The Channel 5 test facility is an atmospheric inlet blow-down wind tunnel capable of delivering velocities in the test section up to Mach 1.2 external flow. The test section is 22 x 22 inches (0.312m square) and has ventilated upper and lower walls. Motive force is provided by high speed air ejectors downstream of the test section that accelerates air from atmosphere into the test section.
Can be used to evaluate exhaust system performance with air, and acoustics with the use of helium in the core passage of a nozzle simulation. Typical exhaust system models are mounted on the 5 inch diameter air supply sting. A three component force balance measures thrust, normal force, and pitching moment. An ASME flow meter determines the mass flow delivered to the model and the momentum needed for the force balance equation.
Wind on high speed (up to M 1.2) probe testing. Probes mount on top and bottom solid walls on independent turntable plates (capable of mounting multiple probes).
