I wrote about this ages ago, in that shark skin is an evolutionary adaptation worth study because water is thicker than air, but when air compounds, blah blah blah. Basically think of making a composite mold with directional tiny tiny dorsal fin looking surface. If you rub your hand on it the wrong way it cuts you open. Could even be scaled for large cargo ship hulls.

Next up: my personal wing invention which uses leading edges modeled on humpback whale fins, because the use case / stall profile is better.

Sigh, I’m going to have a great time in Heaven chatting with Leonardo da Vinci…

From the featured article:

> This technology is fundamentally different from the “rivulet (shark skin) process,” which is known as a typical aerodynamic drag reduction technology. The rivulet process mimics the fine longitudinal grooves in shark skin, and by carving grooves approximately 0.1 mm wide along the direction of airflow, it aligns the vortices that occur near the wall surface of turbulent airflow areas. DMR, on the other hand, delays the switch from laminar to turbulent flow by means of random and minute irregularities. The flow zones it affects and the mechanisms it employs are based on completely different concepts.

>humpback whale fins

you might find this video interesting then, the fastest rc drone in the world and it uses humpback inspired props.

Why wait for heaven. There probably are mods for Kerbal Space Program with exactly that parts. Create your wingsuit there.
