In order to execute their designated missions, contemporary UAVs are required to possess elevated mechanical reliability. In order to accomplish this objective, it is necessary to select a load-bearing configuration, structural elements, and material that will ensure the stresses in these elements do not exceed their destructive limits under all possible loads. Furthermore, the drone must be designed in such a way that self-exciting vibrations do not occur, which would inevitably lead to the destruction of the structure. The analysis of strength involves the application of stress and strain calculation methods to classical force elements, including beams, rods, frames, plates, and shells.
