New Waterjets Could Propel LCS to Greater Speeds | |
| <<TIMEWATCHER>> Offer Upgrade  User ID: 32911015  United States02/07/2013 04:54 AM Report Abusive Post Report Copyright Violation | The Navy's fifth Littoral Combat Ship (LCS), Milwaukee, will be the first to benefit from new high-power density waterjets aimed at staving off rudder and propeller damage experienced on high-speed ships. The product of an Office of Naval Research (ONR) Future Naval Capabilities (FNC) program, the waterjets arrived last month at the Marinette Marine shipyard in Wisconsin, where Milwaukee (LCS 5) is under construction. "We believe these waterjets are the future," said Dr. Ki-Han Kim, program manager in ONR's Ship Systems and Engineering Research Division. "Anything that we can do to keep ships ready to go will ultimately benefit our warfighters." Chief of Naval Operations Adm. Jonathan Greenert's 2013-2017 Navigation Plan calls for fielding improved ships to support counterterrorism and irregular warfare missions at sea and ashore. The LCS will play a big role in the Navy's plan as a modular, adaptable vessel for use against diesel submarines, littoral mines and attacks by small surface craft. Developed by Rolls-Royce Naval Marine in Walpole, Mass., in collaboration with ONR and Naval Surface Warfare Center, Carderock Division, the new Axial-Flow Waterjet Mk-1 can move nearly half a million gallons of seawater per minute, providing more thrust per unit than current commercial waterjets. Four of the new waterjets will propel the LCS to speeds greater than 40 knots. Researchers believe the smaller, more efficient waterjets will help the LCS avoid excessive maintenance costs associated with cavitation - a phenomenon that occurs when changes in pressure create air bubbles on rotating machinery, such as marine propellers. Repeated occurrences can cause whole chunks of metal to wear away, leading to frequent repairs and replacements. The waterjets' new design could increase their lifespan between repairs. The FNC program that oversaw development of this technology proved to be as adaptable as LCS. The waterjets originally were slated to benefit another ship program that was discontinued. Instead of cancelling the waterjets program, officials regrouped and shifted their focus to designing a product that would improve the performance of LCS.
