The Effect of Thickness Ratio on Section Thrust Distribution as Determined from a Study of Wake Surveys of the NACA 4-(0)(03)-045 and 4-(0)(08)-045 Two-blade Propellers up to Forward Mach Numbers of 0.925

Daniel E Harrison, Joseph R Milillo

Abstract

Report presenting testing of two two-blade propellers in the 8-foot high-speed tunnel for a range of blade angles and Mach numbers. The results show that changes in thrust loading due to compressibility effects were much smaller for the thin-blade propeller than for the thick-blade propeller.
