A computer program for calculating the flow fields in axisymmetric or two-dimensional inlets has been written. The program has been written to handle inlets designed with smooth compression surfaces and for which the attached bow shock falls outside the cowl lip. The method of characteristics has been used to calculate a uniform field of points and at each of these points the total pressure, Mach number, local flow angle, and static pressure ratio are printed. The numerical procedures used are fully described and a test case is presented.
Recently, Zoe Ashford of Cranfield University has gone over the program very thoroughly correcting errors and adding program features that have brought the code into compliance with the latest Modern Fortran standards. Thank you, Zoe!
