    Calspan’s Subsonic, Transonic Wind Tunnel is a continuous flow, variable density, closed-circuit facility with an 8 foot x 8 foot test section. Test conditions are set via independent control of Mach number and one other pressure-dependent variable for constant Reynolds number, static pressure, dynamic pressure, or total pressure operations. in the NASA Langley National Transonic Facility, the NASA Ames ft wind tunnel, and the European Transonic Wind Tunnel. In the NASA Ames ft wind tunnel, data have been obtained at only a chord Reynolds number of 5 million for a wing/body/tail = 0 degree incidence configuration. Data.

After the Second World War NACA engineers began to work on improving wind tunnel performance in the transonic range (Mach to Mach ). It had long been known that airflow within the test section of a transonic wind tunnel did not represent the actual conditions of free flight.

      European Transonic Wind Tunnel Since this investigation was funded by the European Commission as part of the ESWIRP project, the available budget only allowed for testing over a limited range of conditions.

The background to the need for high Reynolds number wind tunnels is outlined together with options. The main advantages of the cryogenic option are. Abstract. Until recently, the problem of low test Reynolds number has limited the usefulness of wind tunnels, especially at transonic speeds.

For general-purpose testing, we achieve the best solution to the problem of low test Reynolds number when we operate a relatively big tunnel (2 × 2 m test section or larger) at a relatively high pressure (up to 3 or 4 bar) at cryogenic temperatures.

With its 8m test section and airspeed up to Mach 1 it is the largest transonic wind tunnel facility in the world. [15] On 22 June Curtiss-Wright financed construction of one of the nation's largest subsonic wind tunnels in Buffalo, N.Y. Propulsion Wind Tunnel 16T.

The facility has two foot by foot long test section, closed-circuit wind tunnels. One is transonic (16T), one is supersonic (16S). 16T can be operated from Mach numbers to 16S is currently inactive, however, when it was operational it could operate from Mach numbers to The calibration of a wind tunnel is a necessary, yet often neglected, process needed to ensure accurate and repeatable test data.

In general, a wind tunnel calibration program encompasses many related topics—basic operating condition calibration, flow quality mapping, wall interference, and model blockage corrections are all topics that can be addressed as part of a tunnel calibration program. Transonic aerodynamics—especially in terms of the transonic wind tunnel—constitutes a critical chapter of aerodynamic science.
