Always wanted to work in Formula One? Then join the Voyager-AirShaper F1 team!
We've created a virtual challenge to optimize the aerodynamics of the Voyager-AirShaper F1 car through AirShaper simulations. The current design started life as a visual styling exercise - featuring a bespoke blue livery - 3D modelled by Voyager. But the car is just that – a styling model. A 3D model created to look stunning and realistic, but not engineered to perform well in terms of aerodynamics.
It doesn't comply with the official regulations, and we don't intend to make it comply. Rather, this exercise is about how you can tweak an existing design to perform better in terms of aerodynamics through modest and realistic changes. And we'll do so based in your input!

This already poses the first challenge - which results will we use?
When it comes to running CFD simulations, you'll always need to make a compromise. Using the Regular Simulation will make it easier on your hardware to process data, the simulations will be faster and easier to run, etc. You'll be able to run more simulations with the same "teraflops" CFD budget, just like real F1 teams. If you're working on large flow structures, this may be enough. But when looking at small scale vortices, or need to mesh small details, it may not be sufficient.
For example, the downforce is higher on the Advanced simulation. In part, this is due to the fact that the Regular mesh was not detailed enough to capture the small gaps between the various wing elements. Actually, even on the Advanced simulation some gap areas are not captured properly!
Design challenge #1 Think carefully about which data to use for which area on the car.
We've added links to download the 3D model & report, to visit the online 3D results and to download the full simulation data. Again, we're facing challenges:
Design challenge #2 Use the online viewer and paraview to gain insights into the flow and share your findings.
The car does not comply with the official regulations and we don't intend to make it to. Nevertheless, the goal of this challenge is to come up with solutions that are realistic and stay close to the rules:
We've set some arbitrary goals:
In reality, things are far more complex, with cars chasing each other, cornering simulations and so on. But for the sake of simplicity, we'll focus on an isolated car going in a straight line at a constant speed of 200 km/h.
To achieve our goals, we will use your input!
Just drop your thoughts on the AirShaper Reddit channel (use the flair "Voyager-AirShaper F1"):
We'll screen the Reddit channel regularly and gather design input. As soon as we have enough input, we will create an updated 3D model, run a simulation and share the results on the Reddit board!
Design challenge #3 : drop designs on the AirShaper Reddit channel
Our deadline is to achieve our goals before the last Grand Prix of the year at Abu Dhabi, November 20th. But that will not keep us from pushing aero updates in the meantime – whenever we've gathered enough input and have made advances, we'll release new results. Step by step, we'll make progress together with you.
We will credit all of the people involved in successful changes, boosting their exposure on social media, to help advance their career.
