The Langley airfoil design, technically known as RC4, has managed to “lift off” and find much success in other applications.Ĭarson Helicopters Inc. The improved blade offered significantly greater lift capabilities, less drag, and less pitch (alternating lift and descent of the nose and tail of an aircraft during flight) than its predecessor and other conventional blades, when compared during high-speed flight-performance testing. While these airfoils did not get applied to the Boeing-Sikorsky Comanche rotor, they did advance the state of the art for rotorcraft airfoils. ![]() The helicopter’s airfoils were designed as part of the Army’s basic research program and were tested in the 6- by 28-inch Transonic Tunnel and the Low-Turbulence Pressure Tunnel at Langley. Army engineers working with NASA’s Langley Research Center were part of the Army’s risk reduction program for the LHX (Light Helicopter Experimental), the forerunner of the Comanche helicopter. Advanced rotorcraft airfoils developed by U.S.
