Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings.
As shown in fig. 1-3, the airport runway emergency arresting system using airbag cushion provided by the present invention comprises a pressure sensor 1, an airbag slot 2, a control system 3, a gas generating device 4 and a high strength airbag 5; wherein, a plurality of pressure sensors 1 are densely distributed in the outer areas of two sides of the runway 6; the air bag grooves 2 are sequentially arranged in soil areas outside the shoulders on two sides of the runway 6, a high-strength air bag 5 and at least one gas generating device 4 in a multi-layer folded state are arranged in each air bag groove 2, and an exhaust port of each gas generating device 4 is connected with an air inlet of each air bag groove 2; the control system 3 is arranged in one airbag tank 2 and is electrically connected to all pressure sensors 1 and gas generating devices 4.
The air bag groove 2 comprises an air bag groove cover 21 and an interlayer plate 22; wherein the air bag groove cover 21 covers the upper port of the air bag groove 2; the multiple interlayer plates 22 are arranged on the groove wall 23 of the air bag groove 2 at intervals in a hanging wall mode, and the air bag groove cover 21 and the interlayer plates 22 are both made of easily-folded materials; the uppermost interlayer plate 22 is used for placing the first layer of air bags 51, and the lower interlayer plate 22 is used for placing the rest of the plurality of layers of air bags 52 which are in a curve shape.
The first layer of air bags 51 are high-strength arresting nets on the upper half parts and inflatable air bags on the lower half parts.
The pressure sensor 1 is arranged in the area from 25m outside the center line of the runway 6 to the edge of the runway 6.
The working principle of the airport runway emergency arresting system adopting the airbag cushion provided by the invention is explained as follows:
when the aircraft is about to deviate from the runway 6 for some reason, the nose landing gear of the aircraft must press some of the pressure sensors 1, and then the pressure sensors 1 immediately transmit detection signals to the control system 3; within 80ms after the control system 3 receives the signals, the position of the airplane deviating from the runway 6, namely the position of the high-strength airbag 5 to be unfolded can be judged by analyzing the signals of the pressure sensor 1, and then an inflation instruction is transmitted to the corresponding gas generating device 4; the gas generating devices 4 inflate the inflatable airbag at the lower half part of the first layer airbag 51 in the high-strength airbag 5 connected with the gas generating devices within 60ms, the inflated first layer airbag 51 can be erected to eject the airbag groove cover 21 made of the easily-folded material out of the upper end opening of the airbag groove 2, and the aircraft nose is intercepted by the high-strength barrier net at the upper half part of the first layer airbag 51 and then is wrapped by the inflatable airbag at the lower half part of the first layer airbag 51 and moves forwards together; when the first layer airbag 51 is separated from the airbag groove 2, the second layer airbag is inflated by the gas generating device 4 within 60ms, the corresponding interlayer plate 22 made of the easily-folded material can be broken when the second layer airbag is inflated, then the second layer airbag moves forwards together with the first layer airbag 51, the airplane is supported, and the like is carried out until the rest of the multi-layer airbags 52 are all ejected. The kinetic energy of the aircraft is consumed by the friction between the airbags and the ground until the aircraft stops, thus minimizing the injury to the aircraft and personnel.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes may be made to the present invention by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
