Automotive aerodynamics is the study of the aerodynamics of road vehicles. Its main goals are reducing drag and wind noise, minimizing noise emission, and preventing undesired lift forces and other causes of aerodynamic instability at high speeds. Air is also considered a fluid in this case. For some classes of racing vehicles, it may also be important to produce downforce to improve traction and thus cornering abilities.

Designs of are own car
Designs of are own car
In my first design was planning into making it a cow with wheels on the bottom but quickly realized that it would be really hard to make a cow in solid works.
For my second design of are own cars I decided to go for a shopping cart inspired by the shopping cart ricer.
This is the end design of the shopping cart with some design changes from the sketches
Flow Simulation Testing
Flow Simulation Testing
This is the end result of the flow simulation with the modifications to make it more aerodynamic .
The carts on the right and middle are the shopping cart from before the changes one having arrows and the other not.

This is the end result of the car after the supports needed for it and wheels with it.
Race #1
Race #1
In this race I was the car in the first lane where I get my fastest time and win this race
Race #2
Race #2
In this race my car was in lane 2 and got my lowest time and lost this race
Race #3
Race #3
This was the last race I did where my car was in lane 1 and won the race
Calculating the mph for each race
Calculating the mph for each race
Race #1 Time and calculation
Time 1.297 The point .5 being added to the times is the Engine burn time
.5+1.297=1.797
.5 X 1.797=0.8985
60 feet / 0.8985 = 66.7779633 MPH or 66.778 MPH maximum velocity before it started to slow down
Race #2 Time and calculation
Race #2 Time and calculation
Time 1.479 The point .5 being added to the times is the Engine burn time
.5+1.479= 1.979
.5 X 1.979 = 0.9895
60 feet / 0.9895 = 60.937 MPH or 60.937 MPH maximum velocity before it started to slow down
Race #3 Time and calculation
Race #3 Time and calculation
Time 1.321 The point .5 being added to the times is the Engine burn time
.5 + 1.321 = 1.821
.5 X 1.821 = 0.9105
60 feet / 0.9105 = 65.898 MPH or 65.898 MPH maximum velocity before it started to slow down
