Introduction to Automobile Tail Wings

operational principle

The working principle of a car tail is similar to that of an airplane wing, but unlike it, the airplane wing generates upward lift, while the car tail generates downward pressure. When driving a car, due to the shape of the tail wing, when air passes through the tail wing, the upper air pressure is greater than the lower pressure, and according to aerodynamic principles, a downward pressure is generated.

Advantages Explanation

When a car is driving at high speed, the air flow rate in the upper part of the car body is fast, resulting in a lower air pressure than the lower part of the car body. According to aerodynamic principles, an upward lift is generated, and the rear wing of the car is precisely to counteract this lift.

It can be seen that its main function is to reduce the lift at the rear of the vehicle. If the body lift is too high, it can easily lead to reduced grip and poor high-speed stability. The addition of tail fins improves driving safety, and at the same time, due to increased grip, power also increases, achieving the goal of fuel saving.

In addition, cars with added rear wings will make people feel more beautiful and atmospheric. This is also a good accessory to attract attention.

Limitations

So there are no drawbacks to the rear wing of a car?

Of course not, everything has two sides. When the driving speed of a car is too low, the rear wing of the car cannot play its role, and instead greatly increases the weight of the body, resulting in an increase in fuel consumption.

So this requires that the design must be "just right" to maintain the increased wind resistance and improved performance in the appropriate position.

In urban driving conditions, the speed of a car usually cannot reach the speed at which the rear wing of the car functions, so it is generally not seen in family cars. However, its function and aesthetics are undeniable, and for most friends, the visual impact brought by the rear wing is more important.
