Aircraft engines are powerful machines that provide the thrust needed for an aircraft to fly. They work by converting fuel into energy, which propels the aircraft forward. There are two main types of aircraft engines: jet engines and piston engines. Jet engines are commonly used in commercial airliners, while piston engines are often found in smaller planes. The efficiency and performance of an aircraft engine are crucial for safe and effective flight. Engineers design these engines to withstand extreme conditions, ensuring reliability and safety. Regular maintenance is essential to keep engines in optimal condition, allowing for smooth and efficient operation during flights.
