Thought I'd share this.

You're probably familiar with the cone shaped clouds that form when a jet fighter breaks the sound barrier - now watch what you get when an Atlas rocket travels through the clouds at supersonic speed. Fascinating IMO.

That's pretty cool. Smile

Looks amazing Smile

How is it possible? Can anyoenj explain it?

McGherkin · 2012-04-14, 10:10

I'll try.

When travelling faster than the speed of sound, the rocket makes a shockwave as it hits the air in front of it - this shockwave is also where the sonic boom comes from.

The shockwaves spread out in a cone shape behind the rocket. When you see the clouds ripple, it's this cone shape of shockwaves passing through them.

Ooh, Ok.. How fast is sound? ;p

To break the sound-barrier.. 1000km/h. Mach1.

*Cough* Thats whats told me. Looked it up, and it seems to be 'a bit' faster:

Quote:The speed of sound is the distance travelled during a unit of time by a sound wave propagating through an elastic medium. In dry air at 20 °C (68 °F), the speed of sound is 343.2 metres per second (1,126 ft/s). This is 1,236 kilometres per hour (768 mph), or about one kilometer in three seconds or approximately one mile in five seconds.

Haha, Maybe good idea for a new car in LFS Tongue

Turbo Rocket TR28 ;p
