Slashdot: First Ever Scramjet Reaches Mach 10
A group of US and Australian scientists successfully tested a supersonic scramjet engine in the Australian Outback on Friday. The Sydney Morning Herald reports that a rocket carrying the engine reached mach 10, and climbed to an altitude of 330 miles before the apparatus re-entered the Earth’s atmosphere. “Australia’s Defense Science and Technology Organization (DSTO) said it was believed to be the first time a scramjet had been ignited within the Earth’s atmosphere … Scramjets are supersonic combustion engines that use oxygen from the atmosphere for fuel, making them lighter and faster than fuel carrying rockets. Scientists hope that one day a scramjet aircraft fired into space could cut traveling time from Sydney to London to as little as two hours.”
