14x22-Foot Subsonic Tunnel
(1993-L-00502): As in most other large, subsonic wind tunnels, the 14-by 22-Foot Tunnel uses a single large, variable-speed fan to generate its air flow. It is used to study low-speed aerodynamics. Both powered and unpowered models of various fixed and rotary wing aircraft are tested in the in this facility which can be operated as a closed test section with slotted walls or as one or more open configurations when the sidewalls and ceiling are removed to allow extra test capabilities, such as flow visualization and acoustics testing. It was built in 1968 on the site of the 7x10 foot 300 mph tunnel. Wind speed in the test section of the tunnel range up to 230 mph.
