the following example is for you reference.


1.Brief Introduction:

the propeller blade of the main controllable pitch Propeller is not fixed to the hub, the blades revolve around the axis Perpendicular to the oar axis, revolving the blades by turning the control Construction in the hub, which can vary pitch angle to change the thrust and Direction. this kind of propeller also can make full use of host power includes the situation while the ship is running or towing.

2.Techincal parameters:

the hub divides into 3 types:

Hubs Type
Type	Characteristic	Remark
Type KS	Hub as a whole Grain	Common type
Type KL	Hub as a whole Grain and it contains the oil cylinder	Common type
Type SE	Hub as two Half-grains	Use fewer

Type and Specification

102	1020	KL/SE	3710	6710
111	1110	KL/SE	4040	8800
121	1210	KL/SE	4800	11400

3.Performance features:

Faired hub. Low fuel Consumption. without cavitation. Especially suitable for high-speed ships. Sturdy Construction. Simple maintenance. Reducing the diameter of the hub. Improving the propulsive efficiency
