Breaking the Sound Barrier !

Breaking the Sound Barrier !

An interactive animation showing breaking the sound barrier causes a sonic boom. Varying the speed of the plane with the slider to observe the effect this has on the wavefronts.


•If the Mach Number is below 1, the flow velocity is lower than the speed of sound - and the speed is subsonic.
•If the Mach Number is 1, the flow velocity is lower than the speed of sound - and the speed is transonic.
•If the Mach Number is above 1, the flow velocity is higher than the speed of sound - and the speed is supersonic.

Subsonic and Supersonic speed


•If the mach number is < 1, the flow velocity is lower than the speed of sound - and the speed is subsonic.
•If the mach number is ~ 1, the flow velocity is approximately like the speed of sound - and the speed is transonic.
•If the mach number is > 1, the flow velocity is higher than the speed of sound - and the speed is supersonic.
•If the mach number is >> 1, the flow velocity is much higher than the speed of sound - and the speed is hypersonic.
