A METHOD OF CALCULATING THE SPINDLE TORQUE OF A CONTROLLABLE-PITCH PROPELLER AT DESIGN CONDITIONS

Abstract

A procedure for calculating the spindle torque and for determining the optimum spindle axis location of a controllable-pitch propeller at design conditions is presented. From the blade geometry and theoretical pressure distribution the hydrodynamic and centrifugal forces acting on the blade are obtained, and from the distribution of these forces the spindle torque is calculated. The optimum spindle axis location is then determined by an iteration process. An example is included to illustrate the procedure.
