Wind Tunnel

Pressure, vacuum and gas flow measurement for wind-tunnel testing of aerodynamics and propulsion

At Chell Instruments, our testing and calibration technology is used in many of the world’s leading wind-tunnels and test environments.

For over 40 years, we’ve supported clients in aerospace, motorsport and automotive with the solutions they need to develop better vehicles.

Our product ranges – particularly our data acquisition (DAQ) pressure sensors and quick-disconnect (AQDC, SQDC and QDCM) couplings – are used extensively in wind tunnels to measure the impact of developments in aerodynamics.

Our measurement technology is also helping with the introduction of electric aircraft – including wind-tunnel development of their airframe and electrified propulsion.

Measurement technology helping designers develop the next generations of vehicles and aircraft in wind tunnels


We have over 40 years’ experience supporting the development of vehicle aerodynamics for performance, stability and cooling.

Working with our partners in Formula 1, we provide equipment and expertise which help them reduce drag, increase downforce and win races.

Within domestic and commercial vehicle design, our products are used within wind tunnels to develop aerodynamics to improve performance, handling and efficiency.

We’ve engineered solutions which maintain very low uncertainties in high-vibration environments, helping gather critical data from wind-tunnel testing. 


Our technology is used at the forefront of modern aerospace development within wind tunnels – both for conventional aircraft and helping develop electrified aviation.

Our equipment is being employed in wind tunnels in Europe, Asia and America to develop electric propulsion for commercial light aircraft.

The world’s two largest manufacturers of jet engines use our technology to help continually develop their ranges for commercial and military applications.
