For a college level book I would recommend J. Kerrebrock "Aircraft Engines and Gas Turbines", Second Edition.
Besides the usual Aerothermodynamics stuff it includes also engine structures and noise. It's available through amazon where you can read sample pages
The Pratt and RR books are very good but don't have equations and are only descriptive aimed perhaps to Aviation maintenance and operations personel jet engine familiarization courses.
Are the P&W "The Aircraft Gas Turbine Engine and it's Operation" and RR "The Jet Engine" books commercially available? I once got them through engine representatives but I don't have them anymore.
Thanks
