China tests hypersonic ramjet that reshapes airflow mid-flight

Chinese researchers have successfully conducted a ground test of a hypersonic ramjet engine capable of altering its internal shape during flight. This variable-geometry engine operated continuously from Mach 1.8 to Mach 6, a significant advancement as previous engines required separate boosters to reach ignition speeds. The breakthrough, detailed in the Journal of Propulsion Technology, utilized graphite seals and a rapidly adjusting combustion chamber throat to manage airflow at extreme temperatures and speeds. AI

    China conducts ground test of hypersonic ramjet that can change shape in flight

    At a test facility in China, a hypersonic engine that reshapes its internal airflow channel – much like a throat tightening and relaxing – has operated continuously from a relatively modest Mach 1.8 (nearly twice the speed of sound) all the way to Mach 6 without failing. And the …
