Theoretical Analysis of Cycloidal Propellers.

Abstract

An inviscid, two dimensional, theoretical analysis was made of a vertical axis propeller in order to predict its performance in a uniform flow. The propeller characteristics required are the number of blades, the blade chord and camber, the propeller radius, and the blade angle variation with angular position of the blade around the propeller disk. The flow condition required is the advance ratio. A detailed description of blade wakes is developed in order to obtain blade-wake interference as related to blade loading, blade angle of attack, blade circulation, and propeller side force, thrust and torque. Average values of propeller forces and torque are predicted.
