摘要

U.S. and Australian researchers say a rocket-boosted, hydrocarbon-fueled sc-ramjet successfully operated for around 12 sec. while accelerating to Mach 8 from Mach 6.5 during a May 1 test from the Pacific Missile Range Facility in Hawaii. The flight was the fourth of 10 planned under the Hypersonic International Flight Research Experiment (HIFire) program, started in 2006 to develop technology for long duration scramjet flight at Mach 8. Given that the vehicle reportedly reached an altitude of around 100,000 ft. and clocked up a test time of 12 sec, versus the 8 sec. originally expected, it appears the experiment went better than anticipated.
