Nacelle Installation Effects on Propeller Blade Surface Pressure Distributions

A system capable of measuring the time averaged surface pressure distributions on rotating model propeller blades has been developed. A wide range of test conditions have been investigated and results displaying the effects of changes in blade setting angle, advance ratio and number of blades on the blade surface pressures are presented. In addition, the system has been used to experimentally investigate the influence of nacelle type afterbodies on the propeller blade pressure distribution.
