Isentropic flow and simple radial equilibrium were assumed in analyzing two windmills for reducing flow distortion. The following conclusions and results were obtained: Wind- mills are inherently limited to flows per unit area lower than those attainable in modern compressor design; at high flows, the uncambered rotor blades must be so thin that blade vibration will be a critical problem.
