It’s official! The 2023 F1 in Schools World Finals have been announced, and the location has been confirmed to be Singapore! We can’t wait for the competition, and we’ve already done lots of preparation. In this blog we’ll provide you with an insight into our progress so far on Innovation’s 2023 World Finals car.

Kasey, our design engineer, has familiarised himself with the World Finals technical regulations and has made progress on multiple new car designs. These prototypes feature some innovative ideas that the team have brainstormed. This includes a new rear wing, as the WF regulations mean that we cannot use the design we had on our Nationals 2022 car. We have done virtual wind tunnel testing on these new designs using Ansys Discovery Live, our CFD software of choice, provided to us by our sponsor Leap. Since we started up working again, we’ve already tested over 30 unique car files. Although we cannot share these new designs publicly yet, we can share that our latest car concept has achieved an average drag force of 0.115N in simulations. Overall, we’ve made a good start in our design process, but we’ve got much bigger goals ahead for our car’s development. We can’t wait to share the innovative design decisions we’ve made on the car with you all in the future.

With some new designs ready, we have also begun manufacturing some testing cars. For the international final, there are many regulation changes which we are learning and adapting to. One of these changes involves using polyurethane foam as the material for the car body rather than the balsa wood we used for Australian National competitions. We recently ordered some foam blocks and Alessio, our manufacturing engineer, has tested milling with them to learn how they differ from the balsa blocks. From our test cuts, we have found that the foam blocks can create a much more consistent recreation of our car, and the cuts have a much better finish than the balsa. This is especially useful for the new complex shapes we’re experimenting with right now on our car designs.

Another advantage of this new milling material is that the foam has a uniform density, meaning each block has a constant mass of 114 grams. This is a great improvement over the mass variety of the balsa blocks as it means we know every block we purchase is quality and useful.

That’s all we have to share with you now. Thanks for supporting Innovation by reading this blog post. Check out our socials through our Linktree to stay updated as we keep growing forwards!
