Abstract : An experimental investigation was made of the effect of an applied magnetic field on the bow shock of a blunt body in hypervelocity air flow. Quantitative measurements of the stand-off distance were made in a three-inch electromagnetic shock tube with free-stream velocities up to 22,000 feet per second. The test body was a hemispherical cylinder containing a coaxial pulsed magnet coil in the nose which produced field strengths at the stagnation point of up to 40 kilogauss. The application of the magnetic field displaced the bow shock upstream and the stand-off distance increased by a factor of 7.5 for the condition, nondimensional parameter = 69. The experimental results were compared with theory and good agreement was obtained within the range of experimental conditions. (Author)
