    The effects of jet control on the aerodynamic characteristics, performance, and stability of a 5-deg semiangle slender cone missile configuration are studied. Tests were made in the Cranfield University College of Aeronautics hypersonic gun tunnel using both sharp and blunted cones. The study was conducted at a Mach number of 8.2 and a Reynolds number of 392,700, based on base diameter, at pitch angles of -15 to 15 deg. The boundary layer was laminar. Air was used as the working gas for both the freestream and the sonic jet. The tests employed schlieren photography to study the overall flowfield. Quantitative studies of the effect of the jet have been made by pressure measurements. The forces were measured with a three-component balance equipped with semiconductor strain gauges.
