China Claims New Jet Engine Can Hit Mach 6 Without Changing Modes
China’s state‑backed researchers say they have built a contra‑rotary ramjet engine that can accelerate a aircraft from take‑off to Mach 6 without switching between turbojet and ramjet modes. The prototype has been experimentally verified, marking the first public claim of a single‑stage hypersonic engine. The design relies on low‑ and high‑pressure turbine blades rotating in opposite directions to manage airflow at extreme speeds. Material durability and heat‑resistance remain the chief hurdles before operational deployment.
