At our local Science Centre, there is a demonstration of how the dimples on a golf ball decrease the wind resistance compared to a ball of the same size which is smooth. The fact that golfball maunfacturers spend gobs of dough developing new dimple patterns for different conditions and control, I have to believe that there is a strong effect on the aerodynamics from the dimples.
During the Olympics, I noticed a cycling helmet worn by a rider in the velodrome which had dimples running down the centre of the helmet. I assume that she was getting a benefit from the same principle as the golfball (perhaps to a lesser degree).
MY QUESTION: For automotive/aeronautical applications, would this not be a benefit? I realize that for the average car traveling at 30MPH, it may not make a significant difference, but for aircraft, and F1/Indy cars I would think that they should get better performance.
