Memorandum presenting an experimental investigation of the aerodynamic loading on one blade and of a two-blade teetering rotor conducted in forward flight for a tip-speed-ratio range of 0.08 to 0.29 at a disk loading of about 2.4 pounds per square foot and a tip speed of about 480 feet per second. Chordwise loading distributions at five spanwise stations and the variation of section loading and total blade lift with azimuth position are presented. Results regarding the performance data, section aerodynamic loading, spanwise loading distribution, total blade lift, and rotor-disk load distribution are provided.
