Abstract

The invention discloses a replaceable foot structure for a legged landing gear. The replaceable foot structure comprises a mechanical connection interface, a force sensor and a replaceable foot end, wherein the upper end of the replaceable foot end is detachably connected to the lower end of the force sensor; the upper end of the force sensor is connected to the mechanical connection interface; and the form of the replaceable foot end comprises, but not limited to, a buffer type foot end, a disk type foot end, an electromagnetic absorption type foot end and a spiny hemisphere type foot end. The replaceable foot structure designed by the invention can be used in cooperation with the legged landing gear, so that an aircraft can satisfy landing and parking requirements under the condition ofdifferent geology, topography and terrain.

Description

technical field [0001] The invention relates to the field of aircraft design, and in particular relates to a replaceable foot structure for a leg type landing gear. Background technique [0002] Vertical take-off and landing aircraft includes helicopters, multi-rotor aircraft and other types. At present, the main forms of vertical take-off and landing aircraft landing gear include wheeled landing gear and skid-type landing gear. Due to the poor adaptability and flexibility of these two types of landing gear, the vertical take-off and landing aircraft has high requirements on the flatness, slope and stability of the landing surface. When encountering special landing environments, such as rocks, In complex terrain environments such as large slope terrain, shaking ship surface, soft grass, etc., it is impossible to take off and land. [0003] Leg-type landing gear is a new concept of landing gear proposed in recent years. This type of landing gear is based on the concept of bi...
