Abstract:

Unmanned aerial vehicles (UAVs) with rotary wings, or hexacopters, have a wide range of possible uses in strategic, industrial, medical and defense settings. The design optimization of UAVs is a crucial task that significantly affects the application possibilities due to the tradeoff between flight duration and payload capacity. The core body frame is one of the structural components that make up the majority of the weight of a standard hexacopter. The present study on selecting a hexacopter drone proposed the best cross-section and material for static deformation and stress-induced for two different materials (PLA-CF and CFRP) and two different cross-sections of the arm (I and Hollow square). Dimensions are taken initially from the literature survey. Simulations are done using ANSYS for the literature drone and proposed drone. Topological optimization was also done on the drone arm for different cross-sections and different materials. Considering structural flexibility and stiffness as objective functions for selecting the best drone decision-making through a weighted decision matrix was adopted.
