EXPERIMENTAL AND THEORETICAL RESEARCH ON THE HYDRODYNAMIC CHARACTERISTICS OF LARGE HUB TO DIAMETER RATIO PROPELLERS

Abstract

Experimental results are presented of the side force generating characteristics of propellers with a large hub to diameter ratio, due to cyclic pitch variations. The effect of the cyclic pitch on the propeller torque and thrust are examined as well. In addition a theory was formulated for calculation of the properties of large hub to diameter ratio propellers. The theory enables one to optimize the design of the propeller with respect to efficiency. The first numerical results of the theoretical analysis are given.
