Computer programs have been written to aid the design and analysis of 2-D, axisymmetric, and 3-D supersonic inlets. This report presents the fundamental analytic techniques, the use and operation of the computer programs, and the application to the design of supersonic inlets. The programs are written in FORTRAN IV for use on the 7094 high speed digital computer. The 2-D and axisymmetric programs presented herein are written for generalized inviscid supersonic internal flow problems with uniform or non-uniform inlet entry conditions for entropy, total enthalpy, pressure, Mach number and flow direction. The program capabilities include the intersections and reflections of both family waves, the formation of shocks or expansions at corners, the formation of shocks by coalescence of waves from smooth walls, and the formation of contact discontinuities. The 3-D programs presented herein are written for the calculation of the inviscid supersonic flow fields associated with basic elements of 3-D supersonic inlets. The methods utilized exact and linearized supersonic flow theory with engineering approximations to yield solutions to the following unit problems delta wing flow, conical shock interacting with a plane surface, plane shock interacting with a conical surface, and the interaction of two different conical flow fields.
