The Effect of Pitch on Force and Moment Characteristics of Full-Scale propellers of Five Solidities

Abstract

Effect of variations in angle of pitch on the aerodynamic characteristics of several propeller combinations was investigated. The results indicate that the propulsive efficiency decreases as the angle of pitch increases. The loss due to pitch increased with increased solidity and was greater at the higher blade-angle settings. A greater solidity increased the vertical force and generally increased the yawing moment. A greater blade angle generally increased the forces and the moments measured.
