Abstract : A Fortran IV computer program capable of calculating the radiant, viscous, nonequilibrium flow about a blunt-nosed axisymmetric or two-dimensional body is described. The program uses an iterated inverse method in the subsonic transonic region and a modification of the method of characteristics in the supersonic region. The displacement effect of the boundary layer is accounted for by a unique step-by-step method. Equilibrium radiation at the nonequilibrium temperature and composition is computed and used to calculate the radiant heating of the body nose assuming the shock layer is optically thin. An optional calculation of the effect of a magnetic field on the ionized flow in the nose region is included. The report concludes with the analysis of the nonequilibrium flow over a hemisphere cylinder at 14,000 fps. (Author)
