Abstract : The design and operation of supersonic inlets is discussed. The means by which the incoming flow may be decelerated to a subsonic velocity are enumerated and evaluated. This report covers diffusers which employ internal compression, external compression or a combination of the two. Experimentally determined values of the total pressure recovery, the capture-area ratio and the inlet drag are compared with those determined from available theories for all types of diffusers. The discussions which in general refer to axisymmetric configurations usually may be applied with equal validity to two-dimensional diffusers. However, some specific problems of the latter are treated. The effects of boundary layer are considered in some detail as are the problems of oscillating flow. (Author)
