The
8x6 SWT provides customers with a facility capable of testing large
scale aeropropulsion hardware.
- In a continuous airstream at Mach numbers from 0 to 0.1 and 0.25 to 2.0
- At varying Reynolds Numbers from 3.6 to 4.8x106/ft and altitude conditions (1,000 to 35,000 ft), depending on Mach number
- In either aerodynamic (closed) or propulsion (open) cycle without exhaust scoops
- Employing high accuracy data systems to support steady and transient data acquisition
- Supported by a variety of systems including Schlieren, sheet lasers, GH2 fuel, high-pressure air, and hydraulics
- 1-in. diameter perforations allow for either 3.1 or 6.2 percent porosity variation for test section boundary layer control
