The invention discloses an air vehicle shock absorption foot stand which comprises an inner shaft provided with a semi-closed inner cavity, wherein a spring is arranged in the inner cavity of the inner shaft in a sleeving manner; the inner shaft is arranged in a sleeve in a sleeving manner; the bottom end of the inner shaft is connected with an inclined frame; and the inclined frame is connected with a pulley assembly. According to the air vehicle shock absorption foot stand, an inner sealing structure is formed in a manner that the sleeve and the inner shaft penetrate through oil seal, and the spring mounted inside, by the action of resistance oil, allows extension and contraction of the inner shaft to exert buffering and shock absorption effects; the incline frame fixed with the pulley assembly absorbs partial impact force when the inner shaft extends out, so that an outer force acting on the pulley assembly is weakened greatly; after a magnet ring is powered-on, the magnet ring generates a magnetic field and absorbs round sheet iron fixed on a right wheel hub, so that braking and speed reducing effects are exerted; the air vehicle shock absorption foot stand is compact in structure, high in precision smooth, smooth and stable in operation and high in practicability; the speed reducing and braking sensitivity and the reliability of the pulley assembly are high; and the service life of an air vehicle is prolonged effectively.
