Yes - I was fortunate to be given a copy in the late 70s.
It contains everything you are ever likely to want to know about jet engines, helped me through my CAA engines exam and I still refer to it occassionally. Clear text and great colour pictures.
I don't know its current price so whether it's worth buying for A/C Gen is a mute point. If your course material is 'light weight' then yes, but I should like to think only buy as a back-up.
