The team

The refurbished 10x5 Wind Tunnel is a highly reconfigurable temperature-controlled facility with two test sections offering a wide range of features covering just about any study involving airflow. It provides an excellent facility for aerodynamic development and safety evaluation studies of everything from road and race cars to aircraft, buildings and structures. The lower test section is a full 20m long (one of the longest test sections in Europe) and a 3m x 1.5m cross-sectional area. It is equipped with a rolling road, traverse and full boundary layer control. The upper test section is in effect a large wind testing arena 18m in length and a massive 5.7m x 2.8m cross-sectional area. Both test sections are outfitted with an intelligent fully computerised control system and tunnel local area network for the distribution of data. Brand new National Instruments hardware and state-of-the-art LabVIEW based data-processing software enable the user to make maximum use of the facility.

The lower section continues the tradition of the previous tunnel with very high-quality flow and the facility is complemented by a comprehensive range of instrumentation which enable measurements of force, pressure and flow velocity to be made accurately and efficiently.

As well as offering an all-round aerodynamic testing solution, the lower test section is highly optimized for race car testing. Capable of speeds of up to 40m/s, it has an automated support strut and integral 6-component force balance. This greatly simplifies the testing of road vehicles. The rolling road can be yawed to simulate the effects of crosswind and the tunnel uses a novel high-precision wheel drag cell system supplied by Flow Dynamics. A smaller 4.5 x 4 working section tunnel is also available when large scale testing is not required.
