TheBrazilian hypersonic scramjet aerospace vehicle 14-X B is a technological demonstrator of a hypersonic airbreathing propulsion\nsystem based on the supersonic combustion (scramjet) to be tested in flight into the Earthââ?¬â?¢s atmosphere at an altitude of 30 km\nand Mach number 7. The 14-X B has been designed at the Prof. Henry T. Nagamatsu Laboratory of Aerothermodynamics and\nHypersonics, Institute for Advanced Studies (IEAv), Brazil.The IEAv T3 Hypersonic Shock Tunnel is a ground-test facility able to\nproduce high Mach number and high enthalpy flows in the test section close to those encountered during the flight of the 14-X B\ninto the Earthââ?¬â?¢s atmosphere at hypersonic flight speeds.A1mlong stainless steel 14-X Bmodel was experimentally investigated at T3\nHypersonic Shock Tunnel, for freestreamMach numbers ranging from7 to 8. Static pressuremeasurements along the lower surface\nof the 14-X B, as well as high-speed Schlieren photographs taken from the 5.5âË?Ë? leading edge and the 14.5âË?Ë? deflection compression\nramp, provided experimental data. Experimental data was compared to the analytical theoretical solutions and the computational\nfluid dynamics (CFD) simulations, showing good qualitative agreement and in consequence demonstrating the importance of these\nmethods in the project of the 14-X B hypersonic scramjet aerospace vehicle.
