Abstract

The presentation reports on results of a conceptual design phase of a collaborative research programme aiming at the development of manufacture-optimized lattice fuselage structures satisfying fundamental requirements of airworthiness. It will be shown how topology optimization was used to analyse different load cases and maximize the stiffness of the fuselage barrel, which was done by University of Leeds. As result it will be presented what efficient pattern of ribs could be identified to carry given sets of loads. Adding buckling criteria to the structural analysis and manufacturing demands DLR will show a pattern of the reinforcement stiffeners which has been established to provide a backing to the specific choice of the preliminary design concept. As result an innovative airframe concept will be presented with high function integration, high damage resistance capability and under consideration of actual airworthiness requirements and demands.
