The invention relates to a dwelling unmanned aerial vehicle with empennage components and slidable wings. The dwelling unmanned aerial vehicle is of a fixed wing structure and is mainly used for realizing dwelling flight, and the dwelling unmanned aerial vehicle is provided with wings capable of moving back and forth and a pair of small power propeller components. The wings change the aerodynamiccenter positions of the wings through front-back sliding, and adjustment of the pitching posture is achieved. The propeller assembly is installed at the tail of an airplane and is composed of a motorinstallation base, a small brushless motor and blades. The pair of propeller assemblies rotate clockwise and anticlockwise respectively in the working process, upward and downward pull force is generated respectively, and the unmanned aerial vehicle can generate head lowering moment and head raising moment. At the tail section of the dwelling maneuver, the control surface control efficiency of theunmanned aerial vehicle is very low, pitching attitude control is difficult to realize by virtue of control surface deflection, and the unmanned aerial vehicle provided by the invention provides pitching control moment by utilizing the movable wings and the power propeller assemblies, so that the problem that the pitching attitude of a traditional fixed-wing unmanned aerial vehicle at the tail section of the dwelling maneuver is difficult to control is solved.
本发明涉及一种含尾翼组件且机翼可滑动的栖落无人机,所述无人机为固定翼构型主要用于实现栖落飞行,该无人机配有可前后移动机翼和一对小型动力螺旋桨组件。所述机翼通过前后滑动改变机翼气动中心位置,实现俯仰姿态的调节。所述螺旋桨组件安装在飞机尾部由电机安装座、小型无刷电机和桨叶三部分组成。所述一对螺旋桨组件在工作时分别按照顺、逆时针旋转,分别产生向上和向下的拉力,可使无人机产生低头和抬头力矩。在栖落机动末段,无人机舵面操纵效率很低,依靠舵面偏转很难实现俯仰姿态控制,而本发明无人机利用所述可移动机翼和动力螺旋桨组件提供俯仰控制力矩,解决了传统固定翼无人机在栖落末段俯仰姿态难以控制的问题。
