Claim 13:
14. The method of claim 13, further comprising
selecting a second turbine stage from the set of standard turbine stages based on a first predetermined power demand of the turbine for the first gas turbine engine, wherein the second turbine stage is any turbine stage from the set of standard turbine stages that is greater in size than the selected initial turbine stage for the first gas turbine engine,
selecting a second turbine vane ring from the subset of standard turbine vane rings included in the second turbine stage for the first gas turbine engine based on exit conditions of the initial turbine stage of the turbine for the first gas turbine engine,
locating the second turbine vane ring downstream of the initial turbine stage in the first gas turbine engine, and
locating a second turbine rotor associated with the second turbine stage downstream of the second turbine vane ring in the first gas turbine engine.
