Abstract

This paper presents an overall scheme of a long-endurance small solar-powered convertible unmanned aerial vehicle (CUAV) that operates tilt-rotor for multiple hover tasks. First, a solar/battery hybrid energy strategy was proposed to comprehensively meet the requirements of CUAVs with long endurance and multiple hovers. The particular ability of the solar-powered fixed-wing unmanned aerial vehicle (UAV), pure battery-powered CUAV, and the proposed long-endurance solar-powered CUAV with multiple cruises and hovers were comparatively analyzed from an energy standpoint. Second, a suitable conceptual design method and process for small solar-powered CUAV was given, and the robustness of the designed CUAV was using three performance metrics under nominal conditions. The approach was then applied to design a 6.5 kg CUAV, which was initially tested in flight. Finally, the performance and application potential of the designed CUAV was evaluated with operating conditions, mission requirements, energy input, and perpetual flight capability.

具有多倾斜和悬停功能的长航时小型太阳能无人机概念设计

提出了一种采用倾转旋翼进行多悬停任务的长航时小型太阳能可转换无人机(CUAV)的总体方案。首先，提出了太阳能/电池混合能源策略，以全面满足无人机的长续航力和多次悬停需求。从能源的角度比较分析了太阳能固定翼无人机、纯电池驱动的无人驾驶飞机和所提出的多巡航、多悬停长航时太阳能无人驾驶飞机的特殊能力。其次，给出了适用于小型太阳能无人驾驶飞行器的概念设计方法和流程，并利用三个性能指标对所设计的无人驾驶飞行器进行了鲁棒性测试。该方法随后被应用于设计一种6.5公斤的无人驾驶飞行器，并进行了初步的飞行测试。最后，从工作条件、任务要求、能量输入和永久飞行能力等方面对所设计的无人飞行器的性能和应用潜力进行了评估。
