Optimising propulsion efficiency for naval platforms

免费看成年人视频在线观看Our expertise in designing and developing propellers around a large range of requirements spans more than 50 years.

Our Controllable Pitch, Fixed Pitch and Fixed Bolted Pitch options all ensure excellent hydrodynamic efficiency supporting overall vessel performance and stealth characteristics - perfected for naval operations.

Power, Robustness, Reliability

免费看成年人视频在线观看Successful and well-proven across the globe, our propellers are designed for robustness, reliability and efficiency, ensuring excellent cavitation performance as well as low vibration, noise levels and excellent fuel efficiency.

Our Controllable Pitch Propellers feature customised blade designs fully adapted to the ship’s wake. Designed to facilitate underwater blade change out, they are available for standard speeds (below 30 knots) and high speeds (above 30 knots).

Designed with ultimate stealth characteristics, our Fixed Pitch Propellers can be optimised to suppress cavitation, permitting high propulsive efficiency; vital characteristics for anti-submarine warfare.
