Staged combustion control design for aero engines

This paper discusses the findings of an analysis of an aero engine staged combustion fuel distribution control system design in the framework of the LECCAGT research project. The paper outlines the motivation for developing a staged combustion system and highlights the control-related issues of such an approach for a civil aerospace application. Findings of an analysis of the emission minimisation are presented and control-related issues of optimal fuel distribution are addressed in the paper. Multi-objective genetic algorithms are implemented for the automation of the engine fuel distribution optimisation. Bumpless transfer techniques for priming and purging of burner stages during transient manoeuvres are analysed and presented.
