Propeller blades are rotating airfoils that convert engine power into thrust for marine propulsion. Their design, including pitch and shape, optimizes efficiency and maneuverability in water. They are crucial for the movement and speed control of ships and boats.
Size: Typically ranges from 0.5 to 10 meters in diameter, depending on vessel type.
Grade: Often classified by ISO 484/1 or ASTM A148 standards for marine propellers.
Viscosity: N/A (propeller blades are solid components; viscosity applies to fluids).
Buoyancy: Neutral or slightly negative buoyancy to avoid cavitation and ensure stability.
Material: Commonly made from bronze alloys (e.g., nickel-aluminum bronze), stainless steel, or composite materials.
Blade Count: Typically 3 to 6 blades, depending on efficiency and noise requirements.
Pitch: Adjustable or fixed, measured in degrees or inches per revolution.
Surface Finish: Polished to reduce drag and improve hydrodynamic efficiency.
Corrosion Resistance: High, due to marine-grade materials and protective coatings.
Load Capacity: Designed to withstand thrust forces up to several tons, depending on size and application.
Yes, Propeller Blades for Marine Propulsion typically comply with maritime standards such as ISO 484, ABS, DNV, and other classification society requirements.
