| Popis: | A single-edge expansion test nozzle was tested in the Large Core Arc Tunnel of the McDonnell Douglas Corporation Aeromechanics Laboratory to obtain hypersonic vehicle flight-level nozzle heating data by using water to simulate hydrogen combustion products. The test objectives were to expand the data base for nozzle thermal design and computer code validation. A total of 34 runs were made for 15- and 25-deg nozzle ramp angles and water content of zero and 15 mol%. Six gauges each of heat flux and pressure were installed along the centerline of the nozzle ramp surface and one each at an off-centerline location. The fixed lower cowl was instrumented with two pressure gauges. Higher water injection rates produced higher heating rates, as did a higher enthalpy and lower ramp angle. Test data compared favorably with BARTZ and BLIMPK88 code predictions with equilibrium chemistry. |
