The escaping air stream covers the side of the front wheels like a curtain thereby reducing aerodynamically unfavorable turbulence around the rotating wheels.
Bmw air curtain system.
Air curtain is machine used for separating outside environment with inside environment.
Air curtains has downward facing blower mounted over an opening.
Sources are telling us that this feature will play a key role in the development of future aerodynamic features on all bmws.
These oddly named aerodynamic features reduce turbulence and improve fuel economy by pulling in air.
This has a positive effect on efficiency and driving stability while also reducing the noise level in the cabin.
It throws air across the surface with certain pressure.
Many factors enter into considering installing an air curtain such as local environment what is going through the door.
Usually the opening is at the entrance to a building or opening between two areas having different temperatures.
They can be a great choice when an entryway has very high traffic as the door would constantly be opening and allowing conditioned air to leave.
Thanks to targeted aerodynamic measures such as air vent control the active rear spoiler or the air curtain in the front apron your bmw is able to achieve an optimised drag coefficient.
Good ideas don t always have to be complicated.
