Has the scram engine been fully tested and known to have been used regularly in service even?.Is there anything newer being developed, anyone know?.

AFAIK there were a number of interesting prototype air breathing engines in test at the moment.

I believe the scramjet holds the world record for airbreathing flight at mach 10+

That's a heck of a speed. I certainly have no desire to travel on anything that goes that fast. You'd almost be back before you left.

I know :diablo:

NASA flew a third version of the X-43A on November 16, 2004, achieving/maintaining a speed of Mach 9.68[2] at about 34,000 metres (112,000 ft) altitude [3] and further testing the ability of the vehicle to withstand the heat loads involved.[4]

This would be the one :)

I seem to remember seeing on TV, that the scram jet was only able to go so far up, as there was not enough air for the cobustion to be efficien
nt, and they were trying out another engine that didn't need air.

Not entirely sure - However the link speaks for itself

The small amount of O2 at the Operational hight of a scramjet would pall in comparison to the compression of the engine when scooping it up at mach 10 :diablo:

Bring it on, I'm sick of the 24hr+ Oz to UK. I'll gladly accept the discomfort for 2 hours.

I wonder how Qinetiq are getting on with their scramjet testing?
