2. Introduction
The team’s objective was to design an aerodynamics package for the ODU formula 1 racecar.
The purpose of the aero package is to provide maximum downforce and minimum drag on the car in order to achieve faster lap times.
The team decided to work on the aero package in 4 different parts: front wing/nose cone, sidepods, undertray/diffuser, and rear wing.
The process for design for each element was broken down into three stages; research, design, and analysis

3. 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.

4. Nose Cone
First Nose Cone Iteration
Iterative process was used to develop the nose cone shape in accordance with frame changes
Designed primarily to cover the front portion of the frame with the impact attenuator attached and reduce drag
Current Nose Cone Model

5. Front Wing Optimized based on research of scholarly articles and books
Completed full design analysis utilizing XFLR and Solidworks with a wide range of Reynolds Numbers
3D printed model complete

6. Nose Cone and Front Wing Results
Nose Cone CFD results:
30 mph
Front Wing CFD results:
30 mph
Front Wing XFLR airfoil results
Eppler 420 had the highest amount of downforce
There was a 42% decrease in drag from the first iteration to the final
Lift also decreased but is considered to be negligible

7. 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

10. Diffuser
The main purpose of the diffuser is to direct airflow in a manner that will increase downforce at the rear end of the car.
Important considerations:
Design should not obstruct the engine, wheels, or frame
Design must be in accordance with FSAE Rules
Three major iterations were made before coming to final design
Iteration 1: After Formula Critique
Iteration 2: After Landman Critique
Iteration 3: Final Design

11. Diffuser Results Simple design produces optimal results
Final design creates low pressure vortices at the exit
Abides by all previous considerations

12. Side pods
Results: The short side pod design had a higher mass flow rate than the traditional diverging/converging design of sidepod, due to the very low expected velocity of this event. A converging exit is still used to lower pressure at the exit of the side pods.

13. Side Pods
Purpose is to provide protective housing for radiator, and increase efficiency of the heat exchanger
Efficiency was optimized for mass flow rate through the side pod
Since the heat exchanger is currently being redesigned, the size of the side pod will need to be altered before being fabricated, so that it fits the new radiator tightly
