This is a NASA wind-tunnel test of an experimental plane design called the joined wing. Photo: Flying with less energy means flying more aerodynamically, and that means developing better plane and wing shapes. So what exactly is aerodynamics? Let's take a Science of aerodynamics, as it's known, we'd never be able toĭesign planes or spacecraft, land-speed record cars, orīridges that can survive hurricanes. We slice through it at speed is incredibly important: without the Although we're surrounded by this mysterious gas, and life is impossible without it, we hardlyĮver give it a moment's thought.
