Riblets and Sports
In top level sports fractions of a second decide between victory and defeat. The human body is limited in its performance and the athletes often get to their limits. With the help of bionic surfaces it is possible to improve the performance of the athletes with the same power input. Microstructured surfaces reduce the drag of different surfaces in the air and in water and are able to improve the overall performance of the athlete.
Another potential field of use is in bob sledding, where several tests are taking place at the moment. As high speeds and an ideal aerodynamic design are playing important roles in bob sledding, it is possible that through the application of riblets on the bob sleight a reduction in the power demand is possible.
In most of the sports where speed and aerodynamic design count, riblets could be used to reduce the power demand and furthermore increase the speed and performance. As a result the athletes have a lead over their competitors and are therefore more successful.
