It's so wierd to think that 2009 is only 3 years from now. I'm hoping they can get these dual mode scram jets mature enough to the point where we can start apllying them to service aircraft in the short term future,

I'm kind of sick and tired of these space planes getting X designations. Save the X for fighters! Pretty soon it'll be the X-138
The SCRAMJET technology is still in a nascent stage of development the world over. India is the second country after the U.S. to have advanced this far. "Other than the U.S., which has recently carried out in-flight demonstration of supersonic combustion for a short duration, work related to supersonic designs in other countries such as Japan, China, Russia, Australia, Europe and others are either in their initial or ground testing phase," ISRO said in a release. Through a series of ground tests, a stable supersonic combustion was demonstrated at the VSSC for nearly seven seconds with an inlet Mach number of six (six times the speed of sound), the release said.
It is learnt that an in-flight test SCRAMJET using a rocket was likely to take place in 2007. "In the coming years, ISRO is planning to flight test an integrated SCRAMJET propulsion system comprising air-intake, combustor and nozzle, by using a cost effective, two-stage RH-560 sounding rocket. Development of such a high technology system will come in a big way towards meeting the futuristic space transportation needs of our country." The cost of the current test was about 15 times lower than a similar test in the U.S.
Lab research indicates the engine, known as a scramjet, can propel an aircraft at more than five times the speed of sound. Researchers hope to fly five to eight unmanned X-51 As at speeds up to seven times the speed of sound, or about 4,600 mph.
Program Director Charles Brink said the goal is five to 10 minutes of scramjet-powered flight for a dash of up to 600 nautical miles.
