“…Furthermore, it is suitable for the early design stages and can provide quick preliminary results, serving as a validation method for the integrated design of the solar-powered UAV body and power system. In future research, further optimization of the solar-powered UAV's airframe can be conducted using computational fluid dynamics (CFD) methods [10][11][12][13][14][15], particularly in addressing complex fluid dynamics issues, including turbulence, three-dimensional flow, and multiphase flow [16]. In the preliminary design stage, it is essential to determine the overall parameters of the UAV, including wing area and flight speed, while considering the efficiency and characteristics of the energy management system.…”

The development of solar-powered unmanned aerial vehicles (UAVs) primarily focuses on enhancing the efficiency of the propulsion system to minimize energy consumption during the conversion of valuable solar energy. However, due to the unique nature of UAV propulsion systems, there is limited cross-reference ability among existing solar-powered UAV systems. This paper proposes an integrated design approach for the propulsion system and UAV structure. Based on this approach, an overall design is conducted for the solar-powered UAV, including initial design goals and performance parameters. Aerodynamic layout design and performance estimation are carried out, and a prototype is fabricated and assembled for flight testing validation. The results demonstrate the significant importance of this approach in improving the efficiency of the solar-powered UAV propulsion system.

“…Another approach is to use solar cells to power UAVs by harvesting energy from the outside and providing additional power that is dependent on the sun, weight, wing surface area, and efficiency [15][16][17]. Other research works were stirred on developing more efficient propellers as a viable approach [18][19][20][21][22]. One of the cheapest yet most effective approaches to considerably boost the endurance and performance of UAVs is to minimize the amount of fuel consumption required for flight operation through optimal trajectory planning [23][24][25][26].…”

This study describes the development of a novel numerical optimization framework to maximize the endurance of unmanned aerial vehicles (UAVs). We address the problem of numerically determining the optimal thrust and cruise angle of attack in a two-dimensional space for a UAV under certain initial, periodic, and bound constraints. The time horizon of the free final time optimal control problem (OCP) is first normalized, and the normalized OCP in integral form is discretized in physical space into a nonlinear programming problem (NLP) using Fourier collocation and quadrature based on equispaced points. Great attention in this work is placed on the accurate detection of jump discontinuities and resolving the thrust history effectively directly from the Fourier pseudospectral (FPS) data through a novel edge-detection method without any smoothing techniques. The numerical results demonstrate that the proposed method is simple, stable, and easy to implement.
