Roof Lip Aerodynamics

In this newest episode we look at the new fad aerodynamic device for your car the roof visor spoiler.

Roof lip aerodynamics.

These devices are often marketed by companies as aero. The rear view presents the contoured rear hatch spoiler and the add on lip for the cayenne s roof spoiler. The roof models were made on a scale of 1. If a spoiler s primary function is to provide downforce it will be tilted at a more vertical angle.

It has subsequently been improved and in its current incarnation uses nine 0 85 m 2 cross section axial flow fans to direct air into a settling chamber which in turn feeds a circular nozzle the exit of which is controlled by a set of eight flaps. Another aero benefit of a hard top is the rear roof trunk lid junction is smoothed out and moved rearward which also helps the airflow to a wing or deck lid. Airflow through the front end and roof. Roof spoiler rear hatch spoiler and diffusor.

In cars such as the a8 which are used predominantly for long distance travel aerodynamic drag also accounts for almost half of the running resistance. With a front end and roof designed to allow airflow the concept vehicle is given an even more exclusive appearance the efficiently aligned aerodynamics of the space saving sensation result in a drag coefficient of just 0 24. But smoothing the airflow has a slight detrimental effect of increasing the lift generated by the roof.

The powerful design of the rear apron incorporates a diffusor which makes a perfect surrounding for the techart sport exhaust system and its stainless titanium. 2009 is an impinging jet facility with a vertical circular downward jet of diameter d 1 m.

As such high velocity airflow coming off the roof toward the back of the vehicle will be disrupted reducing its velocity and creating the high pressure that results in downforce. From the wheels to the spoiler lips at the tail lights to the small corners that connect the roof. Volkswagen is pursuing new aerodynamic avenues with the id. 2a to obtain the local pressure values at different points on the roof surface each half of every model was instrumented with pressure taps at.

Aerodynamic drag plays an important role in customers driving behavior.
