差速型船用平旋推进装置的桨叶
摘要：
本实用新型公开了差速型船用平旋推进装置的桨叶，桨叶的横截面呈带有两尖头的指针形，每一尖头的两侧边呈弧形，两尖头分别指向异侧。本实用新型差速型船用平旋推进装置的桨叶呈全对称翼型结构，其旋转时受力面更大，提高了船舶的推进效率。
摘要（英）：

The utility model discloses a paddle of a horizontal rotary propelling device for a differential speed type ship, the cross section of the paddle is in an indicator shape with two tips, two side edges of each tip are arc, and the two tips point to different sides respectively. The paddle of the horizontal rotary propelling device for the differential speed type ship has a fully-systematical wing-shaped structure, and the stress area is larger in rotation, therefore, the propelling efficiency of the ship is improved.
