14- by 22-Foot Subsonic Wind Tunnel
The 14’x22′ Subsonic Wind Tunnel assesses conventional performance for low-speed tests of powered and unpowered models of fixed- and rotary-wing civil and military aircraft over a wide range of takeoff, landing, cruise and high angle-of-attack conditions.
Focus Areas and Capabilities

Characteristics
The tunnel can be easily reconfigured for acoustic, tethered free-flight and forced-oscillation (dynamic stability) testing, as well as for motor-sports studies. Investigators can choose from either closed (walls, ceiling, and floor) or open (floor-only) test-section.
Quick Facts
Today, the 14×22 assesses conventional performance for low-speed tests of powered and unpowered models of various fixed- and rotary-wing civil and military aircraft over a wide range of takeoff, landing, cruise, and high-angle-of-attack conditions.
Data Acquisition
The 14×22 is ideally suited for low-speed tests to determine high-lift stability and control, aerodynamic performance, rotorcraft acoustics, turboprop performance, and basic-wake and flow-field surveys.

Fact Sheet
14-by 22-Foot Subsonic Wind Tunnel
Initially names the V/STOL (vertical/short takeoff and landing) Tunnel, then the 4-by 7-Meter Tunnel, and finally, the 14-by 22-Foot Subsonic Tunnel (14×22) was constructed in 1970 to provide an improved understanding of the aerodynamics of V/STOL aircraft.
