Optimisation methodology for integrated equipment installation in new engine architecture nacelles

The development of new higher efficiency turbofan aero engines requires several design enhancements that typically result in shorter and slimmer nacelles. Consequently these engines provide less space for the engine systems installation and for maintenance accessibility. In the Novel Integration of Powerplant System Equipment project, optimisation methodologies are being investigated and developed for the integrated installation of equipment into the restricted volume of new architecture engines’ nacelles. The underlying optimisation methodology is built on a graph based approach involving efficient routing algorithms. Besides the methodology, also the software implementation and its application to engine equipment installation design cases are presented in this paper.
