Jet Engine theory books
Can anyone suggest a good jet engine or gas turbine theory book? I'm not thinking a basic book, but one at the intermediate to advanced level, probably undergraduate, with formulas, technical explanations and drawings, but not really of the pictorial nature.
In the past, I've heard that Rolls Royce put a good one out, and more specifically, I've seem to remember Pratt and Whitney had one called "Gas Turbine Engine", but I don't know if either is of the detail I'm interested.
Can anyone provide titles/authors of one(s) they like?
