The vertical unmanned aerial vehicle comprises a fuselage, fixed side wings are arranged on the two sides of the fuselage, telescopic side wings are arranged in the fixed side wings in a sliding mode, and the ends, away from the fuselage, of the telescopic side wings penetrate through the side walls of the fixed side wings and extend outwards. Telescopic driving assemblies are further arranged in the fixed side wings and used for driving the telescopic side wings to slide. Through the telescopic driving assembly, the fixed side wings and the telescopic side wings can adjust the aspect ratio according to the flight mode; when the endurance needs to be improved, the extension length of the telescopic side wings is maximum, the lift-drag ratio is increased, the gliding performance is improved, and the endurance is improved; when the aircraft needs to fly in severe weather or take off in a narrow space, the telescopic side wings are contracted, and the power and wind resistance of the engine are improved; when the unmanned aerial vehicle needs to be stored, the telescopic side wings are contracted to the minimum, and the design size of the hangar is reduced.
本发明公开了一种具有伸缩机翼的垂起无人机,涉及无人机技术领域,包括机身,所述机身两侧均设有固定侧翼,所述固定侧翼内部滑动设置有伸缩侧翼,所述伸缩侧翼远离所述机身一端贯穿所述固定侧翼侧壁并向外伸出,所述固定侧翼内部还设有伸缩驱动组件,所述伸缩驱动组件用于驱动所述伸缩侧翼滑动。本发明通过伸缩驱动组件能够使固定侧翼与伸缩侧翼根据飞行模式调整展弦比;需要提高续航时,使伸缩侧翼伸出长度最大,增加升阻比、提高滑翔性能,增加续航;需要在恶劣天气飞行,或者在狭小空间起飞时,使伸缩侧翼收缩,提高发动机功率以及抗风性能;需要存储无人机时,将伸缩侧翼收缩至最小,减小机库设计体积。
