Complex terrain adaptive landing gear of vertical take-off and landing aircraft and landing method of complex terrain adaptive landing gear

Abstract

The embodiment of the invention discloses a complex terrain adaptive landing gear of a vertical take-off and landing aircraft and a landing method of the complex terrain adaptive landing gear. The device comprises at least two landing legs, two movable joints, a scanning detector, a terrain recognition camera and load sensors, wherein upper connecting rods in the landing legs are connected with anundercarriage adapter frame through the movable joints, the upper connecting rods are connected with lower connecting rods through the movable joints, buffer mechanisms are installed in the lower connecting rods, foot end devices are installed at the tail ends of the landing legs, and load sensors are located between the lower connecting rods and the foot end devices; the two movable joints are used for controlling the moving postures of the upper connecting rods and the lower connecting rods respectively; the upper end of the load sensor is connected with the buffer mechanism, and the lowerend is connected with the foot end device; the scanning detector and the terrain recognition camera are mounted below the vertical take-off and landing aircraft; and the load sensors are used for measuring the ground load of the landing legs after the landing legs touch the ground, and controlling the posture of the landing legs by feeding back the ground load of the landing legs to a flight control system. The device disclosed by the embodiment of the invention solves the problem that an existing landing gear is generally poor in adaptability in the landing process.

Description

technical field

[0001] The present application relates to but is not limited to the technical field of vertical take-off and landing aircraft landing gear, especially a complex terrain adaptive landing gear for vertical take-off and landing aircraft and its landing method. Background technique

[0002] Due to the characteristics of vertical take-off and landing, fixed-point hovering in the air, low-speed flight, low-altitude and ultra-low-altitude flight, in-situ steering, and flight in any direction, the vertical take-off and landing aircraft is limited in take-off and landing sites, and the flying space is small, requiring low-altitude and low-speed tasks. As an ideal aircraft, it has broad application prospects. As an important part of the vertical take-off and landing aircraft, the landing gear plays a supporting role when the helicopter is parked and gliding on the ground, and also plays a role in absorbing the energy generated by the vertical descent speed when landing...
