The invention provides a water take-off and landing unmanned aerial vehicle with a vertical tail and a vertical take-off and landing function and a flight control method of the water take-off and landing unmanned aerial vehicle. The unmanned aerial vehicle is composed of a vehicle body trunk, a variant undercarriage and foldable inflatable buoys. The variant undercarriages are symmetrically arranged on the upper side and the lower side of the fuselage and composed of a supporting rod, a tail supporting rod and an upper section and a lower section which are connected through a self-locking mechanism, a horizontal empennage is arranged at the tail of the tail supporting rod, the horizontal empennage is of a scallop type expandable hollow structure, a foldable inflatable buoy is arranged in the horizontal empennage, and the inflatable buoy is connected with an air pump arranged in the fuselage. The variant landing gear and the foldable inflatable buoy can be inflated and deflated through the air pump, during inflation, under the action of air pressure, the horizontal empennage is opened towards the two sides, the inflatable buoy is exposed to make contact with the water surface to provide buoyancy, and after deflation, the horizontal empennage is closed to serve as a control surface to provide control torque. The operation requirements of three modes of vertical take-off and landing/cruising/water take-off and landing of the unmanned aerial vehicle can be effectively met, and the application range of the unmanned aerial vehicle is widened.
本发明提供了一种可水上起降机尾坐立式垂直起降无人机及其飞行控制方法,无人机由机体主干、变体起落架及可折叠充气浮筒组成。变体起落架对称的设置在机身上下两侧,由通过自锁机构连接的支撑杆和尾撑杆上下两段组成,尾撑杆尾部设置有水平尾翼,水平尾翼为扇贝式可张开中空结构,内置可折叠充气浮筒,充气浮筒与机身内置的气泵连接,可通过气泵进行充气与放气,充气时,受气压作用,水平尾翼向两侧张开,充气浮筒露出与水面接触提供浮力,放气后,水平尾翼闭合作为操纵舵面提供操纵力矩,本发明通过变体起落架与可折叠充气浮筒结构功能一体化的设计,可有效的满足无人机垂直起降/巡航/水上起降三种模式的作业需求,增加了无人机的适用范围。
