Aero rakes are a critical component of the aerodynamic testing process used by Formula One (F1) teams to optimize the performance of their cars. These devices are used to gather data on the air flow around the car, which is essential for developing the most efficient aerodynamic setup. In this article, we will explore the technical details of aero rakes and their use in F1.
What is an Aero Rake?
An aero rake, also known as a pitot rake or flow-vis rake, is a collection of thin rods that are attached to the back of a Formula One car. These rods are equipped with sensors that measure the air pressure and velocity at various points around the car.

When the car is driven at high speeds, the rods bend and deflect due to the force of the air flowing around them. This deflection is used to calculate the airflow velocity and direction at each point where a rod is located.
How do Aero Rakes work?
Aero rakes work by creating a grid of sensors around the car that measures the airflow around it. As the car is driven, the sensors measure the air pressure and velocity at each point on the rake. This data is then used to create a map of the airflow around the car, which is used to optimize the aerodynamic setup of the car.
Aero rakes are typically mounted to the back of the car, although they can also be attached to other parts of the car, such as the front wing or sidepods. The rake is positioned at an angle to the airflow to ensure that the maximum amount of data is collected.
The sensors on the rake are connected to a data acquisition system that records the data collected during testing. The data is then analyzed by engineers to determine how the air is flowing around the car and how changes to the aerodynamic setup of the car will affect its performance.
Why are Aero Rakes used in F1?
Aero rakes are essential for F1 teams as they provide critical data on the airflow around the car. This data is used to optimize the aerodynamic setup of the car to ensure maximum downforce and minimum drag. Without this data, it would be impossible for teams to determine how to make the car as fast and efficient as possible.
Aero rakes are particularly useful during pre-season testing, where teams are trying to determine the best aerodynamic setup for their car. During testing, teams will often run the car with different aerodynamic configurations to determine which setup provides the best performance. The data collected by the aero rake is used to determine which setup is the most effective.
Aero rakes are also used during race weekends to gather data on how changes to the car’s setup affect its performance. This data is critical for teams as they try to optimize the car’s setup for each track they race on.
Conclusion
Aero rakes are a critical component of the aerodynamic testing process used by Formula One teams. These devices provide essential data on the airflow around the car, which is used to optimize the car’s aerodynamic setup for maximum performance. Without aero rakes, it would be impossible for teams to determine how to make the car as fast and efficient as possible. As F1 teams continue to push the limits of what is possible in terms of aerodynamic performance, aero rakes will remain a crucial tool for achieving success on the track.
