The paper proposes an algorithm to prepare a design technological solution for the aerodynamic rudder of an unmanned aerial vehicle. The formation process of the rudder design technological solution includes the refinement stage taking into account the technological limitations. The algorithm is based on application of the topological optimization method for the case of maximizing the rudder structure static rigidity with the volume limitation. The structure of the finite element model for optimization was proposed, and the boundary conditions and parameters of the design flight mode were determined. Topological optimization resulted in obtaining a rudder power frame with minimum mass for the given design case. To verify the research, parameters of the stress-strain state were determined, and flutter for typical and optimized rudder design was calculated. Based on the optimization results, a structure was designed that met technological limitations and requirements in strength and aeroelastic stability.
