A LOOK AT THE DESIGN VALIDATION PROGRAM OF THE LHA-1 PROPULSION SYSTEM

This paper describes the history, background, instrumentation methods, and results of validating the LHA (Class Ship) propulsion system. Total use of a specially instrumented main machinery space and data collection at sea are unique ways of meeting U.S. Navy specification requirements at Ingalls Shipbuilding Division. Automatic and manual data collection and computer analysis were applied to prove the characteristics of this large (twin propeller) steam propulsion plant. The LHA (general purpose assault ship) has two boilers, the largest of any in current naval service, each generating approximately 200 tons of steam per hour. Propulsion turbines develop a total of 70,000 horse power to provide speeds in excess of 20 knots. Full scale performance testing during actual operations were conducted throughout the manufacturing process and were concluded on Navy Acceptance Trial.
