Abstract

PURPOSE:To permit an airplane to make landing with a short aitstrip safely and easily by equipping the plane with a wheel chute, which is accommodated in the wheel upon being coupled with the axis, released at an appropriate timing after landing and opened, and thereby shortening the ground run of the plane with the pneumatic resistance of the chute. CONSTITUTION:When a pilot 12 turns on a wheel chute switch 13 installed in a cockpit, a hydraulic actuator 23 is operated, and a wheel chute 10 and a cable 11 are strucken to outside the wheel 9. As the cable 11 is coupled with a wheel chute coupling part 24 of the axis 19, the wheel chute 10 can be opened with no interference of the cable 11 with tire 20. When the wheel chute 10 is opened in this fashion, an air resistance acts on it to decelerate the plane 1, and its ground run at landing can be shortened. Instead of the hydraulic actuator 23 as mentioned above, a powder cartridge 26 may be used. The wheel chute 10 may also be operated automatically without being operated by the pilot 12.

That is, conventionally, when landing, the wheel brakes 31 are
Although used in both military aircraft, the aerodynamic brake 32 was mainly used in civilian aircraft, the engine reverse thrust 33 was also used mainly in civilian aircraft, and the drag chute 34 was used in military aircraft. Therefore, its use is limited depending on the model, and there is a problem that the landing run distance cannot be sufficiently shortened. In addition, since the wheel brakes 31 are frequently used, they are subject to severe wear, resulting in a large loss in parts replacement costs and manpower costs. In other words, when using the wheel brakes 31, the pilot 12 operates them, so if the pilot makes a second mistake, the wheel tire will go flat, the driver will be stuck on the runway 17, the airport will be closed, and many other aircraft will be adversely affected. or caused damage.
