ramjet

A ramjet is a type of jet engine that operates efficiently at high speeds, typically supersonic or hypersonic. It works by taking in incoming air as it moves forward, compressing it naturally due to the high speed, then mixing it with fuel and igniting the mixture. The combustion produces a high-pressure exhaust that pushes the aircraft forward. Unlike traditional engines, ramjets have no moving parts such as turbines or compressors; they rely solely on the aircraft's speed to compress the air, making them simple and effective for very fast travel but ineffective at low speeds.
