Abstract

The invention discloses a composite material leaf-spring type landing gear and a manufacturing method thereof. The composite material leaf-spring type landing gear includes a continuous fiber shell body, foam layers, a fuselage connecting bush, a first airplane wheel connecting bush and a second airplane wheel connecting bush, wherein the foam layers are filled in the continuous fiber shell body,and the fuselage connecting bush is arranged in the center position of the continuous fiber shell body. The fuselage connecting bush is connected with a fuselage. The first airplane wheel connecting bush is arranged at one end of the continuous fiber shell body, and the first airplane wheel connecting bush is connected with an airplane wheel. The second airplane wheel connecting bush is arranged at the other end of the continuous fiber shell body, and the second airplane wheel connecting bush is connected with the airplane wheel. The problems of small load bearing and small span of a current composite material leaf-spring type landing gear are solved, the weight on the premise of raising load is reduced, and the composite material leaf-spring type landing gear is used for large and medium-sized aircrafts.

Description

Technical field [0001] The invention belongs to the field of aircraft structure design, and particularly relates to a composite material leaf spring type landing gear and a manufacturing method thereof. Background technique [0002] The landing gear is an important structural component of the aircraft. It is used for the aircraft's take-off, landing, ground taxiing, ground parking, taxiing and braking during taxiing. It absorbs and consumes the relative motion of the aircraft with the ground during the above motions. Impact and turbulence energy, and its performance directly affect the safety of the aircraft. [0003] The existing landing gear has problems: the existing composite leaf spring type landing gear has a small load-bearing ratio (the ratio of load-bearing weight to self-weight), and it is expensive to pay for large load-bearing; at the same time, due to the small load-bearing ratio The existing composite leaf spring type landing gear can not be used for large and medium...
