| The material is moving highly supersonically and creates a shock wave ahead of it. |
|
| The channel expands supersonically into the surrounding air as a shock wave and creates an acoustic signal that is heard as thunder. |
|
| As you mention, a ramjet needs to fly supersonically, which a V1 flying bomb did not. |
|
| All those who flew on the aircraft were given a meal and champagne, plus a certificate to say that they had travelled supersonically. |
|
| It was realised in the 1950s, both from observations and from physical considerations, that this plasma must be supersonically expanding away from the Sun, and pervade the entire solar system. |
|
| On flight trials, it was proven to be amazing, flying supersonically on its third flight and eventually reaching Mach 1.89. It hit 1,000 miles per hour on its seventh test flight while climbing and still accelerating. |
|
| While the roar of jets has been dulled by quieter engines — and the retirement of the supersonically loud Concorde — people living beneath increasingly precise flight paths can feel as if they are under siege. |
|
| But he has now developed a way to do so. As the supersonically flowing condensate slows down it creates a second boundary at the point where its velocity becomes subsonic. |
|
| Released at 20,000 ft, the Tallboy would hit the ground supersonically, typically producing a crater 24 metres deep and 30 metres wide. |
|
| The M5 is supersonically fast, easy to drive fast and should be able to part you from your driving licence within the first few days of you owning it. |
