The invention discloses a retractable angle-adjustable helicopter stub wing. A fuselage, an empennage and a stub wing are included, an undercarriage is mounted under the fuselage; a main rotor is installed at the top of the fuselage, the empennage is arranged at the tail end of the fuselage, the stub wing is arranged on the outer side of the middle of the fuselage, a storage cavity located in thefuselage is formed in the outer side of the stub wing, a hinge is installed at the tail end of the stub wing, a driver is installed in the storage cavity, and a center control box is arranged on the outer side of the driver. According to retractable angle-adjustable helicopter stub wing, the defect that the stub wing of a retractable helicopter cannot be unfolded in high-speed movement is overcome; the defect that the included angle between a stub wing and a fuselage of a retractable helicopter is fixed and cannot be adjusted is overcome, the stub wing can be adjusted when the helicopter fliesforwards at a high speed, flies in a circling maneuvering mode, hovers, takes off and lands vertically, flies at a low speed and slides down in an autoroatation mode, and power can be used to the maximum extent.
本发明公开了一种可收放可调角度式直升机短翼,包括机身、尾翼和短翼,所述机身的下方安装有起落架,且机身的顶部安装有主旋翼,所述机身的末端设置有尾翼,且机身的中部外侧设置有短翼,所述短翼的外侧设置有位于机身的内部的收纳腔,且短翼的末端安装有铰链,所述收纳腔的内部安装有驱动器,且驱动器的外侧设置有中控盒。该可收放可调角度式直升机短翼,解决了伸缩式直升机短翼不能在高速运动中展开的弊端,解决了伸缩式直升机短翼与机身夹角固定不可调节弊端,在直升机大速度前飞时,在盘旋机动飞行时,在悬停、垂直起降及低速飞行状态下,在自转下滑时,均能够针对短翼进行调节,能够最大程度的进行动力的使用。
