Airplane engines are powerful machines that help planes fly by generating thrust. There are two main types of engines: jet engines and propeller engines. Jet engines work by sucking in air, compressing it, mixing it with fuel, and igniting the mixture to produce a high-speed exhaust that pushes the plane forward. On the other hand, propeller engines use a rotating blade to create lift and thrust. These engines are often found in smaller planes. Both types of engines are essential for air travel, allowing us to reach distant places quickly and efficiently.
