Abstract : Wind tunnel tests of a rotor/wing model were conducted for three purposes: To compare the results of testing the same model in a small and a large wind tunnel; to investigate rotor/wing planform effects on performance and flying qualities; to investigate in detail the low rotor speed range of conversion. The data gathered from testing the 7-foot diameter model in the 8-by-10-foot tunnel and in the 30-by-60-foot tunnel were in good agreement for rotor advance ratios greater than 0.15. (Author)
