About this ebook
An analysis is presented whereby the free-space oscillating pressures associated with a rotating propeller may be determined at any point in space. This analysis is based on the fundamental Gutin equations without some of the simplifying assumptions. Static tests for several different propellers were conducted in the tip Mach number rang 0.45 to 1.00. Charts are given for estimating free-space pressures for a given propeller. The response of the fuselage to these oscillating pressures is also treated and some factors to be considered in solving the problems of fuselage vibration and noise are indicated.
