Abstract:

Ultra High Bi-pass Ratio Engines constitute one of the most cutting-edge architectures in propulsion research panorama. Fundamentally, their introduction is motivated by the need of reducing fuel consumptions. Most of research projects on this topic focus on solving the numerous aerodynamic, control and structural challenges deriving from concepts. In this work, structural issues will constitute the central focus. The present study is the result of a 6-month internship in Airbus Operations SAS (Toulouse, France). The project aims to explore possible solutions of the design of the airframe of such engines. For this purpose, Topology Optimization (TO) is adopted as main tool: it allows to find the optimal arrangement of masses in pre-sizing phases. In particular, TO is used when no knowledge (nor experience) on the possible designs is available. A numerical model is developed in commercial software Optistruct. All engine configurations and most flight operative conditions are included in numerical analysis. Several mathematical formulations are investigated, and corresponding results are analyzed and reported. The final goal is to acquire an understanding on architectural features improving existent propulsion airframe.
