Six-Blade Propeller for Water-Jet Propulsion Systems

The Six-Blade Propeller for Water-Jet Propulsion Systems from JinYe Propeller is a nickel-aluminium bronze impeller-style propeller for water-jet units on high-speed vessels. The six-blade layout spreads load across the disk to reduce vibration, and the CFD-derived blade geometry is designed to limit cavitation and flow separation across the operating RPM range.

Key features

• Six-blade configuration with even load distribution and larger thrust surface than fewer-blade designs
• CFD-based pitch distribution for uniform flow and reduced cavitation at high speed
• Calibrated tip clearance and trailing-edge profiles to lower hydrodynamic noise
• Customizable pitch, diameter and section profiles, with engineering calculations supplied for each modification

Materials and manufacturing

• Ni-Al Bronze to Cu3 (CuAl10Fe5Ni5)
• Castings checked by ultrasonic and dye penetrant testing before machining
• 5-axis CNC machining to ISO 2768-m tolerances; CMM dimensional verification
• Precision-polished finish; optional coatings for abrasive water or extended dry storage
• Produced under ISO 9001 at a 20,000 m² facility

Technical data

• Blades: 6 (5-blade and custom configurations available)
• Rotation: clockwise / counter-clockwise
• Diameter and weight: per application
• Lead time: 4–6 weeks for custom-sized units
• Production capacity: 1000 units/month

Certifications

• Classification societies: DNV, ABS, RS, RINA, BV, KR, BKI, CCS; also offered with Lloyd's Register and ClassNK
• Management systems: ISO 9001, ISO 14001, ISO 45001

Applications

High-speed passenger vessels, coastal patrol craft, luxury yachts and workboats powered by marine diesels or gas turbines; designed for integration with most major water-jet system brands.
