One of the most intriguing technologies of today’s auto world is still active aerodynamics. It is widely used by Porsche and there are a lot of questions about its principles. So we are going to shed some light on this topic and explain how exactly active aerodynamics works.
To put it briefly use of active aerodynamics technologies pursuits two goals. One of them is to increase the level of fuel efficiency. Another one focuses on improving the very performance of the car which uses this technology. Let’s take an in-depth insight into these processes.
In the view of improving fuel efficiency by the means of active aerodynamics, many cars are equipped with grill shutters. Efficiency is achieved through the ability of shutters to get closed any time it is possible. It influences the air flow itself. So that, when shutters are closed air, does not go through the very engine. On the contrary, it covers the body of a car and this is what makes the aspect of aerodynamics better. However, shutters get opened in case the engine of the car warms up and needs cooling off. Imagine how high the density of air flow at this moment is and it has a much higher cooling effect. Then the circle repeats itself. The shutters get closed when the engine temperature is decreased and the air is being accumulated again to kick in in a right moment. You may find it surprising but active aerodynamics grille shutters can save you from 0.5% to 1% of fuel consumption.
It is mostly cars with high performance that use technologies of such type. This process is not that new in fact. Autos of this type usually have rear or lower wings raised automatically when the speed is really high. However, some autos have a tendency to make use of rear wings for slowing downing purposes when braking. Nevertheless, some of the models do not use a power unit to control aerodynamics process. Some models interact with the air itself. Thus they tend to some parts of the body. It allows them to direct an air path.
What is more, the latest generation of supercars develops the idea of active aerodynamics technology. Thus, some of the autos used in everyday traffic are equipped with DRS known as drag reduction system. If you are unfamiliar with it, this the technology used by Formula 1 models. It gives you an opportunity to decrease the level of drag caused by rear wing. Usually, it can be controlled by a special button found on the steering wheel. Individual wings are used for some cars still. Their function is to act as flaps of an airplane.
