Watervliet Subsonic Large Scale Wind tunnel

The Subsonic Large Scale Wind tunnel was purchased from ELD (Engineering Laboratory Design Inc.) in 2006. It is an open circuit tunnel driven by a 100 hp motor and has a contraction area ratio of 9:1 providing a maximum velocity of ~50 m/s. The test section has a cross-section of 80 cm x 80 cm and a full working length of 5 m. It has three optically accessible walls and the ceiling is instrumented with an articulated opaque surface for the generation of pressure gradients down the length of the test section. The Optically accessible side windows are interchangeable allowing for them to be reorganized in many different configurations. Test Models are typically side wall mounted and the lab infrastructure allows for the acquisition of Steroscopic PIV (Particle Image Velocimetry), 6 DoF Load Cell, Static Surface Pressure, and embedded Dynamic Pressure Transducer measurements.

Watervliet Compressible Subsonic Inlet Facility

The compressible subsonic wind tunnel is an open-return tunnel. The facility includes a 100HP blower, a diffuser, a settling chamber, a contraction (having a 5th order polynomial shape), an inlet duct, and a diffuser. The facility is used to test engine inlets. The test section in interchangeable with a minimum cross sectional area of 3.5 in. by 4.5 in. The maximum achievable speed is Mach 0.5 which corresponds to mass flow rates of approximately 2.3 kg/s.
