China3D printingNet August 28th, Formula One (F1) is the world champion of the world car race and its governing body, the International Automobile Federation (FIA), which uses additive manufacturing to help determine the design and rules of the 2021 season.
Every F1 season, the FIA will issue new regulations for cars participating in the championship. The new rules are tested using the implemented prototype car model. Last month, the 2021 vehicle was extensively tested in a wind tunnel using an accurate 50% scale model with the help of additive manufacturing.
The wind tunnel test was conducted by an independent consulting team from the Swiss racing engineering company Sauber, which used its own wind tunnel facilities. Using additive manufacturing to create scale models has brought many benefits to the development team. F1 Chief Technology Officer Pat Symonds said: “50% is a good compromise, because we can still see good details on the model, which may be a certain distance from the real car. So some teams will increase the model. To 60%.

After F1 testing, additive manufacturing proved to be valuable
For the 2021 season, Nikolas Tombazis, head of single-seater technical affairs at the FIA, said that the league has expressed its desire to “break the rules”. This is to push the current regulations to the extreme and find loopholes. An important goal of the 2021 rules is to encourage contestants to exceed each other. Therefore, the FIA has completed unprecedented computational fluid dynamics (CFD) research and development to help its 2021 model car. Conduct wind tunnel tests to help confirm the data generated by the CFD study.
Preliminary testing was completed in January 2019, and 60% of the models in 2018 were tested in the wind tunnel. In the following March, another test was conducted on a 2021 model with 13-inch wheels, but the 2021 season rules are likely to require all F1 cars to use 18-inch wheels on the track. Then in the Sauber wind tunnel in July, 50% of the 2021 models and correctly installed 18-inch wheels were tested.
F1 provided a video describing the wind tunnel test of the 2021 50% scale model, which was run on 18-inch tires for the first time, and this process is usually kept secret by the organization. The automatic rake system of the Sauber wind tunnel can be seen moving behind the car to measure its airflow or “wake”. The wake is monitored, so F1 and FIA can try to improve the ability of cars to follow each other and then overtake the other car.An important factor in measuring the wake of a 2021 vehicle is to pass3D printingGenerate a detailed 50% scale model.
Due to the huge cost of manufacturing models, 100% of the scale cars have been banned for F1 wind tunnel testing. The F1 fleet uses a maximum of 60% of the wind tunnel test models, but F1 and FIA use the advantages of additive manufacturing to produce detailed models at a ratio of 50% without sacrificing accuracy. The smaller size means that there is more space in the wind tunnel behind the car, allowing a more detailed inspection of the car’s wake.
In F13D printing
Many F1 teams now combine additive manufacturing with prototyping and produce parts that can improve car performance.Recently, Jabil, a global manufacturing services company in the United States, announced a partnership with Renault F1 Team to produce F1 cars for the 2019 Formula One World Championship.3D printingcar parts.
