Embodiment
Embodiment one
In order to make the purpose of this utility model, technical solution and advantage clearer, below in conjunction with the accompanying drawings and it is embodied
The utility model is described in detail in example.
Refering to Fig. 1 the utility model a kind of mixing of ship to turning propulsion system, including be arranged in engine space 3 rudder 1,
Rudder horn 2, host 4, propeller shaft 5, front propeller 6, aft propeller 7 and PODDED PROPULSOR 8, the transmission of host 4 connect
The propeller shaft 5 is connect, the fixedly sleeved front portion is spiral in the circumferential direction of the one end of the propeller shaft 5 away from the host 4
Paddle 6, is equipped with the aft propeller 7 and the PODDED PROPULSOR 8, the gondola is promoted along the axial direction of the propeller shaft 5
Device 8 is drivingly connected the aft propeller 7, and the PODDED PROPULSOR 8 is fixed on the rudder horn 2, and the rudder horn 2 is affixed
The rudder 1.
Front propeller 6 and aft propeller 7 are mutually independent two propulsion systems, and when operation is made by reversely rotating
The method of paddle recycling bow oar wake flow rotating energy loss improves the propulsive efficiency of whole propulsion system afterwards.
Front propeller 6 is by 4 direct-driven airscrew of host, and aft propeller 7 is gondola propulsion mode, PODDED PROPULSOR
8 are integrated on rudder horn 2, therefore it cannot 360 degree of full circle swingings.Which is fairly simple mainly in conjunction with bulk freighter operating mode,
Well adapting to property and advantage in cost, installation and maintenance, operation ease and control.
PODDED PROPULSOR 8 uses permanent magnet synchronous motor, and aft propeller 7 is directly driven by variable frequency drives.Gondola pushes away
