F1 Technique: Explaining the Formula 1 wind tunnels

The general shape of a Formula 1 car is defined by the technical regulations of the FIA. Within the rules, engineers design a car that’s not only sleek but more importantly one which must produce massive negative lift called downforce.

Long before their birth, scale models of the actual F1 cars are tested and evaluated in the team’s’ wind tunnels.

A wind tunnel is a tool used in aerodynamic research to study the effects of air moving past solid objects. It consists of a closed tubular passage with the car to be tested mounted in the middle. A powerful fan system moves air past the car; the fan must have straightening vanes to smooth the airflow.

There are in fact two main types of wind tunnels. One type is called an “open circuit tunnel”s with an air entry open to the atmosphere. Formula 1 teams rely on the other type:, the closed circuit wind tunnels. These generate a more uniform flow, in principle, than open circuit tunnels.

They are said to be low-speed closed circuit tunnels. This means that the speed varies between 10 and 100 m/s approximately, and the same air is recirculated. The stream is turned, typically by four 90
