摘要
PROBLEM TO BE SOLVED: To provide a rotary wing to be applied to a model rotary wing aircraft, with reality closer to an actual aircraft, and also to provide a method of manufacturing the rotary wing.;SOLUTION: A cylindrical aluminum alloy pipe 10 of a desired length is molded to have a wing cross sectional shape in cross section by rolling. By the molding, the rotary wing 5a for the model rotary wing aircraft is constituted to have a hollow structure. As a result, the rotary wing 5a is considerably reduced in weight. By this rotary wing 5a, a problem of weight due to a metal material is avoided, while producing massive feeling and profound feeling peculiar to the aluminum alloy (peculiar to metal). The rotary wing 5a is made to have a one-layer structure (integrated structure) by molding the aluminum alloy pipe 10 and has a sufficient strength.;COPYRIGHT: (C)2010,JPO&INPIT
