Waterjet propulsion solutions：喷水推进解决方案.pdf

Waterjet propulsion solutions Wärtsilä designs waterjet propulsion systems for the commercial, military and superyacht market. A unique welded modular jet construction is used that makes it possible to offer competitive solutions in stainless steel as well as custom solutions in every power range and in every form and execution. In close co-operation with a limited number of partners, experienced in building welded constructions in stainless steel and titanium for the marine and nuclear power industries, we are developing the future of waterjet propulsion. The waterjet range starts at around 500 kW. Every LIPS® jet is optimized using Computational Fluid Dynamics (CFD) calculations based on the design details and operating profile of the vessel. The result is the standard of excellence in performance and reliability that our markets expect. Propulsion solutions with waterjets Waterjets propulsion is the most successful and efficient method cruising condition, resulting in improved efficiency, low noise of propulsion for high-speed applications. The advantages are and vibrations and a smaller propeller diameter. not only higher efficiency, but also lower vessel resistance due to Looking for excellent manoeuvrability at all vessel speeds and the absence of underwater appendages like shafts, rudders and fast turn-around times? Waterjets outperform almost every shaftstruts. The absence of any parts below the waterline also propulsion alternative. With catamarans it is usually possible to makes waterjets an ideal solution for shallow water operation. achieve pure sideways movement and 360 degree turning The unique design features of the Lips jet will ensure access to without a bow thruster. even the smallest ports. Hybrid propulsion systems - the use of two fixed or controllable pitch propellers in combination with a centre waterjet - combine the best of both worlds. The propellers are
