Mechanically driven bossless ship propulsion device with high efficiency

摘要

The invention relates to a mechanically driven, hubless, high-efficiency ship propulsor comprising at least one rotor having blades (10) in a ring, wherein the rotor fitted with a gear rim is joined to the engine of a ship via a shaft (1) having pinions (2) for transferring a torque, and wherein the rotor is arranged in an orifice (8) and wherein rotating blades (10) of the rotor are constructed to be individually adjustable in angle and upon each rotation allow a continuous adaptation of the angular position thereof to the local flow conditions, in particular to the inflow conditions in the orifice (8).
