What is special?

Pre-curved rear spoiler

Sport is definitely the best gear for road and track. As aerodynamics has always been a quintessential part of extracting top-notch performance, this carbon fiber spoiler’s visibility is way beyond its striking aesthetics upgrade. You’ll be impressed by the drastic improvement in aerodynamic efficiency and expansion of the car’s overall performance.

Aerodynamic drag force acts on the vehicle’s body resisting its forward motion. The LIFT and DRAG forces are important forces to be considered while designing the external body of the vehicle since it covers about 65% of the total force acting on the complete body.

The rear spoiler is an obstruction to localized airflow that improves the overall airflow around a vehicle. The design of the rear spoiler is a small angle of attack. At α = 0°, the relatively higher surface pressure near the rear end of the spoiler has caused a significant reduction in the Coefficient of lift as compared to the case without the spoiler. In addition, the Coefficient of drag has been slightly reduced. Note that this positive combination – reduction in both LIFT and DRAG – is highly appreciable.

The rear spoiler is an obstruction to localized airflow that improves the overall airflow around a vehicle using the angle of attack of less than 5° in most commercial vehicles.

By introducing the pre-Curvature, the linear straight wing results are partly recovered.

For Stiff, there is a 35% increase in the flutter speed at nominal conditions.

• The damping and Frequency plot with Corresponding plots for the straight wing. It is again seen that pre-curvature leads to a decrease in the detrimental nonlinear effects of lift.

For Flex, the flutter results are similar to those obtained for a lower wing loading, i.e., the lower flutter mode is weaker and the higher flutter mode occurs at lower velocity. Thus even though there is no significant change in the flutter speed, the flutter is weaker in a pre-curved wing and thus might be overcome easily by inherent structural and aerodynamic damping.

• The decrease in flutter speed due to large deflections may be essentially cancelled out by pre-curving the wing to get an approximately straight wing at nominal drive conditions.
