When was the last time that an aircraft carrying fare-paying passengers flew through the air faster than the speed of sound? Well, I'm sure you're all thinking of Concorde, which last flew in 2003, and you'd be right. But did you know that the last time you flew on an airliner, there was a very good chance that the aircraft you were flying in actually had supersonic air flowing over certain parts of the airframe. And that's because all modern airliners have something called a supercritical wing. Now, on a traditional wing, the top surface is highly cambered or curved, which results in air speeding up as it flows over it due to a phenomenon called Bernoulli's conservation of energy. Now, this is a vital part of how a wing generates lift. But as the aircraft fly closer to the speed of sound, this very vital part of the lift process actually begins to limit us. Now, imagine an ...
