Filing Flight Plan
Strap this on to your C172!!!
An experimental jet engine has been successfully tested at speeds of up to 6,835 miles per hour, or 10 times the speed of sound, during trials in Australia's outback, defense scientists said on Friday. The experimental air-breathing supersonic combustion engine--known as a scramjet engine--is being developed by Australian and U.S. defense scientists. Researchers hope it will lead to super-high-speed flight.
Scientists from Australia's defense Science and Technology Organization and the U.S. Defense Advanced Research Projects Agency (DARPA) used a conventional rocket to launch the scramjet high above the Woomera test site.
The engine was then tested as it reached speeds of Mach 10.
A scramjet needs a rocket to propel the vehicle to high speed before the engine, which requires supersonic airflow to operate properly, can take over. It also needs to operate in the thin atmosphere far above the altitude of commercial airliners.
"All the indications are it was a success, and we have some very happy scientists," an Australian defense spokesman told Reuters on Friday.
Flight data will be examined over coming weeks and compared to ground tests conducted in the United States, DARPA chief researcher Steven Walker said in a statement.
"We are pleased with this joint effort between the U.S. and Australia and believe that a hypersonic airplane could be a reality in the not-too-distant future," Walker said.
Scientists say the scramjet engine could lead to high-speed flights on long-range missions, as well as new, low-cost ways to launch satellites into space.
