China’s magnesium-powered scramjet breakthrough nearly doubles thrust at Mach 6

Chinese researchers developed a new scramjet afterburner that nearly doubles thrust at Mach 6 and high altitudes by injecting magnesium powder into exhaust gases. This creates secondary combustion, boosting overall thrust by 86.6% in ground tests simulating Mach 6 conditions. The magnesium reacts with waste gases, improving efficiency. Challenges include even powder injection and potential engine damage from magnesium oxide crystals. If refined, this technology could enhance China's hypersonic capabilities for civilian and military use.
