Custom High Speed Propeller Thrust Blade Axial Screw Shaft Ship Propeller

The controllable pitch propeller (CPP) can be effective in the full range of speed and load conditions, because its pitch will change to absorb the maximum power that the engine can produce. When the ship is fully loaded, it obviously needs more propulsion than when it is empty. By changing the propeller blade to the optimum pitch, higher efficiency can be achieved, thus saving fuel. Ships equipped with VPP can accelerate faster and decelerate more effectively from the static state, making parking faster and safer. CPP can also improve the ship's mobility by guiding stronger water flow to the rudder. Its characteristics are excellent operability and economy. Minimize noise and vibration levels. Advantages in ship control. Propellers can be driven by electric motors, diesel engines and hydraulic motors.

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.
