Abstract : The report treats the nonequilibrium air flow around blunt bodies at high altitudes and reentry conditions. The inverse method is employed, and a reduced form of the Navier-Stokes equations is solved by finite difference techniques. Solutions are obtained for the flow around bodies which generate spherical, parabolic, and hyperbolic shock shapes. Body shapes closely resembling spherically blunted cones are obtained. The present solutions are compared with a very limited data base and other calculations. The results are shown to agree reasonably well with the data and the independent calculations.
