviation, namely to airfield brake systems for braking aircraft.

The famous Aerofinisher (https://ru.wikipedia.org/wiki/Aerofinisher. 10.29.2017) is a device consisting of a special thick steel cable stretched across the landing deck of an aircraft carrier, the ends of which are wound on brake drums placed under the deck, equipped with powerful hydraulic brakes that dissipate the kinetic energy of the landing aircraft, so that landing mileage can be reduced to the size of the landing deck.

The disadvantage of this device is that due to the requirement of a hook (the plane during landing is hooked to the cable with a special hook - the hook released before landing), the aerofinisher is not universal and can only be used to brake specially designed or modified aircraft.

The ATU-3 brake installation is known ((https://ru.wikipedia.org/wiki/Aerofinisher. 10/29/2017), which consists of a brake cable stretched across the runway connected to the cable tossing mechanism.

The disadvantage of this device is the significant force applied to the individual elements of the aircraft: contact with the cable can lead to deformation of the struts of the landing gear of the aircraft, which affects the safety of operation of the aircraft and can lead to aircraft accidents.

Known brake system ATU-2M

((https://ru.wikipedia.org/wiki/Aerofinisher. 10/29/2017) containing racks located symmetrically to the axis of the runway, catching the network connected to the racks using a cable and loops.

The disadvantage of this device is damage to the design of the aircraft due to the significant effort to stop the aircraft and the lack of the ability to quickly disconnect the capture network when exceeding the allowable forces on the structure of the aircraft.

The problem this technical solution is aimed at is the insufficient safety of the aircraft stopping on the runway.

The technical result, the solution of which this technical solution is aimed, is to increase the safety of the aircraft stop on the runway and to prevent the destruction of the elements of the aircraft.

The technical result is achieved by the fact that the device for ensuring safe braking of an unmanned aerial vehicle with a squib cartridge contains racks located symmetrically to the axis of the runway, a catching network connected to the posts using loops, a cable passing through the loops connecting the catching network to the posts, the squib connected to the cable, and a dynamometer mounted on the cable and connected to the igniter with an electric circuit.

The essence of the utility model is illustrated in FIG. one.

FIG. 1 - a device for ensuring safe braking of the aircraft using a squib. Here:

1 - racks;

2 - squib;

3 - dynamometer;

4 - cable;

5 - catching network;

6 - loop;

7. electric circuit.

A device for ensuring safe braking of an unmanned aerial vehicle with a squib cartridge contains racks (1) located symmetrically to the axis of the runway, a catching network (5) connected to the racks (1) using a cable (4) and loops (6), a squib (2) ) connected to the cable (4) and dynamometer (3) connected to the igniter (2) with an electric circuit (7).

The operation of the device is as follows. The aircraft is caught by a catching net (5) fixed to the posts (1) with the help of loops (6) through which the cable (4) passes. The force exerted by the aircraft on the capture network (5) is measured by a dynamometer (3), which is connected by an electric circuit (7) to the squib (2), and when the allowable force is exceeded on the aircraft glider, an electrical impulse is generated, which is supplied from dynamometer (3) through the electric circuit (7) to the squib (2) and the cable is fired (4), disconnecting the catch network (2) from the struts (1), increasing the braking safety of the aircraft and preventing deformation of the aircraft glider.

The claimed device significantly increases the safety of braking of the aircraft and prevents deformation or destruction of the airframe due to the use of an airfield braking system with a force measuring device (dynamometer) and a squib, by opening the catch network from the racks when the allowable force on the airframe is exceeded.

Claims (1)

A device for providing safe braking of an aircraft, comprising racks located symmetrically to the axis of the runway, a catching network connected to the stands by means of loops, characterized in that it further comprises a cable passing through loops connecting the catching network to the stands, a squib connected to a cable, and a dynamometer mounted on a cable and connected to the igniter with an electric circuit.
