Arc heater nozzle heating test with hydrogen combustion products
Abstract
A single-edge expansion test nozzle was tested to obtain hypersonic vehicle flight-level nozzle heating data with simulated hydrogen combustion products. The test objectives were to extend the database for nozzle design and computer code validation, and also to analyze flow patterns using oil flow visualizations. A total of 34 runs were made for 15 and 25 degree nozzle ramp angles and water content of zero and 15 mole percent. Higher water produced higher heating rates, as did a higher enthalpy and lower ramp angle. Test data compared favorably with BARTZ and BLIMPK88 computer code predictions.
