In the automotive world, wind is one of the obstacles that every car must face. The most aerodynamic cars can beat the wind to run smoothly.The aerodynamic aspect is indeed an important thing for every vehicle. Because the car body that flows with the wind will help support fuel efficiency or reduce exhaust emissions, and make the car able to drive with low power.
As reported by carscoops, it is stated that the aerodynamic system in a vehicle has started sticking since Chrysler introduced the Chrysler Airflow system. At the time of introducing the Tatra T77a, which was estimated to have a value of 0.212 Cd.
Aerodynamics in cars is also known as the Coefficient of Drag (COD), resistance or air resistance when the car is moving. The smaller the COD, the smaller the air resistance. Air resistance in aerodynamics in automotive, can affect vehicle stability, and also the efficiency of fuel oil (BBM) to vehicle performance. In addition to the air resistance factor, there are 4 airflow forces that can be experienced by a moving car. First, the lift or upward lift which is influenced by the influence of speed, fin shape, streamline or aerodynamic design. Second, the down force, which is the downward force on the car. The factors are chassis construction, car design, load placement, additional accessories, tire shape, center of gravity, passenger weight, and spoiler placement.
Furthermore, thirdly, turbulence force, which is the force that occurs at the rear of the car in the form of … Read More
