LIFTING SURFACE CORRECTIONS FOR 4-BLADED OPTIMUM C.P. PROPELLERS

Correction factors for ideal angle of attack due to loading and thickness, and for camber due to loading are presented for 4-bladed 0.3R hub propellers, with NACA-66 thickness distribution. The calculation of the the factors is based on propeller lifting-surface theory. The propellers are optimum free running propellers with chordwise loadings identical to NACA a = 0.8 meanline. The tables presented in the report are direct and unfaired computer output.
