Scramjet 'flies' in Australia

Scramjet 'flies' in Australia


Scientists are not quite sure what happened after launch

A revolutionary new rocket engine capable of flying at over seven times the speed of sound has been launched for the first time in Australia.

The HyShot scramjet engine was fired on the back of a rocket from the Woomera Protected Area, a testing ground north of the southern city of Adelaide.

But the Australian scientists were unable to say on Tuesday if the scramjet had at any point flown under its own power. Project spokesman Peter McCutcheon said: "We're still analysing data... we're not sure, yet, if it was successful."


The scramjet needs
to reach Mach 5
to start working

Scramjet mission profile

If the experiment was successful, the scramjet would have started to work under its own power for just a few seconds before the rocket returned to Earth. The scientists will be looking at their data on the way the rocket behaved during these crucial few seconds to decide whether or not the scramjet worked. They hope to make an announcement on Wednesday. Experts say scramjet technology has the potential to reduce the flying time from London to Sydney to two hours, and substantially cut the cost of space launches.

Traditional approach

"We've bought a lot of bits and pieces off the shelf from automotive shops"

Scramjets are simple in theory; they have no moving parts and grab the oxygen needed to combust fuel from the atmosphere. That makes them more efficient than conventional rocket motors, which carry their own oxygen supply on board, adding weight and cutting the potential payload. But the big problem is that scramjets only start to work at speeds greater than five times the speed of sound, or Mach 5. A few weeks ago, the Defense Advanced Research Projects Agency in the United States launched a scramjet from a gun. The Americans say their experimental engine flew under its own power for a fraction of a second - a world first. A Nasa scramjet test in June failed when the missile that was intended to bring the engine up to its operating speed went off course.


The university has been working on scramjets for 16 years

The engine tested at Woomera was built by an international consortium led by researchers at the University of Queensland and is jokingly referred to as a "scroungejet".

"Ours is a low-cost alternative, and we've had to develop all sorts of ancillary equipment on the cheap," said Allan Paull, project head at the university.

Er, technically by definition a scramjet (supersonic combustion ramjet) is not a "rocket."

I wish them luck. One nation on the planet should have a space program.

Better "us", than an "Islamic" "Space program!!"

At LEAST, we'll "share the data!"

,,, and Indonesia can suck on the payload!

Oh, sure we're interested in London-Sydney in 2 hours. But first there's a little problem in Iraq.....

Highjack this....

I hope they have a better flight plan than the one shown in the con-trail picture.

Looks like one of the booster rockets off the Challenger...

Obviously written by someone who has never done the Kangaroo hop, nor Perth to New York.

No, I never have. I know it'd be cool if that would work out. But I'm quite sure that the military possibilities are far more interesting. Seven times the speed of sound, and no need to put oxygen in the payload, means you can add payload weight. That means better missiles, and maybe even--RAPID troop deployment? WHEW!

Yep! the next one will reach Bahgdad!(We might even put a nuke in the warhead.) 8-)
