Configuration method for creating and manufacturing propellers of e.g. helicopter, involves placing ring on circle, where ring is not maintained in portion that is provided between points of blades, and ring closing periphery of area

摘要

The method involves defining areas of bodies of scalable constituent elements whose projection of paths allows producing blades for centrifugal wheels (D) that include initial points (A). The initial points are individually common to the blades that comprise different reference points (B, C) located on a circle (E) close to largest diameter of one wheel. A ring is placed on the circle and not maintained in a portion that is provided between the reference points of the blades, and closes the periphery of the area between the blades, where height of the portion is same as that of the blades.
