Abstract

The invention discloses a main landing gear of an airplane. The main landing gear is a tube-spring type landing gear, and comprises tube-spring type main supporting poles, bushings, wheel axles, airplane wheels, tires, and a fairing installed on the tube-spring type main supporting poles, wherein one ends of the tube-spring type main supporting poles are connected with the tires by means of the wheel axles and the airplane wheels, and the other ends of the tube-spring type main supporting poles are connected with a fuselage; the bushings are installed on the tube-spring type main supporting poles and are close to the fuselage; the tube-spring type main supporting poles can be inserted into mounting holes formed in a mounting support seat under a floor of the fuselage, and are fixed in themounting holes by means of bolts; the tube-spring type main supporting poles and the bushings installed on the tube-spring type main supporting poles are jointly used for reducing and absorbing the strike energy produced by the contact between the airplane and the ground in processes of taking off, landing and taxiing, so that the shaking and jiggling of the airplane are effectively relieved.

Description

Technical field: [0001] The invention belongs to the technical field of general aviation landing gear, in particular to a main landing gear suitable for trainer aircraft. Background technique: [0002] The Kitty Hawk-700 aircraft is suitable for general aviation fields such as aviation clubs, skydiving, and aerial photography. It mainly uses a front three-point fixed landing gear, which consists of a front landing gear and two main landing gears. At present, the main landing gear used by most trainers on the market, during the process of take-off, landing or taxiing of the aircraft, due to the large impact generated by the contact between the aircraft and the ground, the aircraft is seriously bumped and shaken. For this reason, the present invention provides a kind of main landing gear of aircraft, and this main landing gear can reduce and absorb the impact energy that aircraft produces during take-off, landing and run. Invention content: [0003] The purpose of the prese...
