What s going on with the shock wave of the plane,

The airplane tells the flight compressed air... Make the air denser... It is not the same as the air pressure around it, it will produce **... This is commonly known as the shockwave.

When an airplane travels at a speed of more than 330 meters per second, the "sound barrier" is broken, accompanied by a shock wave that travels through the atmosphere and produces a sound "**".

Sonic boom, the noise produced by the shock wave of a supersonic aircraft. Due to the pressure of the atmosphere, the speed and direction of sound wave propagation are changing rapidly, when the sound wave hits the ground, it produces a unique and huge popping sound.

Your question can look like this:

The so-called shock wave is actually generated by a sonic boom, which can be referred to the answers of the 2 people upstairs.

"Shock waves" can not be generated at any time, the aircraft must break through the speed of sound to generate, in actual flight, the speed of sound has a strict altitude limit, if it is below 2000m supersonic speed, the ground buildings and creatures will be damaged to varying degrees.

If the plane is ultra-low and supersonic at super-high altitude, then the pilot will die, hehe. It's just something that can be seen in the movies.

Shock waves are also known as shock waves.

Refers to certain physical quantities generated in the flow field when supersonic air flow is contracted, blocked, or when an object (such as a high-speed aircraft) moves in the air at transonic or supersonic speed.

Discontinuous surfaces with sudden jumps. It is a thin layer of compressed air with an actual thickness of almost more than 1 m. Necessary conditions for the formation of shock waves.

The relative velocity of the incoming stream must exceed the speed of sound. Shock waves, mainly in fluids at speeds higher than the speed of sound.

The velocity of the propagation and the stool exerts a compressive effect on the fluid of the wave. Shock waves are most pronounced in gases, where there is a thin wave front separating the compressed gas from the uncompressed gas. The pressure at the front and back of this wave front is different and has an abrupt change.

The greater this pressure ratio, the stronger the shock wave.

When the aircraft is flying close to the speed of sound, the local airflow velocity on the upper surface of the wing will exceed the speed of sound, which will cause a shock wave to occur, causing the airflow behind the shock wave to separate, causing a sharp increase in the drag of the aircraft.

When an aircraft flies at supersonic speed, the nose, wings, fuselage, tail, etc. will cause a sharp pressure change in the surrounding air, resulting in strong front and rear shock waves. The elapsed time interval between the two shock waves before and after is about seconds. If the flight altitude of the aircraft.

It's not too high, and we can hear thunder like a thunderbolt on a sunny day or a sound like a cannonball** at the moment when the shock wave passes, which is a supersonic aircraft.

The so-called "pop" in flight. Since there are two shock waves before and after, we are able to hear a short two-tone pop.
