With the requirements of energy conservation and emission reduction, the shipping and marine tourism industries are more and more greatly influenced, the green and low carbon become the key points of current shipping industry attention, and the consumption of energy is larger due to the characteristics of more passengers carried by ships, complex functions, strong maneuverability of the ships and the like, particularly large passenger ships. Among the energy consumption of various devices of the ship, the energy consumption of a propulsion system is more, so that a series of power propulsion systems of new energy sources are applied and researched on a passenger ship.

In the prior art, wind energy is a relatively mature and conveniently-obtained green energy, but the design of a wind power auxiliary system of a ship is limited by factors such as weight, windward area and the like because the ship has the characteristics of plump building, sensitive stability and the like. Wind sails are often used in the prior art to capture wind energy, but their use in large vessels, particularly large passenger ships, has a number of limitations. Firstly, wind energy cannot be fully utilized, the sail of the ship is firstly arranged at a high position of the top of the ship to fully utilize a wind field, so that the sail device is required to be light in weight and high in structural strength, and the flexible sail used by the traditional sailing ship cannot meet the condition; secondly, after the sail is unfolded, a huge crosswind area is formed, and on the premise of meeting stability balance, if the sail is unfolded all the time, the gravity center height of the ship is greatly limited, so that the area of the sail needs to be adjusted automatically under the severe wind speed condition to avoid the risk of overturning caused by the formation of an overlarge heeling moment; finally, when the sail is applied to a passenger ship, the sail occupies a larger area of the weather deck at the top of the passenger ship, and further reduces the operation area of a public area at the top of the passenger ship, so that the application and arrangement of the sail system on the top deck are required to reduce the occupation of space as much as possible.

Therefore, it is desirable to design a lightweight, adjustable and easily deployable wind-assisted propulsion system to increase the propulsion efficiency of a vessel, particularly a passenger ship, and to reduce the energy consumption of the vessel.
