Innovative Gas-Turbine Engine Cycles

The focus of recent research has been to increase the power and thermodynamic efficiency of a gas turbine engine through the use of multiple inter-stage burners (MIBs).   An extension to previous inter-stage turbine burner research including turbine cooling for multiple inter-stage burner engines was performed and results show large performance improvements for land-based power production engines.   Furthermore, land-based engine performance may be significantly increased by adopting open-loop or closed-loop steam cooling in conjunction with MIBs.   Comparisons of the performance, in terms of net output power and thermodynamic efficiency of these engines with open-loop air cooling, open-loop steam cooling and closed-loop steam cooling, are shown below.
