Controller and Engine Simulation Implementation

Abstract

The rigorous performance demands made upon military gas turbine engines present the designer with a highly complex control problem. In order to gain an understanding of the problems involved this Chapter introduces and explains the relevant gas turbine terminology which will be used in subsequent Chapters. It sets out to explain in simple terms how a gas turbine operates, introducing the main engine components, the compressor, the combustion chamber and the turbine. Attention is then turned to consideration of the high bypass turbofan engine and controller simulations which are used throughout this work. An insight into the operational requirements and control problems associated with gas turbines is given. These cover the whole range of engine operation from engine start-up to normal operation and to operation with reheat.
