Compressors Flashcards
What is the primary function of a compressor?
To supply a sufficient air quantity for combustion chamber requirements
Where does the compressor get air from and where does it discharge it to?
Gets it from air inlet duct and discharges it to the combustion chamber
What is the secondary function of the compressor?
To supply systems requiring bleed air
What is the location of the bleed ports based on?
Pressure and temperature needed
What are the two main components of a compressor?
-compressor rotor
-compressor stator
Describe the compressor stator?
Fixed component with stator vanes to guide and slow airflow to increase pressure
What is the combo of a rotor and stator c@lled?
Compressor stage
What is a compressor stage?
A combination of stator & rotor
What are the two compressor types?
-centrifugal flow compressor
-axial flow compressor (for gas turbines)
What do centrifugal compressors consist of?
-impeller (rotor)
-diffuser (stator)
-compressor manifold
What is the pressure rise per stage Ona centrifugal compressor?
Around 8:1
How many stages are centrifugal compressors limited to and why?
2 due to efficiency concerns
