Abstract
The amendment of Formula One racing rules in 2022 has changed the situation of competitions and championships. In the 2022 season, the FIA will allow teams to use the ground effect again after 1978 to increase the possibility of overtaking and make the race more intense. The amendment is the most noticeable change in these years, and it is very effective. Wind tunnel research and the use of ground effect in the field of racing have special significance and practical value. It has always played an important role in the design and performance improvement of the car. In the design of traditional car styling, the influence of ground effect is not taken into account, so that in the course of the race, accidents often occur when the car body is off the ground. The reason is that the adhesion is reduced. The ground effect is an important method to improve the adhesion and stability of the car. In recent years, with the advancement of wind tunnel experiments, wind tunnels are gradually used in the design of racing cars. This paper will analyze the use of Venturi Wind Tunnel and ground effects in F1 and aircraft, and explain how and why adding ground effects to F1 has such a huge impact.
