The invention belongs to the field of structural design of unmanned helicopters, and mainly relates to a multifunctional skin structural design of an unmanned helicopter. The structure comprises an outer skin (1), an inner skin (2), an inspection opening cover body (3), hinges (4) and an air inlet channel (5). The outer skin (1) and the inner skin (2) extend to the two sides of a middle helicopterbody from the upper portion of the middle helicopter body of the unmanned helicopter. The outer skin (1) and the inner skin (2) are riveted in a sealed mode to form a cavity. The hinge (4) is detachably connected to the position of the inspection opening (13) of the outer skin (1), the inspection opening cover (3) is rotationally connected with the hinge (4), and the air inlet channel (5) is formed in the front portion of the skin structure and fixedly bonded to the outer surface of the inner skin (2). The skin, the oil tank and the air inlet channel are integrally designed, and the advantages of multiple functions, few parts, light weight and the like are achieved.
