The tunnel is capable of speeds of hover to 0.3 Mach, with a dynamic pressure range of 0 to 160 pounds per square foot. It includes a fully automated test-model positioning system and airspeed controller, state-of-the-art data collection ...
Webthe wind tunnel. After the dynamometer is secured to the wind tunnel, the fan will then be turned on and set to a given operation frequency which corresponds to a calibrated velocity (TBD). The fan should be allowed to run for a few seconds to ensure a steady flow of air ensuring a more constant velocity. Speed Control Instructions
High subsonic wind tunnels (0.4 < M < 0.75) and transonic wind tunnels (0.75 < M < 1.2) are designed on the same principles as the subsonic wind tunnels. The highest speed is reached in the test section. The Mach number is approximately 1 with combined subsonic and supersonic flow regions. Testing at transonic speeds presents additional problems, mainly due to the reflection of the shoc… marriage license california processWebThis dissertation introduces the need for adequately correcting for wall interference in subsonic half-model wind-tunnel testing in both pre-stall and post-stall conditions.
