| Abstract: |
Over the last two decades, technological transformation has resulted in a massively enriched supply of Unmanned Aerial Vehicles (UAVs); structural configuration is being hierarchically identified as the most decisive factor in determining both operational capability and mission efficiency. This review and meta-analysis studies the very basic theoretical design, development and structural analysis of the Delta shaped UAV, a special type of configuration that has been gaining increased attention for its unique aerodynamic and structural advantages [4]. The effective performance of delta wing configuration based on -specific changes to geometry, materials, and their portrayal across wind tunnel experiments is consolidated through systematic synthesis of 30 peer-reviewed sources across structural design methodologies, computational analysis methods, and experimental validation campaigns. The delta plan form, characterized by its characteristic swept-wing geometry and fuselage-integrated configuration, offers outstanding maneuverability and stability compared to more conventional UAV layouts. Higher aerodynamic efficiency is also achieved through specific surface treatments and stiffened structures, allowing for modifications. Literature survey documents improvements in lift to drag ratio of 15–30%, structural weight reductions of 20–25% and measurable improvements in maneuverability indices [5]. In this review, the most significant gaps in the literature is also identified and it includes limited research on fatigue behavior of composite structures under varying cyclic load and thermal stress distribution under extreme operating conditions and multi-objective optimization algorithms on FDM parts. So, what does the study mean for the future of delta UAVs Emerging technologies such as additive manufacturing, automated fiber placement, physics-informed neural networks, and structural health monitoring are identified as key enablers to help facilitate the next genera |
