In order to correlate data obtained in tests on Von Karman radomes with theoretical analyses of thermal stresses in ogive radomes, the temperature and flow conditions around the nose of a blunt radome were investigated, and the results are reported. The blunt nose causes a detached shock wave to form with a transonic flow region developed between the wave front and the nose. Approximate solutions for the velocity components in the highly nonlinear behavior are obtained, and detachment distances compared with published experimental data. Subsonic and supersonic compressible flows are studied, and the incompressible case is shown for comparison. Two numerical examples are given to illustrate the evaluation of initially unknown exponents and the computation of constants in the velocity equations.
