The performance of various split-turbine configurations based on the General Electric Company LM-2500 gas turbines is investigated with the aid of a component-matching computer program. The program was derived and uses component data from a gas turbine program for the LM-2500 which was produced by the General Electric Company. Split-turbine configurations with maximum power potential of 40,000, 50,000, and 60,000 horsepower nominal per shaft for two-shaft configurations and part-power configurations of 20,000 horsepower nominal per shaft were investigated. The investigation showed that the components were well matched and resulted in fuel consumption comparable with the basic LM-2500 gas turbine at the high power levels. At the part-power level below 20,000 horsepower the component matching is more difficult, and the split-turbine fuel consumption is slightly higher than that of an equivalent LM-2500 gas turbine.
