摘要: The level of nitric oxide contamination in the test gas Langley Research Center Arc-Heated Scramjet Test Facility and effect on scramjet engine performance were investigated analytically. A finite rate chemical analysis was performed to determine levels produced facility at conditions corresponding Mach 6 8 flight simulations. Results indicate that range from one three mole percent, corroborating previously obtained measurements. three-stream combustor code with chemistry used investigate effects performance. causes a small increase heat release thrust for investigated. However, constant uncertainty suggests ranges no net effect, an about 10 percent
