Aerodynamics of airframe-engine integration of supersonic aircraft

Some major aerodynamic problems involved in the design of the propulsion-system installations of advanced supersonic aircraft are reviewed from the airframe viewpoint.Consideration is given to environmental factors such as flow fields, the airframe boundary layer, airframe-inle t and inlet-inlet shock interference, and jet-airframe interference .New aerodynamic tools available to the designer are discussed and are used along with experimental data to analyze the drag minimization problem.Finally, detailed attention is given to the problem of optimizing the propulsion system itself from the standpoint of inlet and nozzle selection, flow distortion effects, handling of the various secondary airflows, and afterbody drag.
