Chinese scientists claim to have made a breakthrough in rocket propulsion for stealth missiles, inspired by faults in the Boeing spacecraft last year.The technology uses helium injection to mix with fuel, enhancing efficiency and reducing the chances of a leak.The new rocket design can potentially change speed midair, making it harder to track or intercept.Researchers say the engine can generate over three times the thrust of using fuel alone.The engine's exhaust plume is claimed to be cooler, making missiles nearly invisible to early-warning systems.The technology could be applied to stealth weaponry and significantly lower the cost of sending rockets into space.The advancements may support China's satellite constellation project and plans for a moon base by 2035.China aims to launch reusable rockets and leverage new technology to reduce costs and achieve lunar ambitions.This technology could redefine modern warfare and space travel, with potential global implications.The helium injection idea could revolutionize rocket propulsion and aid in avoiding countermeasures.
