Iacs Approved Marine Copper Propeller for Boat/ Ship
Product description
The change process of propeller blade tension with speed is as follows: as the engine output power increases, the propeller speed (tangential speed) rapidly increases to a certain value, and the propeller tension increases. In the process of ship technology development, the design and research of propeller blades has done more than any other professional field, from empirical methods to digital design, and then to the design of optimization of propeller blades by using computer technology. The blade angle of the propeller should gradually increase from the tip to the root according to a certain rule.
The propeller blade of a ship refers to the blade that can rotate in the water, which is a part of the device that converts the rotating power of the engine into the propulsion force. There can be two or more blades connected with the hub. The rear side of the blades is a helical surface or similar to the helical surface.
