Title:
PROPELLER
Document Type and Number:
WIPO Patent Application WO/1987/003263
Kind Code:
A1
Abstract:
A propeller for a high-speed sea-vessel comprises a hub (1) mounted on an inclined propeller shaft and blades (2) fixed to it, each of the blades being diverted, along its whole length, in the direction opposite to that of rotation of the propeller shaft. The angle (X) of divergence of the leading edge in the root cross-section (3), formed by the tangent (4) in the point of the leading edge in that cross-section and by the line (5) drawn to the same point perpendicularly to the geometrical axis of the hub (1) equals 30o-45o, whereas the angles of divergence of the leading edge of each blade (2) in subsequent cross-sections increase continuously .
