Problems solved by technology

For example, the maximum take-off mass of the Airbus A320 is nearly 100 tons, and the maximum take-off mass of the Boeing 747 is nearly 400 tons. Although the military aircraft is light in weight, the aircraft has a fast landing speed and a horizontal speed of about 200 km / h. It can be seen from the formula that when the aircraft loses control, the kinetic energy is very large, and the conventional method is not enough to reduce the horizontal kinetic energy to zero in a short period of time and eliminate the damage to the aircraft and the people on board.

Embodiment 1

[0022] A safety landing device for an aircraft, which uses a landing vehicle to reduce the speed and kinetic energy of an aircraft 10 to zero in a short period of time, and solves the problem of safe landing of the aircraft 10 due to failure of the landing gear or other equipment failures or weather;

[0023] Described landing vehicle comprises vehicle frame 1, many sets of wheels 2, blocking plate A4, buffer pad A5, rectangular platform 6, multi-row blocking device (shows two rows in the figure), control room 12; Described wheel 2 is installed on vehicle frame 1, the bottom surface of the blocking plate A4 is fixed on the left side of the platform 6, and a plurality of buffer pads A5 stacked and connected together are installed on the blocking plate A4, and the middle and lower parts of the blocking plate A4 have holes that can pass through the nose of the aircraft;

[0024] Described landing vehicle also comprises rotating device, and described rotating device comprises rotat...

Embodiment 2

[0034] A method for safely landing an aircraft, using the above-mentioned aircraft safety landing device, using a landing vehicle to reduce the speed and kinetic energy of an aircraft 10 to zero in a short period of time, so as to solve the problem of safe landing of the aircraft 10 due to landing gear failure or other equipment failures or weather reasons;

[0035] The landing steps are as follows:

[0036] Step 1, the airport control center controls the landing vehicle, and moves at the same speed in the same direction as the airport runway below the aircraft 10; the platform 6 is in a horizontal position, or the angle α between the platform 6 and the horizontal plane is ≤30°;

[0037] Step 2, the airport control center or the pilot controls the aircraft 10 to slow down, and flies with the minimum landing speed and the minimum landing altitude along the sky above the landing vehicle;

[0038] Step 3, aircraft 10 lands on the right end middle position of platform 6 with minimum...

Embodiment 3

[0044] When the aircraft 10 is a smaller fighter in military aircraft, the flying speed is fast and the mass is relatively small. If it lands at this speed, the kinetic energy is proportional to the square of the speed, and the kinetic energy is very large, which will have a large impact on the safe landing device of the aircraft. If the landing speed is reduced, it is equivalent to reducing the kinetic energy and potential energy of the aircraft 10, which is of great significance for safe landing. If other equipment failures occur in the aircraft 10, such as engine failure, tire failure, etc., it is not necessary to put down the landing gear, and the equipment and method of Embodiment 1 and 2 are adopted to realize safe landing.

Abstract

The invention discloses an aircraft safe landing method and a landing device. A landing car is adopted to reduce the speed and the kinetic energy of an aircraft to reach zero within short time to solve such safe landing problems of the aircraft due to undercarriage failures; the landing car includes a frame, multiple sets of wheels, a stop plate A, buffer pads A, a platform, multiple rows of stop devices and a control room; multiple buffer pads A stacked and connected in sequence are mounted on the stop plate A; an airport control center controls the landing speed, angle and direction of the landing car and the aircraft forcedly landed by the failures, gradually lowers the speed of the landing car; meanwhile, an ejector rod is hoisted; a platform rotates around a rotating shaft; an angle alpha of the platform is gradually changed from zero degree to a certain degrees, and meanwhile, the aircraft is decelerated; an aircraft head or an aircraft body or other part and the buffer pads A are deformed; and the buffer pads A coat the surface of the aircraft, so that the resistance is further increased, the speed of the aircraft is reduced to zero, the landing is safe, and the harm to the aircraft and persons therein is eliminated or reduced.

Description

technical field [0001] The invention relates to an aircraft safe landing method and a landing device, which solves the problem of safe landing of the aircraft due to landing gear failure or other equipment failure or weather reasons. Background technique [0002] At present, whether it is a civil aircraft or a military aircraft, there will be an air crash due to failure of landing gear or other equipment failures or weather reasons. When the plane fails to open for forced landing due to a landing failure, the bottom of the fuselage will collide violently or rub against the ground or come into rigid contact with the ground at the moment of landing, resulting in breakage of the fuselage, fire and other accidents, and in severe cases, the consequences of aircraft crash and death. In order to solve the above-mentioned problems, researchers have worked hard and come up with many good methods, such as water landing and paddy field landing, etc. Civilian aircraft carry more passeng...
