The invention discloses an aircraft undercarriage and an aircraft in the technical field of aircrafts, and particularly relates to a multi-buffering undercarriage for a large vertical take-off and landing unmanned aerial vehicle. The undercarriage comprises a fixing plate and two symmetrically-mounted buffer mechanisms, each buffer mechanism is composed of a connecting frame, a connecting plate, a mounting plate and a plurality of buffer assemblies, and the first buffer assembly comprises a spring and a shock absorber; the second buffer assembly is composed of a mounting block, a rotating rod, a bearing rod and an absorbing plate; the third buffering assembly is composed of a buffering part and a connecting cylinder and is connected with the rotating rod through a connecting rope to achieve dynamic buffering. In addition, rolling wheels and rubber anti-skid pads are arranged at the bottom ends of the bearing rods, and the ground contact performance is enhanced. The design effectively absorbs landing impact force, protects the unmanned aerial vehicle and equipment carried by the unmanned aerial vehicle, and improves take-off and landing safety and stability. Through multiple buffering mechanisms, the undercarriage adapts to different take-off and landing environments, the maintenance cost is reduced, and the undercarriage has wide application prospects.
