Supersonic Transport Plan Stalls
Meanwhile, the Japanese effort to design a next-generation supersonic transport is struggling with setbacks and looking for international partners, The Associated Press reported on Monday. The Japan Aerospace Exploration Agency (JAXA) will enter talks next month with NASA to discuss cooperative efforts. Japan is working to develop a scramjet engine that would be 99 percent quieter than the Concorde, and Boeing would build the airframe, The Associated Press said, though those reports were deemed "premature" by JAXA. Japan does aim to have an experimental hypersonic transport flying by 2025. That aircraft would fly at Mach 5 and cross the Pacific within two hours, according to JAXA's online vision statement. Using liquid hydrogen as fuel, it would be efficient and environmentally friendly, JAXA says. The technology would also be useful for the first stage of space-transportation systems.
