Description

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

There is a known method of braking (ATU-3 installation) (https://ru.wikipedia.org/wiki/Aerofinisher 10/29/2017), which uses the principle of throwing a brake cable stretched across the runway with the calculation of its coverage of the main landing gear, where after the passage of the cable, the nose strut of the landing gear is thrown at a point in time precisely selected taking into account the speed of the aircraft, namely, the first cable clings to the nose strut of the airplane landing gear and lifts the main cable above the runway surface, which captures the rear landing gear and times atyvaetsya a predetermined deceleration amplification.

The disadvantage of this method is the significant effort exerted on individual elements of the aircraft, that is, contact with the cable leads to deformation of the struts of the landing gear of the aircraft, which may further affect the safety of the landing of the aircraft and lead to irreversible consequences.

There is a known method of braking an aircraft (ATU-2M installation) (https://en.wikipedia.org/wiki/Aerofinisher. 10/29/2017), which uses the principle of covering the wing and fuselage of an aircraft with a catching network of nylon ribbons, which minimizes structural damage aircraft, and also makes these installations more versatile compared to aerofinishers (no need to modify the aircraft by installing landing nuts on them.)

 The disadvantage of this method is the complexity of the design, which must be brought to its original state after each use, as well as damage to the design of the aircraft due to the significant effort to stop the aircraft, designed for only one type of aircraft.

The closest analogue to the claimed invention is a method of stopping an aircraft, which consists in covering the wing and fuselage of the aircraft with a catching network, described in the information source SU 247883 A3, publ. 07/04/1969.

The problem this method aims to solve is the unsafe stopping of the aircraft on the runway, which can lead to deformation and destruction of the elements of the aircraft.

The technical result, the solution of which this method is directed, is to ensure a safe stop of the aircraft on the runway and to prevent destruction of the elements of the aircraft.

The technical result is achieved by the fact that according to the method of stopping the aircraft, which consists in covering the wing and fuselage of the aircraft with a catching network, the catching network is additionally disconnected from the struts of the brake system using a squib, while the force from the catching network is measured by a dynamometer, and if it can lead to the destruction or deformation of the airframe, a signal is transmitted from the dynamometer through the electric circuit to the squib, which opens the catching network from the racks, while the set l are made of kapron tapes.

The invention is illustrated in FIG. one.

FIG. 1 - a device for providing safe emergency braking of the aircraft.

Here:

1 - racks;

2 - squib;

3 - dynamometer;

4 - cable;

5 - catching network;

6 - loops;

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 principle of operation of the braking method of an aerodrome installation is that an aircraft that rolls out of the runway is caught by a catching net (5) and, as it moves further under the influence of energy-absorbing braking mechanisms, stands (1) that are connected to the catching net (5), are braked to a complete stop. If the force from the catching network (5) is such that it can lead to destruction or deformation of the airframe, then the catching network is disconnected from the racks using a squib (2).

The claimed method 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 aircraft glider is exceeded.

Claims (1)

The method of stopping the aircraft, which consists in covering the wing and fuselage of the aircraft with a catching network, characterized in that the catching network is additionally disconnected from the struts of the brake system using a squib, the force from the catching network is measured by a dynamometer, and if it can lead to destruction or deformation of the airframe, a signal is transmitted from the dynamometer through an electric circuit to the igniter, which opens the catching network from the racks, while the network is made of kapron tapes.
