The Compressor

 There are two main styles for turbine compressors: the axial and the centrifugal.

Misc. Compressor Stuff

        HP = Cp x (T2-T1) x Wa x 1.414
Where Cp is the specific heat of air, (T2-T1) is the change in temperature across the compressor, and Wa is the airflow through the compressor in pounds /sec.
A typical example is the JT-9 used on 747's.
HP = .24 x 670(deg F) x 247(lbs/sec) x 1.414
HP = 56160 horsepower, assuming 100 percent efficiency
