Ideal Cx factor

air resistance cxWhat shape should the car body be?, so that the Cx coefficient is as low as possible?
– This is the basic problem of car builders. We know, what shape is optimal: inverted o 90 degrees of falling water drop, can be approximately said, That …

Air drag coefficient Cx

The Cx coefficient is more and more often provided by designers of new cars, to emphasize how streamlined they are. Cx is dimensionless, its value in new, aerodynamic cars is below 0,30.
It must be emphasized, that air resistance has a decisive influence on …
