[0044] The technical solutions of the present invention will be further specifically described below through examples and in conjunction with the accompanying drawings.
[0045] See Figure 1,
[0046] The type selection and design method of the main propulsion adjustable pitch propeller device for ships of the present invention comprises the following steps in turn:
[0047] A. The size should be determined. According to the parameters of the hull, main engine and gearbox, select the diameter of the propeller hub d H , and according to the propeller series map, determine the blade diameter D, disk surface ratio EAR, pitch ratio P / D, efficiency η, blade number z of the controllable pitch propeller;
[0048] B. Determination of inertial elements, according to the empirical formula to determine the mass and moment of inertia of the controllable pitch propeller blade:
[0049] Blade mass G b = k G ...
