<h5>Reoptimize the propeller selection (including counter rotating propeller, guide propeller, fixed pitch propeller, controllable pitch propeller, etc.)</h5>
<h6>The propulsion efficiency can be increased by 5% - 8% by installing Tongzhou high-efficiency propeller</h6>
<em>● Improve efficiency and cavitation</em>
<em>● Suppression of tip flow</em>
<em>● Best match with the stern of the hull</em>
<em>● Comprehensive trade-offs of efficiency-vibration-cavitation etc.</em>

A high-efficiency propeller is a specialized type of propeller designed to maximize the propulsion efficiency of a vessel or aircraft. It is engineered to optimize thrust generation while minimizing energy loss, resulting in improved performance, fuel efficiency, and reduced emissions.
The design principles behind a high-efficiency propeller focus on several key factors:
1. Blade Shape: High-efficiency propellers are typically designed with carefully engineered blade profiles and twist distributions. These features minimize drag and maximize lift, allowing for better conversion of rotational energy into forward thrust.
2. Aspect Ratio: The aspect ratio of a propeller refers to the ratio of its blade length to its width. High-efficiency propellers often have higher aspect ratios, which reduce induced drag and improve overall efficiency by maximizing lift production.
3. Material Selection: Propellers made from lightweight, high-strength materials such as composite materials or advanced alloys can enhance efficiency by reducing the weight of the propeller. This decreases the rotational inertia, allowing for faster acceleration and deceleration of the propeller blades.
4. Surface Finish: The surface finish of a high-efficiency propeller is carefully controlled to minimize frictional drag. Smooth surfaces with low roughness reduce resistance and improve propeller efficiency.
5. Blade Pitch Control: Many high-efficiency propellers incorporate variable pitch control mechanisms. This allows the pitch angle of the propeller blades to be adjusted, optimizing performance across a wide range of operating conditions. Variable pitch control enables efficient operation at various speeds and load conditions, maximizing thrust while minimizing energy consumption.

A marine propulsion system refers to the set of components and mechanisms that enable a vessel to move through the water. It encompasses various technologies, including engines, propellers, transmissions, and control systems, all working together to generate thrust and propel the vessel forward.
At the heart of a marine propulsion system is the engine, which can be powered by diesel, gasoline, natural gas, or electricity. The engine converts fuel or electrical energy into mechanical energy, which drives the propulsion system. Different types of engines, such as diesel engines or gas turbines, may be used depending on the vessel's size, purpose, and power requirements.
The engine's power is transmitted to the propeller(s) through a transmission system, which may include gears, clutches, and shafts. The transmission adjusts and regulates the engine's rotational speed and torque to match the desired vessel speed and maneuverability.
The marine propeller, often the most visible and recognizable component of the propulsion system, converts the engine's rotational power into thrust. These propellers can vary in size, number of blades, and design configuration, all tailored to specific vessel requirements. Propellers can be fixed-pitch or controllable-pitch, with each offering distinct advantages in terms of efficiency, maneuverability, and performance.
In addition to the engine and propeller, modern marine propulsion systems utilize advanced control systems for optimal performance. These systems include electronic controls, sensors, and monitoring devices that regulate engine speed, monitor fuel consumption, optimize performance, and ensure the safety and reliability of the propulsion system.
Marine propulsion systems are designed to meet the specific needs of different vessels, such as merchant ships, naval vessels, cruise ships, ferries, fishing boats, and recreational boats. Each vessel type has unique requirements, such as speed, endurance, maneuverability, and fuel efficiency, which influence the selection and configuration of the propulsion system.
