| 内容記述 | This report presents results of gas analyses of Mach 7 Tunnel Calibration Test 139 conducted in the Langley 8-Ft. HTT from May through June of 1998. These tests in support of hypersonic airbreathing propulsion provided a current calibration at the primary test condition for the National Aero-Space Plane Concept Demonstration Engine and a new calibration for the two test conditions that will be used for engine testing in support of the Hyper-X program. Samples taken from three probes on the Flow Survey Apparatus were analyzed using mass spectrometers. Although this wind tunnel doesn't produce a true simulation of flight conditions, test results show that a uniform oxygen concentration of 21 percent was achieved. |
