N-231 High Reynolds Number Channel Facility (4x6 Inch Channel - Atmospheric)
ARC-1980-AC80-0512-4
N-231 High Reynolds Number Channel Facility (Tunnel 2, Airfoil Test Section)
ARC-1980-AC80-0512-1
N-231 High Reynolds Number Channel Facility (An example of a Versatile Wind Tunnel) Tunnel 1 I is a blowdown Facility that utilizes interchangeable test sections and nozzles. The facility provides experimental support for the fluid mechanics research, including experimental verification of aerodynamic computer codes and boundary-layer and airfoil studies that require high Reynolds number simulation. (Tunnel 1)
ARC-1980-AC80-0512-2
N-231 High Reynolds Number Channel II Facility  In this timeframe the test section was designed specifically to test two-dimensional airfoil models. It is equipped with 'through-the-wall' turntables that remotely position the airfoil, with flexible upper and lower walls that can be adjusted to minimize wall interference. Porous side-wall panels provide boundary-layer removal.
