WebMay 19, 2009 · Supersonic flight is one of the four speeds of flight. They are called the regimes of flight. The regimes of flight are subsonic, transonic, supersonic and hypersonic. Vehicles that fly at supersonic speeds are flying faster than the speed of sound. The speed of sound is about 768 miles per hour (1,236 kilometers per hour) at sea level. Webaccount. So far, the calculation of the supersonic acoustic intensity has only been formulated on the basis of Fourier based NAH. The authors are inclined to think that the term “supersonic acoustic intensity” can be somewhat confusing, since it might lead to the misunderstanding that the energy in the sound field travels with supersonic speed. patronat antoni roig torredembarra https://korkmazmetehan.com
