Abstract
The Olympus 593 supersonic engine uses a two-spool turbojet with a simple reheat system for thrust boost. Control of engine fuel flow, primary nozzle area, and reheat fuel flow is largely electronic and the paper briefly describes principles of system operation before examining the function, location, and mounting of the constituent line replacement units. Procedures and equipment for checkout and fault diagnosis are described.
Maintenance philosophies and relevant test equipment were defined when the system performance requirements were specified and the case will be made that advances in maintainability techniques match the increased range of control system requirements, leading to utilization and “go” capability at least equal to best current experience.
