The report describes calculations of the aerodynamic characteristics of a helicopter rotor at any angle of attack in a flow with comparatively high velocity. The study is concerned with the sloping descent of a helicopter and should be regarded as a first attempt to establish a theory of the aerodynamics of steep descent for helicopters. It is based upon the vortex ring method of aerodynamic calculation for lifting systems in steep descent. (Author)
