Analysis of some interference effects in a transonic wind tunnel

Journal of Aircraft, 1995
The effects of the walls of a test section on a model in transonic flow were investigated by using the AGARD Calibration Model B. Tests were carried out in a closed-circuit pressurized tunnel, with a confined square test section of 1.5 m width, with tapered slots giving a 5% porosity. Two models with different dimensions were used, with 0.85 and 0.056%

Transonic Wind Tunnels

2020
As the air flow around an aircraft is not uniform, locally supersonic zones may exist even under subsonic upstream flow condition, this defines the transonic regime, a condition where both subsonic and supersonic regions coexist.

Optimum transonic wind tunnel

14th Aerodynamic Testing Conference, 1986
The optimum facility to complement existing high Reynolds number transonic wind tunnels is discussed. It is proposed that the facility be cryogenic, have a total pressure of five atmospheres or less, and have a test section on the order of 4- to 5-meters square.
