Size: Custom-designed based on vessel requirements, typically ranging from 0.5m to 10m in diameter.
Grade: Marine-grade alloys (e.g., NiAl bronze, stainless steel) or composite materials for specialized applications.
Viscosity: Optimized for operating fluid (seawater or freshwater) with dynamic viscosity considerations (1.0-1.5 cP for water).
Buoyancy: Neutral or negative buoyancy depending on material density (7.8-8.8 g/cm³ for metals, 1.2-1.8 g/cm³ for composites).
Material: High-strength corrosion-resistant alloys (e.g., CuNi, Al bronze) or advanced composites (carbon fiber-reinforced polymers).
Blade Count: 3 to 6 blades, tailored for efficiency and cavitation avoidance.
Pitch: Adjustable or fixed, optimized for specific RPM and thrust requirements.
Surface Finish: Polished or coated (e.g., antifouling, erosion-resistant coatings) for hydrodynamic efficiency.
Load Capacity: Designed for thrust ranges from 1 kN to 500+ kN, depending on application.
Operational RPM: Typically 50-1500 RPM, optimized for fuel efficiency and noise reduction.
