JET ENGINES

The three most common types of jet engines are the turbojet, turboporp,
and turbofan.
Air entering a turbojet engine is compressed and passed into a combustion
chamber, oxidizing the fuel. Energy produced by the burning fuel spins the
turbine that drive the compressor, creating an effective power cycle.
turboprop engines are driven almost entirely by a propeller mounted in
front of the engine, deriving only 10 percent of their thrust from the exhaust jet.
Turbofans combine the hot air jet with by passed air from a fan, also driven by the turbine.
the use of by passed air create a quieter engine with greater boost at low speeds, making it a popular choice for commercial air planes.
