Aerodynamics of V/STOL flight

This book, developed from a set of notes collected over the years in connection with a helicopter aerodynamics course, integrates the field of V/STOL aerodynamics into a discourse on helicopters. A presentation of some general theoretical and applied aerodynamics emphasizing in particular the use of the momentum theorem is first given. This is followed by the development of a finite wing theory. Propeller and helicopter rotor theory is next covered for both the static and forward flight cases. Consideration is given to both momentum and vortex theory in the design and analysis of propellers and rotors. Other subjects discussed include the application of boundary layer control for delaying both separation and transition, and the thrust augmentation of jets by the entrainment of a secondary flow.
