The invention provides a solar unmanned aerial vehicle with tilting wings. The solar unmanned aerial vehicle comprises the wings, solar cells, storage batteries, motors, propellers, power nacelles, tilting mechanisms, undercarriages, a flight control system, an electrical system and a measurement and control system. The solar unmanned aerial vehicle adopts a flying wing layout, and wings are of a pneumatic structure with a high aspect ratio and a small sweepback angle; flexible thin film solar cells are laid on the upper surfaces of the wings; a storage battery capable of being charged and discharged circularly is mounted in the wing; a variable pitch propeller driven by a motor is mounted on each of two wing tips of the wings; the tilting mechanism mounted in the power nacelle can drive the outer wing sections on the two sides of the wing to tilt by more than 90 degrees; a retractable undercarriage is arranged at the front part of the position of the symmetry plane of the wing; airborne avionics equipment of flight control, electrical and measurement and control systems and the like is installed in the wings. The unmanned aerial vehicle has the advantages of a fixed-wing solar aircraft and a rotorcraft, and not only can realize vertical take-off and landing, hovering and side flight, but also can realize long-distance flight during long endurance.

    本发明提出了一种倾转机翼太阳能无人机,包括机翼、太阳电池、蓄电池、电动机、螺旋桨、动力短舱、倾转机构、起落架、飞控系统、电气系统和测控系统。太阳能无人机采用飞翼布局,机翼为大展弦比小后掠角气动构型;机翼上表面铺装有柔性薄膜太阳电池;机翼内部安装有可循环充放电蓄电池;机翼两侧翼梢各安装一套电动机驱动的变距螺旋桨;安装于动力短舱内的倾转机构可驱动机翼两侧外翼段实现90度以上的倾转;机翼对称面位置前部布置一个可收放式起落架;飞控、电气和测控等系统的机载航电设备安装于机翼内部。该无人机兼具固定翼太阳能飞机和旋翼机的优点,既能实现垂直起降、悬停、侧飞,又能实现长航时远距离飞行。
