High-accuracy aerodynamic calibration and development
Located at our facility in Dunsfold Park, Surrey, our wind tunnel is dedicated to high-accuracy aerodynamic calibration and development, and serves three primary roles:
- Calibration of Aerosensor multi-hole probes.
- Development and validation of new probe designs
- Calibration of customer probes
Wind tunnel design
The tunnel is an open-return, open-jet design with a 20:1 contraction ratio, producing a 140mm jet of highly uniform, low-turbulence airflow at speeds up to 275mph.
In the working section, a fully automated 3-axis traverse system positions the probe in Z and rotates it about both the yaw and pitch axes simultaneously. Combined with automatic speed control, this allows us to run fully scripted calibration sequences of probe position and wind speed while logging at 100Hz.
This delivers dense, repeatable datasets for both production calibration and advanced development work.
