White paper: Topology optimization for mass reduction in aeronautical industry

In the current context, since Paris agreement on climate change, reduction of greenhouse gas emission has been a main issue for manufacturers in different industrial sectors and particularly in aeronautical sector. In order to address this new challenge, the improvement of part performance is crucial, especially the reduction of mass which allows to reduce gas emissions. Therefore, optimization allows to reduce effectively the mass of structural parts and tackle environmental issues. In this white paper are explained the interest of optimization and its set-up. In addition, different types of optimization are explained such as sizing optimization, shape optimization, topology optimization and materials optimization. A focus on topology optimization is done, especially on challenges and interests, limits and perspectives for the future.
