About the Competition
Formula 1 in Schools is an international competition, in which more than 50 countries participate. Germany is one of them. The main goal is to construct a miniature racing car by using CAD software, which is then built with modern manufacturing methods like Multi Jet Fusion. A professional painting is also necessary. The racing time of the car is one of the most important parts – it determines 1/5 of the points. The race itself takes place on a 20-metre racing track. The cars are driven with a CO2 cartridge and gain speed up to 20 metres per second. Nearly half of the maximum points are made up by the production and the race of the cars. So, where can you get the rest of the points? Besides the car the team has several other tasks: One of them is to create two portfolios with eight pages each. The first one is called “Portfolio Technic”. Here, information about the car itself, the construction and the testing are written down. The second portfolio is the “Portfolio Enterprise”, which is about the team’s project management and the marketing concept. In addition, the partners and sponsors are noted. Furthermore, the team has to hold an eight-minute presentation on the competition day, in which they present the team roles, their logo and the design. At last, each team needs to build their own pit display to represent their sponsors on the competition day.
German Championship 2022
Hamburg Championship 2022
Hamburg Championship 2022
Our Hamburg championship vehicle had the name “Pistris” which is Latin for shark. It got its name due to the “Gilles” on the rear spoiler and due to the “Finn” at the vehicle’s front. As you can see, we were more focused on controlling the airflow than just minimising the aerodynamic resistance. We also tried two completely new things. First, we abolished the backbox behind the rear wheel. We did this to have more control over the mass and the centre of mass of our vehicle. Second, we implemented an impeller to our wheels and an air channel that forces the air to rotate our wheels faster. We called it the “Rotation Support Device” (RSD).
Whenever we had an idea we wrote it down in a shared document, so we never forget any of our ideas. Then, we used Solid Edge, a Computer Aided Design-software (CAD), to design a 3D-Model of our idea. Afterwards, we used Computational Fluid Dynamics-software to analyse the airflow of our vehicle. We compared different ideas and choose the best of them.
We had many unusual ideas, which were never done before in an F1 in school car. Thus, we had to figure out how to implement these ideas into a final vehicle. Our production manager Christoph did a lot of research, due which we could figure out the best way to produce our car as precisely as possible and to give it a clean surface. Our entire chassis was 3D-printed in SLS. We used polyamide 12, which is one of the most solid materials available for SLS printing. And this was a good choice. At first, we thought that our “Gilles” might break, but they did not. In the end, we were able to build the faster car at the Hamburg championship.
German Championship 2022
After having the fastest car at the Hamburg Championship we thought that we might have a car that we just have to change a little bit for the German championship. How little did we know? After comparing our time to these of other regional competitions in Germany it was very clear that we had still a lot to do. We did again research and find quickly our biggest mistakes. Firstly, the RSD. The idea was meant to fail. We made some major thinking mistakes. Our vehicle from the German championship had no RSD. The reason behind the idea of abolishing the backboxes was primarily for the reason of reducing the vehicle’s mass. But, our car from the Hamburg championship was actually even too light at first, thus we brought them back. Lastly, we changed our front spoiler. Our new spoiler did not need the “Finn” anymore and the new spoiler provided more control of the airflow. Due to our new front spoiler, our car also got a new name: “Sphyrnidae”. The Latin word for hammerhead shark.
Sometimes theory is not everything. We had to prove that our ideas would really make our car faster. Not only had we visual proof due to our virtual wind tunnels, but also due to physical prototype tests. We had over 500 test drives with more than five different prototypes. Especially, out front spoiler was the focus of our tests. But also physical phenomena like mass and centre of mass. With all this knowledge combined, we were able to get the second faster car at the national finals. Our car was 0.080 seconds faster than it was at the Hamburg championship before. In this competition, this is a lot.

Did we arouse your interest?
We hope that we have proven ourselves. It is not normal to give that much information about a car on a homepage. But we did it anyway due to two reasons. First, the regulations at the world finals are completely different. Thus, many things are not allowed anymore at all. Second, we want to prove to potential sponsors that we know what we are doing. That we are really interested in improving our vehicle and we really want to spark your interest in our team. If we were able to do so, we are happy if you contact us as soon as possible! Thanks.
