Detailed Description

In order to make the objects, technical solutions and advantages of the present application become more apparent, the technical solutions in the embodiments of the present application will be described in more detail below with reference to the accompanying drawings in the embodiments of the present application.

As shown in fig. 1, the landing stabilization system for an escape capsule provided by the present application can be used for stabilizing an aircraft escape capsule 10 on a slope ground after landing, and the landing stabilization system comprises: the parachute shooting gun 21, the parachute 22, the gas generator 23, the buffer airbag 24, the AND gate controller 25, the trigger 26, the plurality of shooting hook guns 27 and the ground penetrating hook locks 28.

The escape handle 11 is arranged in the escape capsule 10, and the escape handle 11 is used for generating an escape signal under the control of an escape capsule passenger so that the escape capsule is separated from the aircraft.

The parachute shooting gun 21 and the parachute 22 are arranged on the top of the rescue capsule 10, the parachute shooting gun 21 is controlled by a program controller, when the predetermined height is reached, the controller sends out a command to enable the parachute shooting gun 21 to shoot out the parachute 22 for enabling the rescue capsule 10 to safely fall to the ground, and meanwhile, the parachute shooting gun 21 generates a primary actuating signal to be transmitted to the door controller 25.

The gas generator 23 and the buffer airbag 24 are installed at the bottom of the rescue capsule 10, and when the rescue capsule 10 reaches the ground, the gas generator 23 is triggered to inflate the buffer airbag 24, and simultaneously the gas generator 23 generates a secondary actuating signal to be transmitted to the and gate controller 25.

The and gate controller 25 is installed inside the escape capsule 10, and receives a primary actuating signal generated by the parachute-shooting gun 21 and a secondary actuating signal generated by the gas generator 23, and outputs a firing signal to the firing device 26 by logically judging the primary actuating signal and the secondary actuating signal. In the preferred embodiment of the present application, the and gate controller 25 outputs the firing signal only when the primary and secondary actuation signals are present at the same time, so as to avoid the malfunction of the single actuation signal and the erroneous output of the firing signal.

A trigger 26 is mounted inside the rescue capsule 10 for controlling the shoot gun 27 to shoot out the ground penetrating hook lock 28 according to a trigger signal.

The shooting hook gun 27 and the ground penetrating hook lock 28 are respectively arranged on each lateral edge of the rescue capsule 10, and stable ground grabbing can be realized by arranging the ground penetrating hook lock 28 on each lateral edge of the rescue capsule 10. For example, in the embodiment of the present application, the rescue capsule 10 has a rectangular structure, and the four lateral edges thereof may be provided with a hook gun 27 and a ground penetrating hook lock 28.

In the preferred embodiment of the present application, the floor stabilization system further comprises an actuating handle 29 mounted inside the rescue capsule 10, the actuating handle 29 being connected to the trigger 26, and the trigger 26 being enabled to generate a trigger signal by pulling the actuating handle 29, so as to control the shoot gun 27 to shoot out the through-the-ground hook lock 28.

Therefore, the floor stabilization system provided by the application has two working modes, namely an automatic mode and a manual mode.

In the automatic mode, after the passenger starts the escape handle 11, the escape capsule 10 is separated from the aircraft, and the controller for controlling the parachute-shooting gun 21 is triggered, when the predetermined height is reached, the program controller sends out an operation instruction to enable the parachute-shooting gun 21 to shoot the parachute 22, and meanwhile the parachute-shooting gun 21 transmits a first-stage actuating signal to the AND gate controller 25; when the rescue capsule 10 falls to the ground, the pneumatic generator 23 is triggered to generate a large amount of gas by impact work and is inflated to the buffer air bag 24, the buffer air bag 24 protects the rescue capsule 10, meanwhile, the pneumatic generator 23 transmits a secondary actuating signal to the AND gate controller 25, the AND gate controller 25 outputs a firing signal to the firing device 26 after performing logic judgment, the firing device 26 outputs the firing signal to the shooting hook gun 27, the shooting hook gun 27 is actuated to shoot out the ground penetrating hook lock 28, and the ground penetrating hook lock 28 is used for grabbing the ground after opening a hook claw underground, so that the rescue capsule 10 is stabilized.

In the manual mode, after the rescue capsule 10 falls to the ground, the door controller 25 fails and does not enable the trigger 26 to generate a trigger signal, at this time, the passenger pulls the actuating handle 29 to output the trigger signal to the trigger 26, the trigger 26 outputs the trigger signal to the shooting hook gun 27, the shooting hook gun 27 is actuated to shoot out the ground penetrating hook lock 28, and after the ground penetrating hook lock 28 opens the hook claw underground, the ground is gripped to stabilize the rescue capsule 10.

The foregoing is merely illustrative of the present application, and the present application is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the scope of the present application should be included in the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
