The invention relates to a winged knife structure and a tailstock type vertical take-off and landing unmanned aerial vehicle, the winged knife structure comprises a winged knife, the winged knife is of an arc-shaped plate-shaped structure, a notch extending from the middle of one end to the position close to the other end is formed in the winged knife, and a connecting mechanism used for detachably connecting the winged knife to the unmanned aerial vehicle is installed on the winged knife. The tail seat type unmanned aerial vehicle has the beneficial effects that the structure is simple, the design is reasonable, the occupied size is small, the design of the wing knife considers that the take-off and landing process of the tail seat type unmanned aerial vehicle is in a multi-rotor-like state, the control torque in the pitching and yawing directions is provided for the control surface, and the control torque of the control surface is positively correlated with the flow speed of the propeller slip flow flowing through the control surface; therefore, a winged knife needs to be provided for rectification, airflow flowing through the control surface is increased, and the steering effect is improved. In addition, the winged knife is detachably installed on the unmanned aerial vehicle through the connecting mechanism, disassembly and assembly are convenient, follow-up maintenance is facilitated, and time and labor are saved.
本发明涉及一种翼刀结构及尾座式垂直起降无人机,该翼刀结构包括翼刀,翼刀呈弧形板状结构,且其上具有从一端中部延伸至靠近另一端位置的缺口,并安装有用于将其可拆卸的连接在无人机上的连接机构。本发明的有益效果是结构简单,设计合理,占用体积小,翼刀的设计是考虑尾座式无人机其起降过程为类多旋翼状态,其俯仰和偏航方向的控制力矩为舵面提供,而舵面的控制力矩大小和其上流过的螺旋桨滑流流速大小成正相关,因此需要提供翼刀整流,增大流过舵面的气流,从而增加舵效;另外,翼刀通过连接机构可拆卸的安装在无人机上,拆装方便,便于后续维修,省时省力。
