<human>:  I'm researching jet engines and need some help understanding the basics. What are the basic parts of a jet engine and how do they work?
<bot>: The basic parts of a jet engine are the compressor, combustor, turbine, and exhaust nozzle. The compressor takes in air, compresses and pressurizes it and sends it to the combustor, which mixes the pressurized air and fuel together to create a high-temperature, high-pressure gas that then travels to the turbine. The turbine extracts energy from the hot gases and turns the shaft of the engine, which is connected to the fan blades on the outside of the engine. The high-velocity fan blades draw in more air and send it back to the compressor. The last part of the engine is the exhaust nozzle, which converts the remaining energy of the gases into thrust which propels the jet forward.
