nozzle

The nozzle is the exhaust Duct of the engine. The Energy depleted airflow that passed the turbine, in addition to the colder air that bypassed the engine core, produces a force when exiting the nozzle that acts to propel the engine, and therefore the airplane, forward. The combination of the hot air and the cold air are expelled and produce an exhaust which causes a forward thrust.
