The invention belongs to the technical field of aircrafts, and particularly discloses a vertical take-off and landing aircraft landing system, a control method and an aircraft. The landing system of the vertical take-off and landing aircraft comprises a take-off and landing mechanism, an energy absorption mechanism and a braking mechanism. The landing gear comprises a rack, a supporting frame and aircraft wheels arranged at the lower end of the supporting frame, the energy absorption mechanism is arranged on the rack and used for absorbing kinetic energy generated when the supporting frame is turned outwards, the braking mechanism is used for adjusting braking force of the aircraft wheels so as to adjust the turning amplitude of the supporting frame, and when the aircraft lands, the braking mechanism actively adjusts the friction coefficient between the landing gear and the ground so as to adjust the turning amplitude of the supporting frame. The size of friction acting of the undercarriage and the ground and acting of an undercarriage energy absorption system is adjusted, so that the vertical acceleration of the fuselage of the aircraft is reduced, the fuselage load is reduced, the risk that the fuselage and airborne equipment are damaged due to plastic deformation is reduced, the load transmitted to passengers is reduced, the safety and reliability of the whole aircraft are improved, and safe landing of the aircraft is guaranteed. And the risk that the aircraft is damaged due to hard landing is reduced.
本发明属于航空器技术领域,具体公开了一种垂直起降航空器着陆系统、控制方法及航空器。其中垂直起降航空器着陆系统包括:起落机构、吸能机构、制动机构;起落机构包括机架、支撑架和设置于支撑架下端的机轮,吸能机构设置在机架上且用于吸收支撑架外翻时的动能,制动机构用于调节机轮的制动力以调节支撑架的外翻幅度,当航空器着陆时,制动机构主动调节起落架与地面的摩擦系数,以调节起落架与地面摩擦做功、起落架吸能系统做功的大小,从而减小航空器的机身垂向加速度,进而减小机身载荷,降低机身及机载设备发生塑性变形而损坏的风险,减小传递到乘员的载荷,提高整机安全性及可靠性,保证航空器安全着陆,减小航空器因硬着陆致损坏的风险。
