Introduction Master Thesis – Aerodynamics CQS

Vettel, Alonso, Rosberg, Hamilton, never heard of them? Well, there is definitely one name which will sound familiar: Michaël Schumacher, one of the greatest Formula-1 pilots ever.

All of them can be considered as true athletes when riding at speeds more then 200 miles/h and undergoing G-forces which are 5 times greater then the normal gravitational acceleration.

One of the greatest aspects of the sport is the cultural aspect. Thousands of people watching how their pilot tries to cross the finish line as the number one champion.

The other part, which takes place in the shades of the cultural aspect of the sport, is the engineering part. After each great F1-pilot stands a huge team, which consist of several highly educated engineers. They have only one purpose, trying to adjust the Formula 1 car to his limits!

CQS GROUP RACING TEAM – KU Leuven can be considered as such a small team, but on another domain, the domain of the Citroën 2 Chevaux. The team is composed of Master students industrial engineering who aspire to develop one of the fastest 2 Chevauxs on the track. Their current race car is the Pegasus 3.1  (

In the year of 2015 the rules of the competition will be drastically changed. By this change the teams aren’t obliged to stick with the geometry of the 2 Chevaux. Due to this change a lot of new possibilities arise for the aerodynamical development of the body. That is where our thesis topic comes in “Design the body of the new CQS racing car”.

Our study will mostly consist of simulating the influence of different shapes on the pressure profile of the car and the drag which is involved. The focus lies on the aerodynamical part, but on the other hand communication with the different research teams from CQS is inevitable. The body can be developed as streamlined as possible, but may be in contradiction with the cooling of the engine. This is just a small example which will lead to a continously process of simulation in meeting the constraints introduced by the different car particles.
In the end we will give some impressions on how the new car could look like with the new rules introduced.
