· 2 sourcesJapanese engineers have successfully completed a ground combustion test of a ramjet engine designed for a Mach‑5 hypersonic aircraft, Hacker News reported. The test was conducted by JAXA in collaboration with Waseda University, the University of Tokyo, and Keio University at JAXA's Kakuda Space Center, where the engine reached 1,832°F, according to bsky. Both sources noted that this breakthrough could potentially reduce flight times between Japan and the US to approximately two hours.
Baker's choice. Dense with flavour, light on filler.
Summary
Japanese engineers have successfully completed a ground combustion trial of a ramjet engine designed for a Mach‑5 hypersonic aircraft. This breakthrough could potentially reduce flight times between Japan and the US to just two hours, making long-haul supersonic travel a near-term reality rather than science fiction.
