FSAE Rules Front Mounted Devices: In plain view, any part of any aerodynamic device must not be Further forward than 700 mm (27.6 inches) forward of the fronts of the front tires Wider than the outside of the front tires measured at the height of the hubs. When viewed from the front of the vehicle, the part of the front tires that are more than 250mm (9.8 inches) above ground level must be unobstructed. Joseph

FSAE Rules Location Rear Mounted Devices: In plain view, any part of any aerodynamic device must not be: Further rearward than 250 mm (9.8 inches) rearward of the rear of the rear tires Wider than the inside of the rear tires, measured at the height of the hub centerline. In side elevation, no part of the rear wing or aerodynamic device (including end-plates) must be higher than 1.2 meters above the ground when measured without a driver in the vehicle mason

Diffuser Iteration 1: After Formula Critique Recreated design to fit the curves of the frame better and added splitter. Added ramps on the step plane to try and send air over the rear tires. Iteration 2: After Landman Critique Removed splitter and fins to reduce weight. Created the tail end of the diffuser to a spoon-like shape in order to increase the downforce as well as avoid contact with the engine. Gabrielle

Iteration 3: Created flat step-planes to avoid contact with sidepods. Created more gradual angles for tail end of diffuser in order to have an easier design to fabricate.

FSAE Rules All forward facing edges of aerodynamic devices which are not on the front of the car, must have a minimum radius of 5 mm. When loaded with a force of 45 lbs in any location and direction, no aerodynamic element my deflect by more than 25 mm, with no more than 5 mm of permanent deflection. Driver must be separated from all sources of heat by at minimum a 25 mm air gap, no direct contact with heated surface, and a 0.4 mm metal firewall. No line of sight may be permitted between the point 4" from the bottom of the tallest drivers helmet and any portion of the fuel or cooling systems. Aaron

Side Pods Completely redesigned to reduce cost versus the plan from last semester. Gurney flap, ducting, and vents removed, and the shape was vastly simplified. Original insert design Revised design Jake

Results All designs are currently in their final stages and ready for 3D printing. Although more testing and design modification is scheduled, ultimately our team has already created a fully functional aerodynamic package for the SAE Formula vehicle competing in the Spring 2018 semester. The design allows for ODU to be a much more serious competitor at the Michigan competition as well as a foundation for evolutionary designs by future SAE club members. Carmen
