- Content
- This research encompasses the design, development and testing of the active Roll Reduction System (RRS) on a Formula SAE car. The system automatically adjusts the angle of attack of the front wing flaps on each side independently while the car is cornering at high speed in order to reduce the roll angle with the aim of increasing its maximum cornering speed. The original “closed” angle of attack of the flaps is at 30.5 degrees, while an “open” position is set at 0 degree. Step motors automatically open the right front wing flap when the car enters a high speed left turn to create additional counter rolling moment, and vice versa for the right-hand turn. Experiments conducted using a Formula SAE car on tracks conforming to Formula SAE rules show that the RRS is able to reduce roll angle by 15%. Average and maximum cornering speeds are observed to increase by 2.64% and 4.76%, respectively.
