The invention provides a ground steering device with an air cushion type take-off and landing system and a control method of the ground steering device. The ground steering device comprises the air cushion type take-off and landing system and a folding undercarriage with a steering mechanism. The folding undercarriage with the steering mechanism comprises an unlocking actuating cylinder, a foldingactuating cylinder, a piston rod, an undercarriage outer cylinder, the steering mechanism, a torque arm and an airplane wheel. A supporting plate is arranged at the bottom of the air cushion type take-off and landing system. The undercarriage outer cylinder is connected with the bottom of the supporting plate of the air cushion type take-off and landing system through the unlocking actuating cylinder and the folding actuating cylinder. The lower side of the undercarriage outer cylinder is connected with the airplane wheel through the steering mechanism and the piston rod in sequence. The steering mechanism is connected with the airplane wheel through the torque arm. The air cushion type take-off and landing system replaces a traditional wheel undercarriage, the total mass of an aircraft is reduced, the requirements for take-off and landing sites are lowered, the take-off and landing environment of a fixed wing aircraft is greatly widened, and the problem that a traditional air cushiontype take-off and landing system is poor in controllability is solved.
Description
technical field [0001] The invention relates to the field of air-cushion landing systems, in particular to a ground steering device of the air-cushion landing system and a control method thereof. Background technique [0002] Amphibious take-off and landing aircraft is a research hotspot in various countries. The air-cushion landing gear is one of the take-off and landing devices for amphibious take-off and landing. It can adapt to various complex take-off and landing terrains and greatly expands the capabilities of fixed-wing aircraft. takeoff and landing environment. [0003] Air-cushion landing gear was developed in the 1970s. It installs the annular elastic air cushion body with holes on the bottom of the aircraft fuselage. When the pressure of the air cushion body increases, the internal air is discharged from the exhaust hole. When the air fills the cavity surrounded by the annular air cushion body and the ground, Air just overflows from cavity, so just forms one dec...
