When something is 'transonic,' it's moving at speeds around the speed of sound, like a plane pushing through the air. âī¸ It's in that awkward zone where some parts of the airflow are supersonic (faster than sound) and others are subsonic (slower than sound). This creates shock waves and makes things unstable. It's like trying to balance on a skateboard going downhill too fast. đš Think of it as the threshold between slow and super fast. đ¨
