The General Electric LM5000 Marine Gas Turbine (see figure 1) intended for application to commercial and naval ships requiring high power (50,000 BHP nominal), high thermal efficiency (38 percent), and compact, marinized and relatively light weight prime movers is described. Ship candidates include Fast Support Ships, Aircraft Carriers [in a Combined Nuclear and Gas Turbine (CONAG) propulsion system], Battleships and large surface effect ships.
The LM5000 marine gas turbine is a marinized version of the LM5000 industrial gas turbine which was derived in 1977 from the CF6-50 aircraft engine. The CF6-6 model of this family of aircraft engines was the parent of the over 648 GE LM2500 marine gas turbine now used on the ships of 18 navies, 32 ship programs and 247 ships of the world. Over 2100 of the CF6-50 mode] engines are used on over 600 of the McDonald Douglas DC-10, the Airbus A300 and the Boeing 747 aircraft.
Since reliability and durability are dependent upon engine family experience, the hardware commonality with the CF6-50 aircraft engine is described as well as the associated experience, performance, installation and maintainability features.
