As the core component of the ship propulsion system, marine propellers have various types and designs to meet the needs of different ships. They are mainly divided into fixed pitch propellers (FPP) and controllable pitch propellers (CPP). Fixed pitch propellers are simple in design and suitable for small and medium-sized ships with relatively stable sailing conditions. The pitch of the blades is fixed and cannot be adjusted. The adjustable pitch propeller adjusts the blade angle through a hydraulic or electric system, which can provide optimal performance under different speed and load conditions. It is particularly suitable for large ships that require frequent speed changes, stoppages and reverse propulsion operations.

Propellers are usually made of high-strength, corrosion-resistant materials such as bronze, aluminum alloys and stainless steel to ensure their long life and high durability in the marine environment. Advanced casting and processing technologies can ensure the high precision and surface finish of the propeller, thereby reducing underwater friction and improving propulsion efficiency.

In order to further improve the propulsion performance and fuel efficiency of ships, manufacturers also provide overall propulsion system integration services, including components such as main engines, transmission systems and propellers. These integrated systems are optimized to achieve higher energy utilization and lower operating costs. In addition, some manufacturers provide customized services to tailor the size, shape and material of propellers according to the design requirements and operating environment of specific ships to ensure the best match with the hull.
