Aerodynamic Calculation for Helicopter Lifting Rotors in Steep Descent (Vortex Ring Method) (Aerodinamicheskii Raschet Nesushchevo Vinta Vertoleta na Razhimakh Krutogo Snizheniya Metodom Koltsevykh Vikhrei),

Abstract

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)
