the Facilities

Industrial-scale facilities in academic surroundings provide for nimble and responsive capabilities to study complex fluid phenomena ranging from sub-sonic to hyper-sonic.

Tri-Sonic Wind Tunnel

A 12"-by-12" blow-down wind tunnel facility capable of flows from Mach 0.3 to Mach 5.0. Optical access for non-intrusive diagnostics. Rapid air-system recharge allowing 4-6 runs/hour typical. Capable of supporting combusting flows, laser and aero-optical engagement, free-release separation testing, and powered inlet/nacelle configurations.

Anechoic Jet Laboratory

Gaseous propane or methane fuel jet test rig provides for continuous operation at total temperatures reaching 1000 K at Mach 1.5 for a nominal jet diameter of 2". Fully anechoic configuration for acoustic field measurements. Precision controlled traverse system for detailed investigation of flow phenomena with modern laser-based diagnostics.
