Propeller Milestone Achieved By U.S. Navy

The U.S. Navy's drive during the past decade to become more efficient on both the ship contracting and life cycle management sides has proven to be much more than mere talk. The "new" Navy is embodied in the current LPD-17 project, and U.S. Navy senior officers and engineers recently marked a critical milestone in ship research on January 6, 2000, wrapping up a successful phase in the testing of a full-scale propeller for the USS San Antonio (LPD-17) Class amphibious transport dock ship. The tests verify that a new compact design for the LPD-17 CPP meets the seven-year service life cycle requirements. The 17 million cycles completed at the ceremony show that this new design exceeds requirements and that the service life could be extended twofold. This Naval Sea Systems Command program could lead to a significant saving for the Navy in overhaul costs for the new propeller. The hub and blades, manufactured of nickel-aluminum-bronze and steel, constitute a unique design. The hub has a smaller diameter than in the past, leaving less surface for attaching the five blades and increasing stress in the blade root area and the hub. Verifying the new design will facilitate extending the period between overhauls from seven to 14 years, producing lower costs, easier maintenance and faster upgrades — an affordable propeller with enhanced performance reflecting the fiscal constraints of the modern Navy.
