Propeller-Induced Pressures on a Rudder-Like Surface.

摘要

Total propeller-induced fluctuating pressures were measured on a rudder-like surface, at zero deg rudder angle, located downstream and in the slip-stream of the propeller. The amplitude and phase of the blade-frequency portions of the measured induced pressures were determined for operation in uniform flow. The effects of propeller-rudder clearance, propeller-loading, blade skew, and blade warp on the blade frequency pressure were determined.
