Design of fixed wing unmanned aerial vehicle with predictive maintenance approach

In this study, the basic design of a fixed-wing unmanned aerial vehicle (UAV) and the predictive maintenance approach planned to be developed and sustained in line with the design were investigated. The geometry of the UAV was created using 3D design software. External flow analyses were performed on the designed geometry using the finite volume method. Based on the data obtained from the analyses, structural and layout design studies were carried out in accordance with the accepted external geometry. Subsequently, the mechanical behavior of the structural components was examined through appropriate analysis methods then software and a UAV design suitable for production and intended use was developed. According to obtained data UAV manufactured as a prototype using additive manufacturing application. Based on the results of the analyses, the placement of sensors and control equipment on the control surfaces and the aircraft body was proposed in terms of location. As a result, the structural and mechanical behaviors of the UAV under the loads expected throughout its service life were predicted then necessary evaluations were made. Depending on these evaluations, potential structural and mechanical problems on the components were predicted and the required maintenance types and intervals were reviewed from a predictive maintenance and maintainability perspective. Based on the conducted study and the obtained data, improvements in maintenance intervals, maintenance procedures, and maintenance personnel costs were projected in accordance with the expected operational behavior of the UAV throughout its service life.
