- Definição1
- A pressure wave formed in the air as an object, such as a flight vehicle, passes through the air at a speed greater than the speed at which sound can travel. As the vehicle moves through the air, it creates disturbances, and sound waves spread out in all directions from the disturbance. Since the vehicle is flying faster than the sound waves are moving, they build up and form a shock wave at the front and the rear of the vehicle. As air passes through a shock wave, it slows down and its static pressure increases. The energy in the air is decreased.
