Marine 4 Blade Propeller


About product

A marine 4-blade propeller is a specialized propeller designed for larger vessels like tugboats and container vessels. It features four robustly constructed blades that are strategically shaped and positioned on a central hub.

  • Kaplan Blade: Offers adjustable pitch for optimizing performance in varying conditions.
  • MAU (Modularly Adjustable Underwater) Blade: Provides versatility and adaptability with adjustable pitch and rake angles.
  • B-series Blade: Ensures optimal thrust generation and efficiency for fixed-pitch propellers.
  • Commonly used in tugboats and commercial ships for precise maneuverability and efficient propulsion.

The Blade Type Of Marine 4 Blade Propeller

The marine 4-blade propeller can be found in different blade types, including Kaplan, MAU (Modularly Adjustable Underwater), and B-series propellers. Here’s a brief description of each blade type:

  • Kaplan Blade: The Kaplan blade design is commonly used in marine propellers, known for its adjustable pitch feature. It consists of blades with a controllable pitch angle that can be adjusted to optimize performance based on varying vessel speeds and operating conditions. The Kaplan blades have a sleek, slender shape with a higher aspect ratio, making them efficient in both propulsion and energy conversion. They are often used in applications where a wide range of speed variations is required, such as tugboats and some container vessels.
  • MAU (Modularly Adjustable Underwater) Blade: The MAU blade is a type of propeller blade that offers versatility and adaptability. It consists of blades that can be adjusted both in pitch and rake angle, allowing for fine-tuning of the propeller’s performance. The MAU blade design enables efficient propulsion in different operating conditions and vessel requirements. This blade type is commonly used in ships like tugboats, where precise maneuverability and power optimization are crucial.
  • B-series Blade: The B-series blade is a specific type of blade design commonly used in fixed-pitch propellers for various marine applications. B-series blades have a robust, sturdy construction and are designed to provide optimal performance in terms of thrust generation and efficiency. They are often used in commercial ships, including some tugboats and container vessels, where a fixed-pitch propeller is preferred.
