The nozzle receives air coming from the turbine and turns the high pressure into high velocity. Because the velocity of the air leaving the engine is significantly higher than the velocity of the air around the engine, a force is created that pushes the engine forward. This forward force is called thrust. The amount of thrust that is produced by the engine can be found using the “thrust equation” shown below. Most turbine engines have a way to vary how much mass is leaving the nozzle and/or how quickly the air leaves the nozzle in order to change how much thrust is produced at a given time by the engine.
