Abstract : The purpose of this document is to present a comprehensive, in-depth review of the serious efforts made in the development of VTOL and V/STOL concepts and aircraft other than the helicopter. The time period covered is from the beginning of organized government-sponsored activity in the late 1940's through the present, during which a very large study and development activity has taken place. Conventional helicopters are not included because their development history is a sizeable subject in itself and one which is already well-documented. Included are V/STOL aircraft which do use rotors but are aimed at providing cruise speeds and aerodynamic efficiencies similar to those of conventional airplanes. Although not aircraft in the conventional sense, wingless VTOL vehicles which use direct thrust (rocket or turbojet/turbofan) for lift in all flight modes also are included since such machines do have a close relationship to some of the more commonly accepted forms of VTOL aircraft. This volume contains an introductory review of V/STOL aircraft concepts and the rationale behind them. The concepts are categorized by propulsion system. This volume contains definitive information and technical reviews of the rocket belt, turbojet/turbofan platform type (wingless) vehicles, and turbojet/turbofan vertical attitude takeoff and landing aircraft.
