The invention relates to a tilting ducted electric unmanned aerial vehicle, a vehicle head is connected with a vehicle body, wings are arranged at the front end of the vehicle body in a bilateral symmetry mode, horizontal empennages are arranged at the rear end of the vehicle body in a bilateral symmetry mode, a rotating assembly is arranged at the wingtip of each wing, and each rotating assembly comprises a damping speed limiting module and an inclination angle limiting stopper; the damping speed limiting modules and the inclination angle limiting stoppers are respectively arranged on wing transmission shafts, the wing transmission shafts and a duct group connecting rod are connected with a combined duct, the combined duct comprises a large duct and a small duct, a large brushless motor is arranged in the large duct, and a small brushless motor is arranged in the small duct; an elevator is arranged at each horizontal empennage, the tail duct is connected with a direct-drive steering engine arranged in the tail end of the fuselage through a tail transmission shaft, and a tail brushless motor is arranged in the tail duct; active tilting is changed into passive tilting by changing a tilting mode, so that the design structure is simplified; by adopting the duct with good safety, the slip flow, the impact noise and the induced resistance of the propeller are effectively reduced, so that the aerodynamic efficiency is improved.

    一种倾转涵道电动无人机,其中,机头与机身连接,机身前端左右对称设置有机翼,机身后端左右对称设置有水平尾翼,并在每个所述机翼的翼尖处设置有转动组件,转动组件包括阻尼限速模块与所述倾角限位器,阻尼限速模块与倾角限位器分别设置在机翼传动轴上,机翼传动轴与涵道组连杆连接组合式涵道,组合式涵道包括大涵道与小涵道,大涵道内设置有大无刷电机,小涵道内设置有小无刷电机;水平尾翼处设置有升降舵,尾涵道通过尾传动轴与设置在机身尾端内部的直驱舵机连接,且在尾涵道内设置有尾无刷电机;通过变更倾转方式,使主动倾转变为被动倾转,从而简化设计结构;采用安全性好的涵道有效减少螺旋桨滑流、冲击噪声与诱导阻力,进而提高气动效率。
