Claim 18:
19. A system, comprising:
a controller having a processor, a memory, and instructions stored on the memory and executable by the processor to:
control combustion in a combustor to generate a combustion gas flow that flows through a turbine stage along a combustion gas path disposed between a turbine shaft and a turbine casing of a gas turbine, wherein the turbine shaft is disposed along a rotational axis, the turbine casing is disposed circumferentially about the turbine shaft, and the turbine stage comprises a plurality of turbine vanes disposed upstream from a plurality of turbine blades; and
control an isothermal expansion system coupled to the turbine stage to vary axial positions of combustion within the turbine stage to reduce temperature variations over the turbine stage at least by varying one or more parameters of fluid injection from a plurality of fluid injectors on the respective plurality of turbine vanes, wherein the isothermal expansion system comprises a plurality of flame stabilizers disposed in different axial positions over an axial length between leading and trailing edges of the plurality of turbine blades, wherein at least one of the plurality of flame stabilizers is coupled to each of the plurality of turbine blades.
