The White Tornado
Interesting book by an ex Rolls-Royce engineer Jim Quinn. He describes the very interesting deliberations about the engine design for the MRCA/Tornado.
He was an advocate of a lower risk 2 spool configuration, the proposed Bristol Siddley BS143 compared with the eventual 3 spool RB199.
Lots of very interesting background.
R-R was of course very keen that the new, highly advanced military engine should follow the 3 spool configuration. But, a military engine with a relatively high bypass ratio and a massive reheat boost was and still is hugely different to a civil engine operation.
For those interested in gas turbines, well worth a read.
The author covers a wide range of topics other than just jet engines.
