16. A method for operating a gas turbine engine including an inlet end, a compressor including a compressor rotor assembly with a plurality of compressor disk assemblies adjacent the inlet end, a combustor adjacent the compressor, a turbine including a turbine rotor assembly with a plurality of turbine disk assemblies adjacent the combustor, an exhaust end adjacent the turbine, a first shaft end adjacent the exhaust end and coupled to at least one of the plurality of turbine disk assemblies and a first driven apparatus, and a second shaft end adjacent the inlet end and coupled to the compressor rotor assembly, at least one of the plurality of turbine disk assemblies, and a second driven apparatus, the first shaft end and the second shaft end being located at opposite ends of the gas turbine engine, the method comprising:
-
driving the first driven apparatus and the second driven apparatus concurrently with the gas turbine engine at a predetermined load; increasing a second load output to the second driven apparatus coupled to the second shaft end when a first load output to the first driven apparatus coupled to the first shaft end is decreased to maintain the gas turbine engine output at the predetermined load; and decreasing the second load output to the second driven apparatus when the first load output to the first driven apparatus is increased to maintain the gas turbine engine output at the predetermined load. - View Dependent Claims (17, 18, 19, 20)
