Project from 3D constructor - https://dubina.biz

The car has aerodynamic stability during roll, pitching and yaw. Roll stability is ensured by the location of the center of pressure close to the longitudinal axis of the car. The value of the longitudinal moment, leading to a change in wheel loading with increasing speed, is determined by the distribution of lifting forces acting on the car. The spoiler is used to create the upper contour of the stabilizer, reducing aerodynamic drag, causes negative lifting force on the rear wheels, and this helps to increase the longitudinal stability of the car. A spoiler is an aerodynamic device designed to control the air flow around the car in order to increase the adhesion of the wheels to the road. The spoiler is installed on the rear trunk door. It creates the necessary pressure on the shock absorbers of the rear suspension. It has minimal air resistance and does not create unnecessary turbulence. Due to the pressure from the spoiler on the rear of the car, the adhesion of the rear wheels to the road increases. Wheel adhesion increases braking efficiency. The downforce from the spoiler reduces lift and stabilizes the car. The rear of the car does not lose grip and the car does not skid. It begins to create effective downforce at a speed of 100 km / h. It is rational to use it on a car with an average speed exceeding 150 km / h. At low speed, there is a negative effect from air resistance and the weight of the spoiler. The spoiler is also called a wing because of its main function to create a force directed downwards, not upwards. The angle of attack of the spoiler has a significant impact on its effectiveness. The magnitude of the downforce depends on the angle of attack of the wing. The greater the angle of attack, the greater the downforce, but the angle of attack has a limit. The height of the spoiler installation is important to achieve the optimal balance between stability and grip. The spoiler is made of carbon fiber. It is attached to the rear trunk lid using mounting screws. The screws are screwed into the bases of the spoiler legs from the inside of the door. The area of ​​​​the working surface of the spoiler S = 0.6 m2. Angle of attack α = 40 °. Downforce F = 1111 Newton or F = 111 kg at speed υ = 200 km/h.
