This study focuses on designing and developing a fixed-wing unmanned aerial vehicle (UAV) to meet strict operational requirements while maximizing cargo capacity. The design must adhere to specific constraints, including a maximum wingspan of 80 inches and a structural weight limit of 5 kilograms. Achieving these goals involves a delicate balance between maintaining the UAV's structural integrity and ensuring its maneuverability, effectiveness, and ease of transportation. The challenge lies in maximizing the structural strength within these limits to ensure the UAV’s long-term reliability in field operations. The ultimate goal is to create a proficient and efficient UAV, utilizing resources and methods to optimize performance.
