Aerodynamics, The Invisible Power


Aerodynamics, The Invisible Power

For many drivers, impacting their feelings about a car is just the style body lines and color of the paint. Today we will talk Automotive Aerodynamics, which is closely related with hairstyle and body lines of a car.

Although many cars aerodynamics taken into account when designing the style, there is still a long way to reach better performance, only restricting cost savings.

However, only the aerodynamics, the invisible hand, which becomes one of the keys to winning a racing game. Let’s see air kits car modification everyday, and technology flattening chassis that are only used in sports cars before range. How could improve the performance of a car?

In order to understand the exact effectiveness of air kits and get the best of the Air Force, wind tunnel tests are the steps in need.

Planarization works by reducing air resistance chassis accelerating airflow underneath it, producing a negative to low pressure, resulting in a downward pressure so that the car is more stable at high speeds . This is contrary to the aerodynamics applied to aircraft wings as the plane takes off by negative pressure up. Meanwhile, a flat chassis helps reduce wind noise when driving, making a smooth ride.

At present, the manner declared “planarization chassis technology” of many cars on the market it is just a trick.

The front of a car is even more important in the design of aerodynamics, because it meets the wind at the earliest. So reducing wind resistance Front could help improve engine performance and fuel consumption. In addition to the intake system, engine air cooling system and surrounding braking, special designs are applied to any remaining places that could cause wind resistance, so that before the car is only found with the wind in a proportion .

Effect of airflow is also used in hood that are often in high power reconditioned vehicles. Reduce the heat from the engine through the fast air flow on the hood.
As for the upward branch, current market modified parts are mainly focused on modeling, but not practical in the efficiency of air supply.

Some racing cars have flattening technology applied chassis, whereby the chassis airflow faster than airflow in the body, could form a vortex as it passes up the rear bumper, and it does have a negative impact on the race car because the car needs a downward pressure on the back. In order to compensate this vortex, bypass extends rearwardly and could extend chassis guide air flow away from the rear, thus eliminating the impact at the rear.
