Abstract

The aim of this project was to investigate the aerodynamic and structural effects of modifying a Carbon Fibre Toyota Supra TRD 3000 GT Wing to perform dynamic angle of attack updates. These angular updates have been based on an ideal aerodynamic phenomena required under different operating conditions. High speed cornering would see the wing produce maximum downforce, while heavy braking can be enhanced by using the wing blade to create maximum drag.

The realizable k – ε turbulence model was used in a two dimensional representation of the problem within ANSYS FLUENT. This analysis determined that for all speeds, maximum downforce was achieved at a -15° angle of attack. Maximum drag occurred on the wing when it was deployed at -60°, while minimum drag was achieved at 0°.

The magnitudes of the forces obtained from the FLUENT analysis were then compared to data released for the standard Toyota Supra wing. This comparison showed that the downforce was increased by 46.97% over the standard wing.

A near field strain analysis was performed in order to ensure that the carbon fibre wing was capable of withstanding the added forces. An existing wing was loaded with weights in a fibre composite laboratory, while strain gauges measured the amount of strain present in the surface fibres.

Computer based finite element analysis was then used to conform to these strain values. Once the computer model demonstrated the same properties as the real specimen, it was loaded with the maximum FLUENT forces which determined that the wing blade had the ability to operate under the new conditions.
