Aerodynamic optimization methods in the context of shape optimization are described. The problem of optimization of the shape of the nacelle support suspended under the wing of the UAV is presented. The methodology of the study assuming two optimization processes is comprehensively described. The first assumes optimization of the shape of the profile, while the second assumes optimization of the height of the cantilever. Two optimization methods were used, namely design of experiments and gradient optimization method. The optimization results of the two methods were compared and conclusions were drawn.

Introduction Introduction In the era of growing needs for unmanned aerial vehicles, optimization of their aerodynamic structure is becoming a key research issue. In order to increase the efficiency and reliability of the operation of these devices, it is necessary to develop an effective methodology for optimizing their design. 1 This work will discuss the concept of a methodology for optimizing the aerodynamic structure of unmanned aerial vehicles. The use of this method allows for fine-tuning the shape of the surface to meet the needs of a specific application, leading to improved aerodynamic properties and increased energy efficiency.
