The adopted control philosophy is considered. The engine and its reheat and secondary nozzle systems are considered from a mechanical point of view, and the mechanical performance is evaluated as a function of the special aspects of supersonic flight. How the long hot soak at cruise, which sets the Olympus apart from all other engines, was obtained is considered by giving an overview of the engine on a modular and system basis that includes the following: compressor intake module, low pressure compressor module, intermediate casing and gear box modules, high pressure (HP) compressor module Olympus 593 stage 6 HP compressor peak temperature and stress range, combustion module, turbine modules, reheat system, secondary nozzle assemby, engine electrical system. It is concluded that the 600,000 hours of operational experience, over half at Mach 2.0, have shown that the adopted control philosophies were correct and are showing that the most significant difference between civil subsonic and supersonic engines is the cruise at high inlet air temperatures which has produced some unexpected mechanical affects.
