Abstract

The invention relates to a propeller arrangement for vessels comprising a shaft 4 provided with propeller and a propeller ring placed around the propeller. In order that the propeller may have a hydrofoil section 7 with good lift-drag ratio, which increases the thrust, the speed and power in a fixed or variable propeller functioning on the inside of the propeller ring, the propeller ring part has been provided with continuously curved inside 8 and outside 9 for achieving maximum load bearing capacity and minimum resistance. For larger propellers used in vessels and in order to reduce the manufacturing costs, the propeller ring is manufactured from plates made of steel, stainless steel or other suitable material in the form of a number of straight hydrofoil segments 3, which form a polygon reminiscent of a circular ring. <IMAGE>
