China has just developed a cutting-edge Pulse Detonation Engine (PDE) for rockets 🚀 This game-changing tech uses rapid detonations to generate thrust, offering more power and efficiency than traditional engines 💥⚡. It could revolutionize space travel and speed up rocket launches 🛸✨. In December 2024, China also introduced a hybrid engine combining a ramjet with a rotating detonation engine (RDE), aiming to reach hypersonic speeds 🌍 🔥. This could make rockets fly faster and more efficiently
