If I'm not mistaken, the vertical spoilers on the roof are there to prevent lift in the event the car gets sideways at speed. 156.073 mph. Fuel consumption figures not provided http://www.gassavers.org/images/smilies/smile.gif |

Welcome to the site Fabrio ! |
thanks for your answer and for the welcome .Cd;)
|
not any application for turbolence or deviation of the airflow from lateral area at the top of roof?
|
Fantastic article Fabrio !
Thanks again for posting the link ! " what of tasks? " Can you be more specific ? |
I can try: upper the car the pressure is lower of lateral area (comprehensible?).
Causes this pressure difference, (in my mind), the air come from lateral at upper of car (probably little quote of air flux). This diverted flow is cause vortices and induced drag.....it is an ipotetical opinion and I whonder an opinion for this one. Similar case, is the deviaton flow from lateral at the car underbody thanks |
So what you are asking is if the air pressure on the top of the car is lower than the sides ( lateral area ) ?
And you are wondering if this is what is causing the vortices and induced drag behind the car ? Also, you are wondering about effect that the airflow has as it travels from the side of the car body and under the car ? Am I understanding correctly ? |
