Japan has successfully conducted a ground combustion trial of a ramjet engine designed for Mach-5 hypersonic aircraft. This test, a collaboration between JAXA and several universities, is a significant step towards enabling flights from Tokyo to Los Angeles in under two hours. The engine, which has no moving parts and relies on forward motion to compress air, was tested under simulated high-altitude and high-speed conditions, validating its thermal-protection system and performance.
