Corrosion-Resistant Marine High-Efficiency Thruster Propeller for Commercial Boat

Product Description

We can manufactor better design propeller for your boat to get more speed and save at least 3% to 8% fuel and oil.

Specification

Applications

Commercial shipping: Used in cargo ships, container ships, oil tankers, and bulk carriers to provide propulsion for long-distance transportation of goods.

Passenger transportation: Applied to cruise ships, ferries, and passenger liners to drive the vessels and ensure the safe and efficient travel of passengers.

Recreational boating:  Installed on yachts, speedboats, and fishing boats to power leisure and sports activities on the water.

Key Configurations
Blade	The leaf-like part of the propeller, which is the core component for generating thrust. Usually, there are 3-6 blades, distributed symmetrically.
Hub	The central part connecting all the blades, with a shaft hole inside, used to connect with the ship's stern shaft and transmit power.
Blade root	The part where the blade connects to the hub, which needs to bear large torque and stress, and has high structural strength.
Blad tip	The outermost end of the blade, with the highest linear speed, which has a certain impact on the efficiency and cavitation performance of the propeller.
Pressure face	The working surface of the blade, usually the pressure side, where the water flow is squeezed to generate thrust.
Suction face	The non-working surface of the blade, opposite to the pressure face, where the water flow has lower pressure when passing through.
Leading edge	The edge of the blade facing the water flow, with a thin arc shape, which can reduce water flow impact.
Trailing edge	The edge of the blade opposite to the leading edge, on the side away from the incoming water flow.
Hub cap	A cover installed at the end of the hub, which can reduce water flow resistance and protect the hub connection part.
