Rather than being completely smooth, shark skin is unique in its ability to minimize drag through specific grooves, which, in aviation terms, allows for a smoother and more efficient flight.
AeroSHARK replicates this hydrodynamic property on aircraft. It is a “special film” made up of “tiny 50-micrometre riblets that reduce aerodynamic drag during flight.”
Great news, this should be widely adopted!
That website however…
