Development of the approach of inner casing for combustion chamber design with the aim of weight reduction with preservation of reliability based on topology optimization

Abstract

Topological optimization is a type of optimization that allows to obtain the best variant of material distribution in a given design area for given loads and boundary conditions. The article presents the results of the application of topological optimization approaches for the improvement of the internal combustion chamber casing. The optimization is carried out taking into account the requirements of strength and stability of the structure. The work is done in two ways, using solid and shell models. The optimization results shows the distribution of thicknesses in the inner casing of the combustion chamber constructed of a solid model and conducted verification calculations of the optimized design. The advantages and disadvantages of both optimization methods, taking into account the complexity of manufacturing the obtained structures.
