Control Concepts for a High Bypass Aircraft Turbofan Engine

This paper examines the engine main fuel and geometry control design concepts and their relation to engine requirements for a large, high bypass, aircraft turbofan engine. This class of engine is representative of those powering the new “airbus” type aircraft which are currently under development. The functional design highlights of a simple, efficient, and compact control system are discussed and related to reliability, maintainability, and weight.
