Abstract (en)
[origin: EP3508415A1] A diffuser-type endplate propeller (100) driving a hull (20) and including a propeller hub (110) a plurality of blades (120) is provided. The propeller hub (110) has an axis (L) of rotation and is connected to a transmission shaft (22) of the hull (20). The blade (120) has a blade-body (122) and an endplate (124). The blade-body (122) is connected to the propeller hub (110) and extends outward from the propeller hub (110) to the corresponding endplate (124), the endplate (124) bends from the corresponding blade-body (122) to extend towards a stern (24) of the hull (20), and the endplate (124) has a leading edge (124a) and a trailing edge (124b). A cylindrical surface (S1) is imaginarily formed by the leading edges (124a) while the diffuser-type endplate propeller (100) is rotated about the axis (L). Each of the endplates (124) has a first tangent plane (C1) at the leading edge (124a) thereof, the cylindrical surface (S1) has a second tangent plane (C2) at the leading edge (124a). An included angle (α) is measured from the second tangent plane (C2) to the first tangent plane (C1).
