Fuel Control System of The GE4 Engine for The Supersonic Transport

The design of the power control and fuel systems for the augmented turbojet engine selected to power the United States supersonic transport combines proved designs with technical innovation to strike a design balance meeting all the requirements for commercial airline service. Application of the integrated three-variable power control principles long in production for supersonic military service will ensure a successful transition from the simpler, single-variable power controls operating at subsonic conditions in today's airlines. The overall power control system operation of the General Electric GE4 engine is presented followed by a more detailed account of the main and augmentation fuel and control subsystems. System design and component mechanization are shown and related to the factors that influenced the design.
