Design and Fabrication of a Medium Size Uav with Smart Lock-System for Wings

This paper summarizes the entry of undergraduate students' team for a competition. The team was formed to design, build, test, and fly an Unmanned Aerial Vehicle while keeping in mind to ease the manufacturing and assembly processes capable of lifting heavy loads.The configuration of the aircraft was chosen based on low power to weight ratio and design constraints. To ensure the required aerodynamic forces are met and to distribute the landing impact loads better through the airframe, the CATIA V5, Airfoil section, and structural integrity of landing gear was analyzed using ANSYS 16.2 software. To reduce the unnecessary weight, the structure of the wing and fuselage section was examined. A smart locking system was designed and integrated with the structure to ease the assembly process and to ensure safe attachment of the wing to the fuselage.
