Optimum Power Plant Configuration for a Supersonic V/S.T.O.L Strike Aircraft: A Review of the Characteristics Required of Engines for Future ‘Vectored Thrust’ Low‐Level Strike Aircraft and a Comparative Evaluation of the Design Features and Performance of the Lift/Thrust and Composite Engine Solutions

Examples of jet‐lift aircraft powered by the diverse systems of the single lift/thrust turbofan and the multi‐engined specialized lifting and propulsion engines are now flying. With the experience gained from these pioneering aircraft, it is appropriate to review the thermodynamic characteristics required of engines for future ‘vectored thrust’ low‐level strike aircraft, having supersonic capability. The relative merits of extreme forms of power plant are discussed from the engine and power plant designer's viewpoint and these are linked with a spectrum of aircraft which lie between these extremes of design.
