Low Pressure Turbine vs. High Pressure Turbine
Hello!
I have a general question regarding about the number of stages in Low Pressure Turbine (LPT) and High Pressure Turbine (HPT).
Why are there more number of stages in LPT than HPT?
As an example, General Electric CF34 Engine, there are:
1 stage of Low Pressure Compressor (FAN)
10 stages of High Pressure Compressor
4 stages of Low Pressure Turbine
2 stages of High Pressure Turbine
Can anyone explain why LPT have more stages than HPT?
Thank you.
