What is the flow-vis paint and aero rake on an F1 car in testing?
Formula 1 teams utilize pre-season testing to gather data on their aerodynamic performance through methods such as flow visualization paint and aerodynamic rakes. This year’s pre-season test will take place on February 21-23 at Bahrain International Circuit, which also hosts the opening grand prix on February 29 – March 2. Flow-vis paint, a fluorescent mix applied to specific car parts, is used to examine the airflow and create lines that provide valuable insights into the car’s aerodynamic performance. Teams must be cautious not to apply too much or too little paint, as it affects data collection. The analysis of flow-vis lines helps identify any issues with airflow separation, which can lead to increased drag and reduced downforce. With limited wind-tunnel testing, flow-vis paint has become even more significant in modern-day F1.
