Vorbild Delfinhaut: Elastisches Material vermindert Reibungswiderstand bei Schiffen

(PresseBox) (Bremen, )
Für eine elegante und ökonomische Fortbewegung im Wasser geben Delfine den Wissenschaftlern ein exzellentes Vorbild. Die flinken Säuger erzielen erstaunliche Schwimmleistungen, deren Ursachen einerseits in der Körperform und andererseits in den elastischen Eigenschaften ihrer Haut zu finden sind. Letzteres Phänomen ist bereits seit Mitte des vorigen Jahrhunderts bekannt, konnte aber bislang nicht erfolgreich auf technische Anwendungen übertragen werden. Experten des Fraunhofer IFAM und der HSVA GmbH haben nun gemeinsam mit zwei weiteren Forschungspartnern eine Oberflächenbeschichtung entwickelt, die ähnlich wie die Delfinhaut den Strömungswiderstand im Wasser messbar verringert.

Delfine haben eine glatte Haut mit einer darunter liegenden dicken, nachgiebigen Speckschicht.
