Description

一种机翼角度可调的无人机 技术领域
本发明涉及无人机领域，特别是涉及一种机翼角度可调的无人机。
背景技术
近年来，随着无人飞行器技术的发展和成本的降低，无人机已在军事、安保、交通、勘探、测绘、气象、农业等各个领域广泛应用。在一些民用领域上，无人机一般用来对农作物进行农药喷洒，然而现有的无人机上的喷洒装置一般都是固定位的，无法改变喷洒的范围，在对一些较大的田地喷洒时，需要来回几趟才能完成作业，而在对一些较小的田地喷洒时，则很容易将农药喷洒到田地外的道路，造成了农药的浪费，而如果换成一个可转动的喷洒装置的话，则需要一个更大的喷洒装置，进而加重无人机的负担，如果机翼不够大的话甚至要安装到机翼外，对飞机的飞行造成多余的风阻，加大飞机的能源消耗。
因此，有必要设计一种机翼角度可调的无人机以及调节方式解决上述问题。

进一步地，所述第二旋转翼为中空结构，所述第二旋转翼内收纳一辅翼，所述第二旋转翼在在后端开设一开口，当展开所述辅翼时，所述辅翼经所述开口弹出。
无人机在不使用所述辅翼的时候可以收纳所述辅翼，减小无人机的占用空间，且当无人机遇到动力事故，也可以伸出所述辅翼增大空气阻力，减缓无人机迫降的速度，降低无人机的损伤。
进一步地，所述第一旋转翼整体呈流线型，所述喷洒枪的枪口朝后，所述喷洒枪的下表面为弧面，并与所述第一旋转翼的下表面共面。
