Current study is dedicated to the evaluation of the topology optimization method for the design of load-bearing aerospace structures. The subject of research was composite spacecraft attach fitting (adapter) which provides the interface between a spacecraft and a commercial launcher. Modelling of stress-strain state of the lattice payload adapter under operation conditions was performed. Compression strengths of structural ribs were defined together with the stiffness and buckling stability taken as the design constrains. By means of the topology optimization procedure optimal material distribution in the payload adapter was obtained. The workability of the adapter was proved by the confirmatory analysis.
