Abstract

This paper presents an overview of the modelling and simulation activities conducted in support of the operation of the engine systems validation rig (ESVR) demonstrator that is being developed as part of the power optimised aircraft (POA) project. The application of the more-electric concept to a civil aircraft engine as part of this project is described, outlining the expected benefits and anticipated challenges. The paper then identifies the importance of network-level transient modelling and simulation to the development of such complex systems and outlines the manner in which it has been used to support the development of the ESVR demonstrator. Key findings from the simulation work are then presented and discussed before the paper addresses some of the fundamental design and operational issues that must be overcome before the full potential of the more-electric aircraft concept can be realised.
