The NTF is a high-pressure, cryogenic, closed-circuit wind tunnel that uses supercold nitrogen gas at high pressure to duplicate true flight aerodynamics. The NTF can accommodate models as small as one-fiftieth the size of an actual aircraft. Unlike conventional wind tunnels, this facility can adjust airflow to match model size.

Mach Number: 0 – 175 mph

Reynolds Number: 0.1 to 1.2

Pressure: 4 x 106 to 145 x 106 per foot

Temperature: -250 to 150°F

Test Gas: Nitrogen and ambient atmosphere

Test Section Size: 8.2 x 8.2 feet

Area: 66.8 feet

Drive Power: 135,000 horsepower
