rear spoiler (Slingshot Autosculpt) refers to a plate attached above the rear of the installation.
Since the vehicle body is an irregular generally streamlined body, separate air vehicle, the air flows from around the vehicle, and after the passage through the roof, that part of the air will begin to flow down, and here airflow flow rate will be based on the shape of the rear of the decision, such as the rear for a more beautiful, so many rear styling are relatively steep, so the air flow speed will be faster, but also will form as machine the effect is the same wing lift upward, then spoiler effect is reduced without increasing the driving force of the vehicle is increased by the weight of the vehicle under the premise.
If the rear lift larger than the front of the lift, the car will easily lead to excessive steering, rear grip is reduced, the difference between high-speed stability. Therefore, use of the inclination of the rear spoiler, the wind generated directly downward pressure, such as the rear spoiler is generally inclined F1 racing up to 1000 kg of pressure at high speeds 15deg ;,. However, the rear spoiler also increases the air resistance, such as the drag coefficient Fl is close to 1.0 (typically 0.3 to 0.5 sedan). Therefore rear spoiler must be designed quot; spoiler most reasonable degree of increased drag between the improved performance reaches right quot ;, so.
