Wind tunnel tests in Langley low turbulence pressure tunnel to obtain data of importance for rotary wing aircraft in view of fact that recent trends toward higher forward speeds have resulted in increases in area of very high angle-of-attack region, and forces contributed by this region constitute greater part of total rotor forces than in past.
