scramjet

A scramjet is a type of jet engine designed for hypersonic speeds, typically above Mach 5. Unlike traditional engines, it compresses incoming air using its high speed, eliminating the need for bulky turbines or compressors. The air remains supersonic within the engine, enabling the craft to reach extremely high velocities efficiently. Scramjets are useful for space launch and rapid travel, but they require to be moving very fast before they can operate effectively, often needing to be boosted to high speeds first. They represent advanced propulsion technology for exploring faster transportation methods.
