The invention relates to the technical field of empennages of unmanned aerial vehicles, in particular to an unmanned aerial vehicle empennage which comprises a horizontal empennage, a vertical empennage and a sliding rod, a part of the sliding rod is arranged in an unmanned aerial vehicle body, and the sliding rod in the unmanned aerial vehicle body is slidably sleeved with a sliding cylinder; a horizontal oil cylinder and a vertical oil cylinder are arranged in the unmanned aerial vehicle body. One end of a piston rod of the horizontal oil cylinder is hinged to the end of the sliding rod. The vertical oil cylinder is hinged to the middle of the sliding cylinder. The horizontal oil cylinder and the vertical oil cylinder are controlled by a control system; a piston rod of the vertical oil cylinder is provided with a first displacement sensor and a first force sensor which are connected with a first controller; a piston rod of the horizontal oil cylinder is provided with a second displacement sensor and a second force sensor which are connected with the second controller; the unmanned aerial vehicle is further provided with a flight state monitoring module. The position of the empennage of the unmanned aerial vehicle relative to the unmanned aerial vehicle body is accurately and finely adjusted in real time through axial stretching and vertical swinging, and it is guaranteed that the unmanned aerial vehicle adapts to a new flight environment and a new flight attitude.
本发明涉及无人机的尾翼技术领域,具体提供了一种无人机尾翼,包括水平尾翼、垂直尾翼以及滑动杆,滑动杆的一部分设置在无人机主体内,无人机主体内的滑动杆的上滑动套设有滑筒;无人机主体内设置有水平油缸和竖直油缸,水平油缸的活塞杆一端与滑动杆端部铰接;竖直油缸与滑筒中部铰接;水平油缸和竖直油缸均由控制系统控制;竖直油缸的活塞杆上设置有与第一控制器连接的第一位移传感器和第一力传感器;水平油缸的活塞杆上设置有与第二控制器连接的第二位移传感器和第二力传感器;无人机还具有飞行状态监测模块。通过轴向伸缩和竖直方向的摆动将无人机尾翼相对于无人机主体的位置进行实时精确微调,保证无人机适应新的飞行环境和飞行姿态。
