The invention provides an open type propeller pitch adjusting mechanism, a rotor wing and an aircraft, the open type propeller pitch adjusting mechanism comprises a middle connecting seat, at least one pair of oppositely arranged propeller clamps and a driving assembly, the middle of the middle connecting seat is arranged in a penetrating mode to form a movable space, the propeller clamps are rotatably connected to the middle connecting seat, and the driving assembly is arranged on the middle connecting seat and is used for driving the propeller clamps to rotate. The driving assembly comprises a driving part, a transmission part and a translation part, the driving part, the transmission part and the translation part are sequentially in transmission connection, the middle of the translation part is arranged in the moving space, the two ends of the translation part extend out of the moving space, and the driving part is used for driving the translation part to horizontally move in the moving space in the radial direction parallel to the paddle clamp rotating plane through the transmission part; the two ends of the translation piece are movably connected with the paddle clamps located on the two opposite sides of the middle linkage base in a limiting mode and used for pushing the paddle clamps to rotate in a limiting mode when the translation piece horizontally moves. The aerodynamic lift coefficient of the blades on the rotor wings is changed by adjusting the pitch of the blades, and then the purpose of changing the lift force of the aircraft is achieved.

    本发明提供了一种开放式桨距调节机构、旋翼及飞行器,其中开放式桨距调节机构包括中联座、至少一对相对设置的桨夹、驱动组件,中联座的中部贯穿设置以形成一活动空间,桨夹转动连接于中联座上,驱动组件设置于中联座上,驱动组件包括驱动件、传动件、平移件,驱动件、传动件以及平移件依次传动连接,平移件的中部设于活动空间内且其两端延伸至活动空间外,驱动件用于通过传动件驱使平移件在活动空间内沿平行于桨夹旋转平面的径向水平移动,平移件的两端分别与位于中联座相对两侧的桨夹限位活动连接,用于在其水平移动时限位推动桨夹旋转。本发明通过调节桨叶的桨距来改变旋翼上的桨叶的气动升力系数,进而达到改变飞行器升力的目的。
