elloGov writes ""THE north African desert scorpion, Androctonus australis, is a hardy creature. Most animals that live in deserts dig burrows to protect themselves from the sand-laden wind. Not Androctonus. It usually toughs things out at the surface. Yet when the sand whips by at speeds that would strip paint away from steel, the scorpion is able to scurry off without apparent damage." Dr Han Zhiwu of Jilin University and colleagues have found that surface irregularity in aircraft design could substantially minimize atmospheric dust damage that aircrafts endure. What implications if at all significant would such design have on drag and lift?" Link to Original Source
