The structure of the fish scales inspired engineers from Stuttgart, Germany and London to develop technology that would help increase aircraft speed. To do this, they paid attention to the underwater living world. The structure of the fish scales allows it to easily overcome water resistance.
This effect was replicated in an array of fish scales attached to a plate inside a laminar water tunnel at the University of Stuttgart. Engineers plan to install artificial grilles made of such “scales” to aerodynamic surfaces. In turn, this technology could give rise to the development of a new generation of aircraft. These machines will fly faster while using less fuel.
