Introduction of propeller

The index is the most basic propeller pitch, pitch definition assumes that there is no slippage under the condition that the distance of propeller rotates a circle along the pitch; the essence of the pitch and screw is the same, is the time to the wood screw, screw a screw ring, forward distance. Pitch propeller, need thrust, rotates one circle along the distance (twist effortlessly, but soon all screwed in); small pitch, need thrust is small, but each rotation of a circle along the distance is short (screwed up easily, but spend a lot of time).

Usually for overloaded ship, we hope to provide some outboard engine torque, propeller pitch bigger, higher propulsive efficiency; for a light boat, on torque requirements are not so high, propeller pitch smaller, higher speed, higher propulsive efficiency.
