The Department must take the vehicle through the design process and calculate the initial parameters for designing, then a process of iteration must be done until a satisfying design is achieved, also the performance parameter must be calculated within the design process. A wind tunnel testing of different components of the aircraft need to be done in order to compare the results with the calculated parameters. Then, a rigorous simulation of the design must be done on FLUENT to verify the calculated parameters, wind tunnel testing results and prototype testing results. The task of the Aerodynamics Department is one of the most important parts of the Solar Car Design Project and it is one of much responsibility.
