Abstract

The rear spoiler is one of the main components that affect the aerodynamic performance of the F1 racing car. At present, numerical simulation technology is becoming a research hotspot to study the aerodynamic performance of the F1 racing car. In this paper, we discuss the F1 racing car rear spoiler airfoil selection and three-dimensional design and use three-dimensional simulation software to calculate the impact of different attack angles, velocity, and airfoils on the rear spoiler’s drag force and negative lift. The results show that the RAE2822 airfoil has a good lift-drag ratio at low velocity. When the attack angle is 30°, the maximum lift-drag ratio can be obtained. When the velocity exceeds 60 m/s, the impact on the lift-drag ratio is almost negligible.
