An aero engine is a type of engine specifically designed to propel aircraft. It converts fuel into mechanical energy, generating thrust to lift and move the aircraft through the air. There are two main types of aero engines: jet engines and piston engines. Jet engines are commonly used in commercial airliners, while piston engines are often found in smaller aircraft. Aero engines operate on principles of aerodynamics and thermodynamics. They draw in air, compress it, mix it with fuel, and ignite the mixture to produce high-speed exhaust gases. This process creates thrust, allowing the aircraft to take off, fly, and land efficiently.
