[QUOTE="Garycrow, post: 914899, member: 30743"] Yep. I realize the article is a hoax, but a lot of people don't realize that all the rules of aerodynamics change when going from subsonic (golf ball) to supersonic (bullet). Subsonic airflow can be modeled much as the flow of water because the air can be treated as an incompressible fluid. With supersonic airflow the rules all change because you throw compressibility into the equation. Just because dimples work on a golf ball, don't assume that they'll do the same thing on a bullet. There are a lot of design differences between supersonic and subsonic aircraft. The wings are shaped differently, the intake of the engines are different, and the tail is usually a stabilator setup on a supersonic airplane that offers more range of movement than the conventional stab/elevator setup. A friend flying a EA-6B accidentally got one supersonic one day. After he got it back under control and cleaned out his pants he said "never again". Lots of weird things happen when you get an object meant to be subsonic going above the speed of sound. [/QUOTE]
