Abstract

The increasing environmental impact of fossil fuel usage has propelled a sense of urgency to address depletion concerns and environmental consequences. This article explores the potential of solar-powered unmanned aerial vehicles (UAVs) as a sustainable alternative in the aviation sector. Originating from advancements in photovoltaic (PV) technology, the integration of solar cells onto aircraft structures has led to innovations in electric aircraft, with a focus on UAVs. The study searchs the conceptual design methodology, emphasizing the complex interplay of factors such as aerodynamics, structural analysis, and performance requirements in solar UAV design. The selection and analysis of solar cells, energy storage systems, and their integration into the UAV are detailed. The study further discusses the crucial aspects of solar irradiation, weight analysis, and aerodynamic parameters in the design process. The proposed UAV design incorporates monocrystalline silicon solar cells, lithium batteries, and Maximum Power Point Tracking (MPPT) technology. A constraint analysis aids in optimizing power-to-weight ratios, thrust-to-weight ratios, and wing loading. The article concludes with a detailed weight estimation, aerodynamic parameters, and a conceptual design that envisions a solar-powered UAV capable of sustained flight. The outlined approach provides insights for future enhancements in solar-powered UAV technology, addressing challenges and contributing to the evolution of eco-friendly aviation solutions.
