Modern jet engines are among the most reliable machines ever built. Their primary purpose is to produce thrust, which moves the aircraft forward through the air.

A jet engine works by drawing in air, compressing it, mixing it with fuel, and igniting the mixture. The resulting high-energy gases expand rapidly and exit the engine, creating the force needed to propel the aircraft.

Today's airliner engines are designed for efficiency, safety, and environmental performance. They allow aircraft to travel long distances while carrying hundreds of passengers comfortably and reliably around the world.
