Summary of the advantages of controllable propeller
The advantages of controllable propeller are summarized as follows:
The controllable propeller can make full use of the full power of the main engine under any conditions. Without changing the speed of the main engine, the pitch can be adjusted to adapt to the various sailing conditions of the ship, which can shorten the time required for the ship to move from full speed to retreat. And the distance, the maneuverability of the ship has been significantly improved. When the ship is advancing, decelerating, retreating, etc., there is no need to change the speed and steering of the main engine at all, so the speed of the main engine is significantly reduced, reducing the degree of wear of machine parts and extending the service life of the main engine. For diesel engine or turbine ship, the use of controllable propeller can save the whole set of reversing device of the main engine. If the engine speed n and the pitch ratio P/D are changed at the same time and matched appropriately, the fuel consumption of the ship in the first fixed time can be minimized.
