Description

Technical Field

[0001] This utility model relates to the field of ship propulsion technology, and in particular to a composite propulsion system suitable for new energy ships, specifically a composite ship in which a straight-wing propeller and a hydrofoil work together. Background Technology

[0002] Traditional ship propulsion systems and hull design present a challenge in synergistically optimizing efficiency and maneuverability. Traditional ships suffer from high hull drag, resulting in low cruising speeds and low energy efficiency. Hydrofoils, by generating lift through hydrofoils, can significantly reduce drag and improve energy efficiency. However, traditional propellers, such as propellers, are limited by cavitation effects and wake energy dissipation, leading to low efficiency. Straight-wing propellers offer advantages such as low cavitation risk, vector propulsion, simple structure, and low maintenance costs, but their integration with hydrofoil systems has not been fully explored.

[0003] Therefore, it is necessary to develop a composite vessel that combines a straight-wing propeller with a hydrofoil to improve overall performance. Utility Model Content

[0004] The purpose of this invention is to provide a composite vessel that combines a straight-wing propeller with a hydrofoil, thereby solving the problems of low efficiency and poor maneuverability of traditional vessels.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A composite vessel combining a straight-wing propeller and a hydrofoil includes a hull, a front wing assembly, a rear wing assembly, and a straight-wing propeller. The forewing assembly includes a foremast and a forehydrofoil. The foremast is connected to the fore-end of the hull, and the forehydrofoil is connected to the foremast. The aft wing assembly includes a rear mast and a rear hydrofoil. The rear mast is connected to the stern of the hull, and the rear hydrofoil is connected to one end of the rear mast. The straight-wing propeller is mounted on the front hydrofoil or the rear hydrofoil, preferably embedded in the sides of the rear hydrofoil to reduce drag.

[0006] Furthermore, the straight-wing thruster is a variable angle-of-attack vector propulsion mechanism, which can achieve 360° directional propulsion control.

[0007] Furthermore, the vessel includes multiple hydrofoils, with straight-wing propellers mounted on one or more hydrofoils as needed.

[0008] Furthermore, the mast is a hollow structure with internal wiring for connecting to the ship's control system and adjusting the hydrofoil pitch angle and the working status of the straight-wing propeller.

[0009] Furthermore, the ship uses a lithium-ion battery system as its power source.

[0010] The beneficial effects of this utility model include: 1. Hydrofoil structure greatly improves the energy utilization rate of the hull; 2. Straight-wing propellers provide sensitive steering and stable cruise capability; 3. The front and rear hydrofoil components work together to provide optimized power during takeoff, cruising, and docking. 4. Straight-wing propellers have a simple structure, low maintenance costs, and are suitable for shallow water areas. Attached Figure Description

Detailed Implementation

[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0013] Example 1 A composite vessel combining a straight-wing propeller and a hydrofoil, such as Figure 1 As shown, the hull includes a hull 1, a forward mast 2, a forward hydrofoil 3, a rear mast 4, a rear hydrofoil 5, and a vertical rotor 6. The forward hydrofoil 3 is connected to the front of the hull 1 via the forward mast 2, and the rear hydrofoil 5 is connected to the stern of the hull 1 via the rear mast 4. The vertical rotor 6 is embedded on both sides of the rear hydrofoil 5. The forward mast 2 and the rear mast 4 are hollow structures with internal wiring connected to a control system used to adjust the hydrofoil pitch angle and the operating status of the vertical rotor.

[0014] The hollow mast structure reduces the weight of the hull, and the hydrofoil pitch attitude can be directly transmitted to the hull's control system through the wiring in the hollow mast. The control system can also control the working status of the straight-wing propeller 6 through the wiring inside the rear mast 4.

[0015] Example 2 A composite vessel combining a straight-wing propeller and a hydrofoil, such as Figure 2As shown, the straight-wing propeller 6 is embedded on both sides of the front hydrofoil 5, and the rear hydrofoil 3 is connected to the stern of the hull 1 via the rear mast 2. Other structures are similar to those in Embodiment 1.

[0016] Example 3 A composite vessel combining a straight-wing propeller and a hydrofoil, such as Figure 3 As shown, straight-wing propellers 9 and 10 are installed on both the front hydrofoil 8 and the rear hydrofoil 11, for a total of four propellers, which are connected to the hull 1 via masts 7 and 12. This design provides stronger propulsion and control precision.

[0017] This invention achieves efficient and flexible ship propulsion through the coordinated action of a straight-wing propeller and a hydrofoil. The control system intelligently switches operating modes (start, cruise, berth) based on sensor data and performs real-time attitude adjustment and fault diagnosis.

[0018] The above embodiments are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art can make various modifications and improvements without departing from the spirit and scope of this invention.
