... and their relationships in the design process is presented in detail. Based on the data model, the entire engine predesign process is presented. Starting with the definition of a flight mission scenario and resulting top level engine requirements, thermodynamic engine performance models are developed. By means...

... Power systems Thermodynamics Solid oxide fuel cell/gas turbine (SOFC/GT) hybrid system has the obvious merits of high efficiency, zero emission, and fuel flexibility, which is one of the most promising energy dynamic technologies in the future energy market [ 1 , 2 ]. Since this kind of hybrid...
