The invention relates to a fixed-wing unmanned aerial vehicle capable of enhancing pitching control performance of a dwelling tail section. On the basis of a traditional fixed-wing unmanned aerial vehicle configuration, a pair of small power propeller assemblies is additionally arranged at the empennage part; the assembly is composed of a motor mounting base, a small brushless motor and blades. The two power propeller assemblies rotate in the clockwise direction and the anticlockwise direction respectively in the working process, so that upward pull force and downward pull force are generatedat the empennage part respectively, and the pair of pull force enables the unmanned aerial vehicle to generate head lowering moment and head raising moment relative to the gravity center of the unmanned aerial vehicle. At the tail section of the dwelling machine; due to the fact that the flight speed is low, the control rudder effect of an elevator of a traditional fixed-wing unmanned aerial vehicle is very low, the pitching posture is difficult to control accurately, the fixed-wing unmanned aerial vehicle can provide high pitching control torque through the power propeller assembly, and thenthe problem that the pitching posture of the traditional fixed-wing unmanned aerial vehicle at the perching tail section is difficult to control accurately is solved.
本发明涉及一种增强栖落末段俯仰控制性能的固定翼无人机,在传统固定翼无人机构型的基础上在尾翼部位增加一对小型的动力螺旋桨组件,该组件由电机安装座、小型无刷电机和桨叶三部分组成,所述两个动力螺旋桨组件在工作时分别按照顺时针和逆时针方向旋转,从而在尾翼部位分别产生向上和向下的拉力,这一对拉力相对于无人机重心分别使无人机产生低头力矩和抬头力矩。在栖落机动末段,由于飞行速度较低,传统固定翼无人机升降舵的操纵舵效很低,使得俯仰姿态难以精准控制,而本固定翼无人机利用所述动力螺旋桨组件可提供较强俯仰控制力矩,进而解决传统固定翼无人机在栖落末段俯仰姿态难以精准控制的问题。
