Unmanned aerial vehicle piston

Abstract

The utility model discloses an unmanned aerial vehicle piston which comprises a piston body and further comprises four arc bags which are fixedly arranged at the top end of the piston body, and every two arc bags form a group. Wherein the two groups of arc bags are symmetrically arranged relative to the center of the piston body, the sizes of the arc bags in each group are the same, the top of the piston can correspond to the shape of a valve rod face at the top of an air cylinder, so that the compression ratio of the piston is increased, meanwhile, the metallographic phase of the piston is fine and compact, and the strength and the wear resistance of the piston are improved; the piston can bear higher temperature and load, the rotating speed of an engine reaches up to 10,000 revolutions, operation is stable, noise is low, an unmanned aerial vehicle loaded with the piston can fly at a high altitude at a high speed, foreign technical blockade is broken through, domestic unmanned aerial vehicle piston replacement is achieved, and the industrial development bottleneck is broken through.
