Aerodynamic Development and Construction of a Car for Participation in the Eco-Marathon Competition
MetadataVis full innførsel
The authors of this paper were responsible for aerodynamic development of, as well as assisting in the production of components for, the NTNU vehicle for the Shell Eco-marathon competition, DNV Fuel Fighter. A drag reducing end extension, with the intent of delaying flow separation, was designed, produced and mounted on the vehicle. Due to wind tunnel breakdown the final product could not be tested, but the prototype was measured to give a drag reduction of between 8% and 15% for 0 to 15 degrees yaw angle. During the competition the team did not complete an approved run due to technical difficulties with the propulsion and the electronic control system.
