Drag Reduction in Automobile. Rear Spoiler

      Аннотация: Automotive vehicle’s performance, safety, maneuverability be influenced by multi-disciplinary factors such as car engine, tires, aerodynamics, and ergonomics of design. With the recent years, inflation in the fuel prices & the demand to have reduced green x0002 house emissions have played a significant role in redefining the car aerodynamics. The shape of the vehicle uses about 3% of fuel to overcome the resistance in urban driving, while it takes 11% of fuel for the highway driving. Besides, automotive vehicles have become so much faster experiencing uplift force which creates unexpected accidents. This brings the idea of using external devices, which could be attached to the present vehicle without changing the body. Even though these vehicles typically have a more rigid chassis and a stiffer suspension to aid in high-speed maneuverability, a spoiler can still be beneficial. This paper is based on the design and developments of the effects of external device which will be spoiler that mounted at the rear side of the vehicle to make the present vehicles more aerodynamically attractive.
