Previously reported performance of the PDTE cycles and commercial gas turbine engines are compared to an ideal Brayton cycle. This comparison is extended to form a new performance metric combining the effect of combustor pressure increase and turbine efficiency. The PDTE design space including compressor pressure ratio, combustor heat addition, combustor pressure loss, and turbine efficiency is explored to determine the effect of these variables on the proposed definition. The primary benefit of the proposed definition over those considered previously is that by combining the combustor and turbine efficiencies the difficulties associated with determining the unsteady turbine inlet state are avoided in favor of using the steady compressor discharge state.Read More
