Book Description
The level of nitric oxide contamination in the test gas of the Langley Research Center Arc-Heated Scramjet Test Facility and the effect of the contamination on scramjet test engine performance were investigated analytically. A finite rate chemical analysis was performed to determine the levels of nitric oxide produced in the facility at conditions corresponding to Mach 6 to 8 flight simulations. Results indicate that nitric oxide levels range from one to three mole percent, corroborating previously obtained measurements. A three-stream combustor code with finite rate chemistry was used to investigate the effects of nitric oxide on scramjet performance. Results indicate that nitric oxide in the test gas causes a small increase in heat release and thrust performance for the test conditions investigated. However, a rate constant uncertainty analysis suggests that the effect of nitric oxide ranges from no net effect, to an increase of about 10 percent in thrust performance.Cabell, Karen F. and Rock, Kenneth E.Langley Research CenterNITRIC OXIDE; CHEMICAL ANALYSIS; CONTAMINATION; TEST FACILITIES; SUPERSONIC COMBUSTION RAMJET ENGINES; PERFORMANCE TESTS; COMBUSTION CHEMISTRY; COMPUTATIONAL CHEMISTRY; FLIGHT SIMULATION; MATHEMATICAL MODELS; COMPUTERIZED SIMULATION
