Major efforts are currently underway to improve the fuel consumption efficiency of gas turbines for powering of U.S. Navy surface ships. Recent efforts have focused on efficiency improvement by the recovery of waste heat, in system enhancements such as the RACER (Rankine Cycle Energy Recovery) system. More recently, however, consideration is also being given to the use of a recuperator (and possibly an intercooler) to improve basic gas turbine thermal efficiency. Furthermore, a third approach is to improve efficiency by enhancements in basic gas turbine component technology. In this paper, current activity and progress in each of these three systems concepts are presented. First, the ship design benefits resulting from improved fuel efficiency will be described. Following this, programs in each of the above three categories are presented. This includes a general description of the hardware system, and the major performance characteristics. Finally, appropriate comparisons of these three approaches are made. These include projected fuel efficiency improvements, and the required ship space and weight. Projected future developments are also described.
