1- for the compressor stage:
the main function of compresstion stage to raise the pressure and the temperature of the fresh air entering the engine.
the compressor stage consistes of the following :
- convergent divergent nozzle which generate natural draft for the incoming air .
- compressorwheel which accelerate the air into acertain speed .
3-The diffuser which converts the speed of the air into pressure (Energy Equation)
every two blades of the diffuser are shaped into divergent - convergent nozzle which raises the pressure of air .
