摘要： An impeller for a turbo pump in a water jet propulsion machinery used as propulsion means for ships having a volute casing or a diffuser type casing. The configuration of meridian section of an impeller shroud at the side of a boss is made as a concave arc-like surface of revolution, said boss shroud at the side of the blade inlet being formed in a cylindrical form substantially parallel to a rotary shaft, and each of the blades of the impeller is so shaped that the edge of the blade inlet projects greatly toward the impeller eye with said edge being smoothly connected to the surface of said boss shroud at the blade inlet boss shroud side and the edge of the blade inlet at the side of the casing extends substantially perpendicalarly to the axis of rotation. The edges of the blade inlet at either of the boss and casing sides are connected by a smooth arc-like curve projecting convexly upstream to thereby form a continuous edge of the blade inlet, and the inlet angle of said edge of the blade inlet are uniform through the entire length and set to an angle nearer to 0 as small as possible, and the configuration of the blade at said blade inlet is connected by a smoothly curved surface to the configuration at the end of the blade outlet shaped as centrifugal or mixed flow type extending parallel or inclined to the rotary shaft.

摘要： In a turbo pump according to the present invention, blades 3e and a shroud 3f are continuously formed with a boss 3c of a turbine wheel 3, a meridian plane configuration of the shroud 3f is formed as an concave arcing rotatable surface. A boss shroud 3f1 is formed substantially parallel to the axis of rotation O. A portion 3e2 of a blade outlet edge 3e1 is smoothly continuous to the boss shroud 3f1 and largely projects downstream. A portion 3e3 of the blade outlet edge 3e1 is formed substantially perpendicular to the axis of rotation O. The blade outlet edge 3e1 is formed with a smooth arc-like curve projecting convexly downstream between the portion 3e3 and the portion 3e2. An angle of the blade outlet edge 3e1 is set to an angle of substantially 0 DEG at the portion 3e2 of the blade outlet edge 3e1 and to substantially the conventional degree of angle at the portion 3e3 of the blade outlet edge 3e1. Further, the blade inlet 3a and the blade outlet 3b are connected there between by a curve.
