| 摘要： | During April 1996, qualification tests for the subsonic operation of the 10- by 10-Foot Supersonic Wind Tunnel (10 x 10 SWT) were conducted. These tests proved that the facility could be safely operated over the subsonic Mach number range of 0 to 0.36 either by using the air circulation fans of the facility air dryer or by operating the primary drive compressor with one, two, three or all four of the electric drive motors. During the qualification tests, an existing flow field survey rake was used to collect total and static pressure data in the test section. This rake was used for all the surveys made at the operating conditions tested during the qualification tests. The data showed that the spanwise Mach number distribution at the test section centerline was acceptable and that the goal of 0.005 variation in Mach number was met for most of the subsonic operating conditions. |
