The invention provides an air-breathing electric propulsion unmanned aerial vehicle utilizing solar energy, which comprises a vehicle body, an annular truss type photoelectric conversion device is carried on the vehicle body, the photoelectric conversion device comprises an annular truss unfolding mechanism and a foldable film type photoelectric conversion array, and the film type photoelectric conversion array is supported and connected by the annular truss unfolding mechanism. Unfolding or folding of the film type photoelectric conversion array is realized through the annular truss unfolding mechanism; a thrust device is arranged on the fuselage, and an air suction type electric propulsion device is adopted as the thrust device. The annular truss type photoelectric conversion device is used, the design of the large unfolding and folding ratio of the solar thin film can be achieved, meanwhile, the structure is simple, and the structural mass can be effectively reduced. The air-breathing electric propulsion is used as a power device, no extra propellant needs to be carried, gas can be taken from the surrounding rarefied atmosphere to serve as the propellant, the gas can generate corresponding thrust after ionization acceleration, and the unmanned aerial vehicle can work on orbit for a long time.

    本发明提出一种利用太阳能的吸气式电推进无人机,包括机身,机身上搭载有环形桁架式的光电装换装置,光电装换装置包括环形桁架展开机构以及可折叠的薄膜式光电转换阵列,薄膜式光电转换阵列由环形桁架展开机构支撑连接,通过环形桁架展开机构实现薄膜式光电转换阵列的展开或折叠;机身上设有推力装置,推力装置采用吸气式电推进装置。本发明使用环形桁架式的光电装换装置,可实现太阳能薄膜的大展收比设计,同时结构简单,可有效减轻结构质量。本发明使用吸气式电推进为动力装置,无需额外携带推进剂,可从周围稀薄大气中摄取气体作为推进剂,气体经过电离加速后可产生相应推力,无人机可长时间在轨工作。
