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
