In a jet combustor, the air is mixed with fuel and the air is ignited. There are as many as 20 nozzles to spray fuel into the airstream. The mixture of air and fuel then catches fire and provide a high temperature, high-energy airflow. The fuel burns with the oxygen in the compressed air, to produce hot expanding gases. And the inside of the combustor is made of ceramic materials to produce a heat-resistant chamber. The heat can reach as high as 2700°C.

The high-energy airflow from the combustor goes into the turbine, making the turbine blades rotate. The turbines are linked by a shaft to turn the blades in the compressor and to spin the intake fan at the front. This rotation takes some energy from the high-energy flow which is used to drive the fan and the compressor DLLA138S1191. The gases produced in the combustion chamber move through the turbine and spin the blades. The turbines of the jet spin around thousands of times. They are fixed on shafts that have several sets of ball-bearing in among them.

The nozzle is the exhaust duct of the jet engine. This is the jet engine part that actually produces the thrust for the plane. The energy depleted airflow passing the turbine, apart from the colder air which bypassed the engine core, produces a force when exiting the nozzle acting to propel the engine, and thus the airplane move forward. The combination of the hot air and cold air are expelled and produce an exhaust producing a forward thrust. The nozzle 8N7005 may be preceded by a mixer combining the high temperature air coming from the jet engine core with the lower temperature air which was bypassed in the fan. The mixer helps to make the jet engine quieter.

When all the above steps are finished, the plane will advance smoothly in the air. And as you can see from the above, the nozzle does play an important role in a jet combustor.
