Nautican Component
High Efficiency Nautican Nozzles
Airfoil-profile propeller nozzle built from thirty-six airfoil sections with a 316L stainless steel inner surface, for tugs, fishing vessels and other work vessels.
Description
The High Efficiency Nautican Nozzle differs from conventional nozzles in its cross-sectional profile, which was designed to maximize performance rather than ease of construction. It is manufactured from thirty-six airfoil sections optimized for turbulent flow.
Key features
- Entire inside surface of 316L stainless steel, eliminating welding repairs at the interior ring common on conventional nozzles
- Can be supplied with integrated Pre-Swirl Stators
- Reported sea trial results: fuel-efficiency gains of up to 30 percent, speed gains of up to two knots, and bollard-pull gains of up to 60 percent over an open propeller or 12 percent over conventional nozzles
Applications
Tugboats, fishing vessels, cable ships, cruise ships and yachts.
