What is DRS in F 1 racing car?

The full name of DRS is drag reduction system, and the Chinese translation is adjustable tail. It is a tail technology that uses the principle of airflow to apply to racing cars, mainly to reduce the air resistance of vehicles and improve the speed.

In 20 1 1 season, a brand-new adjustable tail (DRS) system was introduced in the world formula one championship (F 1 championship) to reduce the tail downforce, reduce tire friction and other resistance, and improve the tail speed.

The tail of formula racing car is generally spoon-shaped from front to back, and the curvature of the lower surface is greater than that of the upper surface, thus creating a pressure difference between the upper and lower surfaces of the tail and obtaining "aerodynamic negative lift", that is, downward pressure.

In addition, the rear half of the tail of Formula racing car is a wing with an angle of 70-80 degrees from the horizontal plane, which makes the air flow upward at high speed along the shape of the tail, which is also the "up-washing effect".

DRS principle:

The design concept of DRS follows the F-Duck launched by McLaren in 20 10 season.

When the car enters the designated area of the track where DRS is allowed (generally long straight, also called DRS area), the driver presses a button to flatten the upper and lower wings of the tail, so that the airflow can smoothly flow through the upper half of the tail of the car, so as to reduce the "up-washing effect" and further reduce the downforce (air resistance) of the tail.

Let the car reduce the air pressure at high speed, that is, it can reduce the friction resistance of the car tires, so as to obtain higher speed, so as to have the opportunity to overtake the car in front. According to the data of the International Automobile Federation (FIA), turning on DRS will increase the vehicle speed by 10-20KM/H (km/h).
