THE ULTIMATE AERO EXPERIMENT
OUR TWO WIND TUNNELS ARE BASED ON CLASS-LEADING TECHNOLOGY AND OFFER UNIQUE INTERACTION WITH TGR-E’S OTHER SERVICES FOR SPEED, ACCURACY AND MAXIMUM EFFECT.
Both our two wind tunnels use a continuous steel belt rolling road with a maximum speed of 70m/s and are capable of up to 60% model testing, whilst WT1 is also equipped for full-size cars. Thanks to our specially-designed motorbike platform we can also enhance the aerodynamics of road and race bikes.
ACCURACY IS EVERYTHING
Accuracy is the focus of TGR-E’s wind tunnel services and our highly-advanced models include up to 512 pressure measurement channels, accurate to 7Pa and laser technology to ensure correct positioning to 0.05mm accuracy. Even tyre deformation and exhaust gases can be simulated.
Both tunnels also utlise particle image velocimetry (PIV) analysis to visualise flow structures in X, Y and Z planes within the tunnel, allowing direct measurement of local flow velocity vectors, as well as validating CFD predictions of velocity and vorticity fields.
Our ‘wheels on’ approach offers representative suspension kinematics, active suspension pre-load with integrated pushrods and automatic steering.
Successful aerodynamic development depends on accuracy and efficiency, so High Speed Data Acquisition (HSDA) and Continuous Motion Systems (CMS) are available in both tunnels.
In CMS mode, a user-defined programme of ride height, yaw, roll, steer and individual pre-load changes provides continuous motion on a predefined trajectory while the HSDA system is continuously acquiring data at high frequency.
This allows realistic road or track analysis, reducing tunnel time by as much as 70% and increasing the amount of useful data from each individual test compared to standard motion and acquisition systems.
A secure exclusive data analysis tool enables fast and reliable interpretation of results for efficient development. TGR-E’s system synergies allow wind tunnel data to be streamed to the CFD and driving simulator departments.
