Engineering Active Spoilers with Enhanced Degrees of Freedom for Optimal Sport Cars Aerodynamics

Abstract The aerodynamics of sports cars is a critical factor influencing their performance, particularly in terms of speed, stability, and efficiency. This thesis investigates the development of an advanced active spoiler system with enhanced degrees of freedom for motion in Pitch or horizontal direction, aimed at achieving optimal aerodynamic control. Traditional active spoiler systems primarily employ (Lift)vertical motion and (Pitch angle) tilt for adjustments to angle of attack to modulate aerodynamic forces. This research introduces an innovative mechanism that enables horizontal motion (Pitch motion, moving in the direction of pitch) of the wings, thus adding an extra degree of freedom to the system. The proposed design encompasses the development of a sophisticated mechanism and actuator capable of precise horizontal movements. This additional degree of freedom allows for an unparalleled level of control over aerodynamic forces, such as lift and drag. Compared to traditional active spoiler systems, this new design covers Three time more area. This increased coverage provides precise control over drag, lift, braking, and cornering forces, significantly enhancing the vehicle's aerodynamic performance. Through comprehensive analysis and calculations, this study demonstrates the effectiveness of the new mechanism in optimizing the aerodynamic performance of sports cars. By integrating horizontal movement, the enhanced active spoiler system can dynamically adjust to varying driving conditions, ensuring maximum speed and efficiency. The findings of this research present significant implications for the automotive industry, offering a practical solution for advancing the aerodynamic capabilities of high-performance sports cars. This study emphasises the beneficial capabilities of multi-degree-of-freedom active spoiler systems as a vital tool in the aerodynamic enhancement of a sports car and lays the ground for the next phase of advancement of automotive engineering. The results affirm that enhanced control over aerodynamic forces can lead to superior performance, marking a substantial advancement in the field of automotive aerodynamics.
