Theoretical analysis of one-stage windmills for reducing flow distortion

Robert E. English, Peggy L. Yohner
Jun 1957

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.
