What is Shock Wave? | Understanding Supersonic Flow and Shock Wave Formation | Effects of Shock Wave

Hi. In this video we look at what is supersonic flow and the formation of shock waves when an aircraft flies at supersonic speed. We see what causes the shock wave to form and the types of shock waves.
We look at the aerodynamic changes that happen because of this shock wave, which is a major factor why almost all aircraft fly in subsonic speeds.
We also see some general design considerations for supersonic aircraft.
Hope its useful! Got Feedback!! Send it to [e-mail].

Most commercial planes fly within the transonic range near the speed of sound where the airflow is part subsonic and part supersonic. Modern fighters have to compromise between high supersonic speeds and subsonic cruising speeds because they can't fly at supersonic speeds for prolonged periods. Nearly all modern fighters not always but often cruise somewhat below the transonic range while only being able to reach supersonic speeds in short bursts. Sadly, planes that do indeed cruise at supersonic speeds don't fly anymore. The Concorde and SR-71 are examples that easily come to mind, but many early jet fighters like the F-104 and F-106 also flew supersonic as far as their range and fuel capacity could allow! Some advanced fighters like the F-22 can "supercruise" which means to faster than the speed of sound without the use of afterburners, this is misleading because though they could cruise faster than sound, it still isn't practical and thus are still very limited to how long they can fly at such speeds.

That is an awesome explanation! Thank you!

@@JxJAVIATION You're certainly welcome!

Don’t planes fly right below transonic for better efficiency😂

[@ChrisZoomER]

@@PaulJackson157 Some do, not all. I was told that first hand by a senior 777 pilot and other flight crew.

Why does the normal shock move back toward the trailing edge?

[@JxJAVIATION]

As the speed increases, the shock wave gets pushed rearward

[@rishis8714]

@@JxJAVIATIONshouldn't it move sideways? like in your profile picture?
