A jet engine is a type of engine that propels aircraft by producing thrust. It works by sucking in air, compressing it, mixing it with fuel, and igniting the mixture. This process creates a high-speed stream of exhaust gases that pushes the aircraft forward. Jet engines are known for their efficiency and power, making them ideal for commercial and military planes. There are different types of jet engines, including turbojets, turbofans, and turboprops. Each type has its own design and purpose, but they all operate on the same basic principle of converting fuel into motion. Jet engines have revolutionized air travel, allowing planes to fly faster and farther than ever before.
