Chinese-English Translation:

The shape of a car’s wing is similar to that of a car’s wing when it’s driving at high speed, so it’s very easy to get the lift of a car when it’s driving at high speed. The structure of the spoiler is just opposite to the wing of the aircraft, so it can provide a downward pressure for the vehicle when it follows the vehicle at high speed, so as to restrain the lift of the vehicle.

I believe many car owners have seen that there will be a big tail in the rear of the car. The scientific name of the tail is the spoiler in our title. What is the function of the spoiler?

Students who have studied fluid mechanics should have known about the Bernoulli effect

Bernoulli effect

Bernoulli effect is a theory put forward by “father of fluid mechanics” Daniel Bernoulli in 1726. The simple theory is that “when the fluid velocity is faster, the pressure on the contact interface between the object and the fluid will be smaller, otherwise, the pressure will be larger.”

The reason why we are familiar with the aircraft can fly freely in the sky is based on this principle. Let’s take a look at a section of the wing.

We can see that the wing of an aircraft is a flat bottom and convex top shape, which makes the air velocity above the wing greater than below, that is, the pressure below the wing greater than above, which provides a lift for the aircraft. As the aircraft advances faster and faster on the runway, the lift will become greater and greater, and finally the aircraft will fly to the sky by it.

Now let’s look back at the cars running on the ground. We will find that the shape of the car is very similar to the wing, which is also convex and flat. Therefore, when our car is driving at high speed on the road, the car will also get a lift, which is very easy to affect the driving stability of the vehicle.

The application of the spoiler can restrain the lift very well. Let’s look at the side shape of the spoiler.

I can see that it is a flat top and convex bottom structure. This structure is just opposite to the wing of the aircraft, so it can provide a downward pressure for the vehicle when it follows the vehicle at high speed, so as to restrain the lifting force of the vehicle.

I believe now we should be able to understand the role of car spoiler.
