Abstract

The application discloses a marine propulsion device based on a bypass passive thrust vectoring nozzle and a propulsion method thereof. The propulsion device includes a pod front power device. A liquid flow outlet of the pod front power device is communicated with a bypass passive thrust vectoring nozzle. The bypass passive thrust vectoring nozzle is equipped with a pod connecting end on the outerwall. The water flows through power components of the hull and then flows through a transition section into the bypass passive thrust vectoring nozzle, when the bypass passive thrust vectoring nozzleworks, the water will be deflected to further subject the hull to a left or right control force, then a corresponding control torque is produced, and the traveling direction of the hull is changed. In the invention, the performance characteristics that the bypass passive thrust vectoring nozzle can take water as a working medium are used, the bypass passive thrust vectoring nozzle is mounted at the rear portion of the transition section, the pod has no rotating parts and can make the traveling direction of the hull change, and the maneuverability of the ship is improved.

Description

technical field [0001] The invention designs a marine propulsion pod device using a bypass type passive thrust vectoring nozzle, which is mainly used to improve the maneuverability of the ship, simplify the structure and improve the reliability of the ship's power system. Background technique [0002] Today, the pod propeller used in the ship's power plant is a ship propulsion device that integrates propulsion and steering devices. Podded thrusters place the propulsion motor outside the cabin, directly connected to the propeller. Generally, it is mainly composed of a built-in drive motor module, a propeller module, a horizontal rotation mechanism and a cooling device. However, due to the complexity of the horizontal rotation mechanism, the pod propeller has disadvantages such as poor maintainability, high failure rate, and low economy. Therefore, the present invention designs a novel marine pod that replaces the common propeller pod, and the pod can change the driving dire...
