Topology Optimisation of Aircraft Wing Box Ribs

Abstract: This paper considers the application of conventional energy based topology optimization methods for design of aircraft wing box ribs. Compared to standard topology optimization work undertaken at Airbus, the topology optimization of wing box ribs posed several additional challenges, mainly due to the wing box ribs being embedded in a redundant wing box structure. Several approaches to solving this problem have been investigated and are being reported as part of this paper, including a global analysis/optimizat… Show more

“…This includes successful aerospace applications during development of the new generation airliners such as A380, 350 and B787 (see, e.g., Krog et al 2004). However, the inability of taking fail-safe requirement into consideration in a computationally viable way has been seen as a significant limitation.…”

“…Topology optimisation allows a much wider search of the design domain since it is free from the limitations of a parametric definition. As such, it has been implemented in the redesign of many aerospace parts to decrease mass [7][8][9] . Ref.…”

“…These problems require the use of body-fitted finiteelement meshes, which are typically non-uniform and non-rectilinear. Such problems have been solved successfully by SIMP researchers on a number of occasions [6,7,8,9]; however, they present a unique challenge for users of the level set method. The HamiltonJacobi equation, which is at the heart of the level set method, is solved on a uniform Cartesian grid, which typically coincides with the finite-element mesh.…”
