Large Boat High Speed Propeller Thrust Blade Axial Screw Shaft Ship Propeller

The progress of propeller blades, relying only on the intuitive reasoning of experts, can no longer meet the needs of the development of ship technology. It needs scientists to make a complete explanation of its hydrodynamic characteristics, which will promote the development of propeller theory.

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.
