Abstract

The invention discloses a combined take-off and landing device for a hypersonic vehicle wheel-ski, which comprises a main buffer outer sleeve (1), a main buffer piston rod (2), wheels, a buffer actuating module and a ski assembly; the buffering actuating module is arranged on the main buffer piston rod (2) at the side surface of the wheels; the buffer actuating module comprises an air cavity (8),an oil cavity (9) and a floating piston (16) which are coaxially arranged; the air cavity (8) is vertically fixed below a buffer actuating module bracket (7), the oil cavity (9) is arranged outside the air cavity (8), and a spring (18) is arranged between the air cavity and the oil cavity; the floating piston (16) is arranged in the air cavity (8) ; a hydraulic sensor (12) for detecting the pressure in the oil cavity (9) in real time is arranged at the lower end of the oil cavity (9) and feeds back to an airplane main control system. The device has the advantages of small size and light weight, and can be applied to a hypersonic vehicle with strict limitation requirements on the size and performance of the take-off and landing device.

Description

technical field [0001] The invention relates to the technical field suitable for autonomous take-off and landing of hypersonic aircraft, in particular to a combined take-off and landing device for hypersonic aircraft. Background technique [0002] Hypersonic aircraft refers to an aircraft that can fly at a speed greater than 5 Ma. It has the characteristics of quick response, super penetration, and flexible maneuvering. It is a new concept weapon that combines strategic deterrence and actual combat application capabilities. This kind of aircraft is mainly used to perform tasks such as force projection, specific area detection and surveillance, ground strike and defense, information support, attack weapons and strategic projection platforms, etc., and has extremely high military value. [0003] This type of aircraft has difficult coordination contradictions with the take-off and landing system in some outstanding overall designs. On the one hand, the aerodynamic shape of a h...
