Ramjet engine for Mach 5-speeding hypersonic aircraft tested at 1,832°F by Japan
SMRTR summary
Japan's space agency JAXA, working with three major universities, successfully tested a ramjet engine built for Mach 5 flight at temperatures reaching 1,832°F. The aircraft's heat shield kept internal systems running normally, bringing Japan closer to hypersonic planes that could fly Japan-to-U.S. routes in just two hours.
