Problems solved by technology

With such a structure, when the aircraft that fails in flight achieves a soft landing, it can avoid violent collision with the ground when the aircraft lands, or cause casualties due to friction with the ground and cause fire and explosion, but the cost of laying the runway is relatively high, which is not convenient Promote application

Abstract

The invention discloses an undercarriage faulty airplane safe landing gear. The undercarriage faulty airplane safe landing gear comprises a landing plate provided with a traction mechanism and a sliding mechanism arranged below the landing plate. An elastic steel sheet with the M-shaped cross section is arranged on the upper portion of the landing plate. A flexible energy relief layer is arranged on the elastic steel sheet. A compensation air bag is arranged in a cavity between the landing plate and the elastic steel sheet. An airplane position automatic correction device is arranged in a concave position in the middle of the elastic steel sheet. The undercarriage faulty airplane safe landing gear has the advantages of being high in anti-seismic buffering capacity, capable of accurately and conveniently conducting positioning, flexible and adjustable in airplane landing position, low in cost, and capable of being popularized and applied conveniently.

Description

technical field [0001] The invention belongs to the technical field of air transport facilities, and in particular relates to a safe landing device for an aircraft with landing gear failure. Background technique [0002] Since the invention of airplanes, airplanes have increasingly become an indispensable means of transportation for modern civilization, which has profoundly changed and influenced people's lives. Since the invention of airplanes, the time for human beings to travel around the world has been greatly shortened. The intricate air routes have connected countries all over the world, providing people with convenient and rapid passenger transportation. Airplanes closely connect people of different races and colors in different regions. Through continuous communication, people sow friendship, convey information, achieve mutual communication, mutual understanding and mutual promotion, and jointly promote human civilization. But, when aircraft provides convenience for...
