Souls world is mankind's most valuable asset, bionics help designers continue to break the speed limit of the weight and firmness , which allows for the study of shark skin swimmers get faster speeds. Although under the provisions of FINA , the major world competitions have banned the use of "shark skin" , but this technique can still play a role in other areas.

Fraunhofer Institute for Production Technology and Applied Materials, 18, ​​said that the researchers have developed a fake shark skin surface coatings can significantly improve the aerodynamic performance of wind turbine blades , thereby enhancing the efficiency of power generation reduce noise.

The researchers said the shark swimming along the direction of the epidermis ordered a trench -like structure , the scientists believe that this structure can reduce skin friction drag in turbulent flow . Fraunhofer Institute for Production Technology and Applied Materials developed by experts in their imitation shark skin coating , laying tested on a wind fan motor , confirm that the coating can be improved blade lift-drag ratio more than 30 %. Lift-drag ratio is the ratio of lift and drag of the aircraft , the higher the lift-drag ratio , the better its aerodynamic performance .

The researchers added that this could replace conventional coatings imitation shark skin coating does not increase the weight of the wind turbine blades , which can improve the efficiency of power generation , the current estimated annual output of a wind motor to improve 5-6% , and can reduce noise.
