PERFORMANCE CHARACTERISTICS OF THREE PROPELLERS WITH VARYING PITCH DISTRIBUTIONS ON AN INCLINED SHAFT

A series of three commercial propellers with systematic pitch reductions at the hub were characterized at zero and 15 degrees shaft angle, over a range of cavitation numbers and advance coefficients. In addition to the usual thrust and torque forces, horizontal and vertical side forces were measured. These experiments showed that varying the pitch distribution of these propellers changed the type of cavitation on the propeller without significantly affecting the performance of the propeller.
