One approach to substantially improving gas turbine thermal efficiency is to replace the nearly constant pressure combustion process (in fact there is generally a 4 to 5 percent reduction in total pressure during combustion in a gas turbine) with some form of pressure-gain heat release such as either a constant volume or detonative mode of combustion.
