Automotive Aerodynamics

Research- Rail Car

Blank

The Blank is the base of the car where the cuts will be made to create the final shape

Cartridge Hole

The cartridge hole allows for the CO2 Cartridge to be held with stability in place

Axel Holes

The Axel Holes will allow the wheels to attach to the car

Side Cut

Both the side cute and the bottom cut shown below are made for shaping purposes allowing for more aerodynamics.

Bottom Cut

Cock Pit

This is created using a Loft

Back Wheel Standoff

The back wheel standoff allow the axles and tires to sit more appropriately while also giving a nicer look to the car, same for front wheel stand off shown below

Front Wheel Standoff

Fillet Edges

All Filet edges allow for a more professional look to the car

Front Rim LX

The rim is made using a revolve around a base. Then the "bolts" are created using domes and extrudes, this is the same for the tires and rear rim

Front Tire

Tires are all made using revolves.

Rear Rim PX

Rims are also made with revolves

My CO2 Car Design

I started with creating my own blank. Where I added filets and axels.

The cartridge's hole was added. This allows the CO2 cartridge to sit properly in the car allowing for best results on race day and also prevent injuries.

The car was then tested through flow simulator to see how aerodynamic it is. The first run is on the left. It was shown that there was a lot of drag in the windows so I added windows and put it back through flow sim as seen on the right.
