Abstract
In this paper, the formula for obtaining the absorption horsepower of Moulinet was redrawn, and the physical meaning of the constant in the formula was clarified. Based on this study, it was verified experimentally about the designing method of Moulinet and the calibration method of Moulinet after manufacture. Consequently, the followings were clarified; (1) if the propeller power coefficient was taken to the proportionality constant, the absorption horsepower of Moulinet was proportional to the cube of the revolution, and the fifth power of the Moulinet diameter. (2) if it was Moulinet which carried out the similarity design geometrically with the standard size of Aviation Technical Research Center's type-6 Moulinet, the proportionality constant C1 given in the reference could be used, and the absorption horsepower of the Moulinet was proportional to the cube of the revolution, the cube of the Moulinet diameter, and the side projection area of the Moulinet. (3) the proportionality constant C1 was proportional to the propeller power coefficient CP.
