The invention discloses a cross-medium multi-rotor unmanned aerial vehicle, and belongs to the field of unmanned aerial vehicles. The cross-medium multi-rotor unmanned aerial vehicle comprises an upper fuselage and a lower fuselage which are fixedly connected in a stacked manner, wherein the lower fuselage is ship-shaped so as to sail in the water, and a tail vane is mounted at the tail of the lower fuselage; at least two pairs of arms are symmetrically arranged on the left side and the right side of the lower fuselage relative to the central axis of the lower fuselage, wherein tilting bases are rotatably connected to the tips of the arms, ducted propellers are fixedly mounted on the tilting bases, a tilting steering engine is connected between the arms and the tilting bases to drive the tilting bases to rotate, the rotating axes of the tilting bases are perpendicular to the central axis of the lower fuselage, and the ducted propellers are perpendicular to the rotating axes of the tilting bases. When the unmanned aerial vehicle lands on the water surface from the air, the thrust direction of the ducted propellers is changed through tilting of the tilting bases, so that movement of the unmanned aerial vehicle on the water surface is achieved; meanwhile, a ducted propeller system has the advantages of being higher in aerodynamic efficiency, low in aerodynamic noise, high in safety and the like.

    本发明公开了一种跨介质多旋翼无人机,属于无人机领域,包括层叠状固定连接的上机身和下机身,下机身呈船型以便于在水中航行,且下机身的尾部安装有尾舵;下机身的左、右两侧关于下机身的中轴线对称地布置有至少两对机臂,机臂的臂梢处均可转动连接有倾转底座,倾转底座上固定安装有涵道螺旋桨;其中,机臂与倾转底座之间连接有倾转舵机以驱动倾转底座转动,且倾转底座的转动轴线垂直于下机身的中轴线,涵道螺旋桨垂直于倾转底座的转动轴线。本发明无人机从空中降落到水面上时,通过倾转底座的倾转改变涵道螺旋桨的推力方向,实现无人机在水面上的运动,且涵道螺旋桨系统具有更高的气动效率以及气动噪声低、安全性高等优点。
