Mini jet engine

The major components of the engine are a) Shaft b)Turbine c)Compressor d)Diffuser e)Nozzle guide vane f)Shaft tunnel g)Annular combustion chamber h)Exhaust nozzle i)Bearings j)Burner. Shaft-The turbine and compressor are attached to the shaft and form the rotary components of the engine. Turbine converts the energy in the burnt gases to rotary motion. Compressor-Sucks and compresses the air to the required pressure needed for combustion. DiffuserFurther increases the pressure of the flowing air to the combustion chamber. Nozzle guide vanes-Guides the heated gases towards the turbine blades. Shaft tunnel-The shaft rotates within this component. Annular combustion chamberThe combustion of gases takes place here. The air enters through the passages (holes) provided on the chamber in three zones. Exhaust nozzle-The burnt out fuel air mixture from the turbine flows out through this nozzle. This further increases the thrust output of the engine. Bearings-The shaft is supported on the bearings. Burner-The fuel is introduced into the combustion chamber by these burners. There are six reverse flow burners meaning the fuel is introduced into the chamber against the flow of compressed air. A few major dimensions are mentioned below:
