This study focuses on the comprehensive design and aerodynamic analysis of a fixed-wing unmanned aerial vehicle (UAV) specifically intended for search and rescue operations. The project begins with a thorough evaluation of critical design parameters, including dimensions and weight constraints, all aligned with established industry standards to ensure operational reliability and efficiency. Based on these preliminary assessments, theoretical calculations are performed to determine essential flight-related specifications such as flight endurance, wing span, wing profile, width, and overall height. Using SolidWorks software, a precise 3D model of the UAV is developed, translating the theoretical framework into a tangible design. Following the modeling phase, Computational Fluid Dynamics (CFD) simulations are conducted to analyze the UAV’s aerodynamic behavior, focusing on key parameters like lift, drag, moment, and thrust across various flight conditions. By integrating theoretical design, advanced 3D modeling, and CFD-based performance evaluation, the study aims to optimize the UAV’s aerodynamic efficiency, ensuring it meets the critical demands of search and rescue missions with enhanced stability, maneuverability, and endurance.
