Elementary data concerning the air inlets and afterbodies of subsonic and supersonic aircraft are presented. The author stresses the material significance of some parameters, such as stationary and non-stationary distortion ratios, and the adequation of the air inlet and nozzle to the flight Mach number. The solutions adopted for each type of aircraft are described and commented: subsonic airliners, fighter aircraft with large angles of attack, Mach-2 or Mach-3 supersonic airliners. Brief mention is made of hypersonic nacelle. Special consideration was given to the role and operation of boundary-layer bleeds, the interest of by-passes, the introduction of 'variable-cycle engines,' adaptation of the geometry to the angle of incidence and to yawing, anti-radar discretion and orientable thrust.
