Designing various-purpose subassemblies based on topological optimization

In recent decades, theory, algorithms and topological optimization technologies have been actively developing to solve problems in various fields. This technique is widely used and used in the design of subassemblies in engineering tasks. Of particular interest is the implementation of topological optimization methods in the aerospace industry. The main result of topological optimization is the determination of the effective distribution of material(s) in a part. The article provides an overview of recent developments related to the design of broad-purpose products, including for space and rocket technology based on topological optimization. The main algorithms for solving topological optimization problems are briefly listed. A separate emphasis in the review is placed on the opening qualitative new opportunities in modeling cellular and mesh structures, products from composite materials and multimaterials. Examples of topological optimization solutions that have already become classic are given. Many design results are closely related to the introduction of various modern additive manufacturing technologies. The review concludes with topical issues that will ensure future growth potential and prospects for the application of the entire range of design and additive production technologies in the aerospace industry.
