Abstract

The invention discloses a novel landing gear bumper which comprises an outer barrel (1), an outer nut (2), an inner barrel (3), an exhaust nozzle (4), a pressing piece (5), a wear-resistant ring (6), a sliding block (7), a damping plate (8), a valve (9), a valve nut (10), an isolation piston (11), an oil injection nozzle (12), a supporting piece (13) and an air charging valve (14). Through arrangement adjustment of an oil-gas cavity and brand new design of the structural form, the bumper with the contrary work manner of a conventional bumper is achieved. The bumper is in the shortest state when being not borne with an external load, the bumper extends when being borne with the external load, the structure of a landing gear is enriched, and a technical foundation is provided for meeting special requirements of airplanes.

Description

technical field [0001] The invention belongs to the technical field of aircraft structure design and relates to a novel landing gear buffer. Background technique [0002] Conventional landing gear buffers are in a compressed state when the aircraft lands; after the aircraft takes off the ground, the buffers are in a fully extended state. For the landing gear of some special configurations, it cannot meet its working requirements. [0003] The working mode of the landing gear buffer studied by the present invention is opposite to that of conventional buffers. When the aircraft lands and receives ground loads, the buffer is in an elongated state; when the aircraft takes off, the buffer is in a compressed state. Contents of the invention [0004] Purpose of the present invention: the novel buffer provided by the present invention can meet the needs of special landing gear, and provides technical possibilities for the configuration development of the landing gear. [0005] T...
