The invention discloses a drag reducer of an aircraft, which comprises a plurality of cylinders which can slide, extend and retract and are sleeved with one another, and the number of the cylinders is multiple, the interiors of the cylinders are hollow, and the sizes of the cylinders are sequentially increased; and the inner diameter surface and the outer diameter surface of the cylinder body are matched in a manner of extending out and not retracting back through an inverted buckling structure. Due to the fact that the inner diameter faces and the outer diameter faces of the cylinders can be matched in an extensible and non-retractable mode through the back-off structures, the cylinders are in an extensible state all the time through the back-off structures after sliding and extending, force does not need to be provided for maintaining, energy on the aircraft can be more used for flying, and therefore the flying range of the aircraft is increased, and the flying efficiency is improved. The problem that the telescopic rod needs to continuously consume energy during flight drag reduction is solved.

    本发明公开了一种飞行器的减阻器,包括:彼此可相互滑动伸缩套装的筒体,筒体数量为多个内部为中空尺寸依次增大;所述筒体彼此内外径面之间经倒扣结构实现可伸出而不可缩回的配合。由于筒体彼此内外径面之间经倒扣结构实现可伸出而不可缩回的配合,在多个筒体彼此滑动伸出后通过倒扣结构一直处于伸出的状态而不需要提供力来维持,飞行器上的能量可更多用于飞行,以此提高飞行器的飞行航程,解决了可伸缩的伸缩杆在飞行减阻时需要持续消耗能量的问题。
