CAD - College

During my time at college we had to design a lego gravity powered car in line with the Project Design Specification (PDS). This was then to be raced against fellow students. When designing the car we had very little support.

This meant I had to do a lot of research into how to design the parts while still being inline with the PDS for example, weight distribution, wheel diameter and ride height. There were also changes to roles during the year to fix potential error in the regulations for example how the wheels could affect the ride height. The inspiration I used for my design was the Plymouth Superbird due how low to ground it is which is great for aerodynamics in a gravity powered car.

So after doing my investigation it was now time to design the car. The method I used was trial and error. This involved making designs and then changing them based on my CFD testing as shown through the different designs. The final design was after I had all ready done two iterations of CFD testing and more independent reasearch. This lead to me deciding to make changes to the rear of the car to improve airflow of the wing to create more lift.

This taught me that no matter what the challenge with reasearch and testing I can achieve my goal of making a lego gravity powered car in line with the Project Design Specification (PDS).
