Tests made to determine range of advance ratio and blade angle in which tunnel wall corrections as developed for wings might be used for rotors; lift and drag coefficient data were corrected by standard wing-type wall corrections using full span of rotor as vortex span and area of rotor disk as wing area; data compared to determine at which blade angles and advance ratios corrections gave satisfactory agreement.
