Production manner of rotary wing, and its rotary wing of model rotary wing aircraft

摘要

Topic It is applicable in the model rotary wing aircraft, production manner of the rotary wing, and its rotary wing which possess close real Characteristic with the apparatus is offered. SolutionsBeing cylindrical, in order for profile to become airfoil blade section forma aluminum alloy tube 10 of length of desire, depending upon roll formation, it forms. Because of this, it is possible to form the rotary wing 5a for the model rotary wing aircraft in hollow structure. Because of this, rotary wing 5a becomes something where weight is decreased substantially. According to that kind of rotary wing 5a, while aluminum alloy specific (metal specific) engendering heavy appearance and the profound impression, you can evade also the problem of the weight which hangs on in the metal material. Furthermore, rotary wing 5a aluminum alloy tube 10 structure (integral construction) with becomes more by the fact that it forms, also strength becomes sufficient ones. Choice figure Drawing 3
