How a 'shark skin' coating helps aircraft reduce emissions
As a transparent film is stuck onto the side of an aircraft fuselage in Sydney, Australia, sharks might not immediately come to mind.
But for Australian startup MicroTau, whose mission is to reduce global aviation emissions, aircraft and sharks go hand in hand.
Taking their inspiration from shark skin, MicroTau has developed an artificial shark skin-inspired, drag-reducing technology in the form of an adhesive film that can be applied onto the exterior of aircraft.
The Riblet Modification Package works on the same principles as the sandpaper-like surface of a shark’s skin that reduces drag, helping them move efficiently through water. These riblets align with the direction of flow — water flow for sharks, air flow for aircraft — thus reducing drag.
Stuck onto an aircraft, MicroTau's Riblet Film improves efficiency with less turbulence, reduces fuel emissions and thus potentially makes flights cheaper.
