The engine consists of an inlet starter generator a centrifugal compressor a reverse flow combustion chamber an axial-flow turbine and an exhaust nozzle. IPex analysis is performed on this turbomachinery utilizing kerosene as a fuel. Exergetic analysis is applied to the turbojet to investigate the turbine inlet temperature effects (i.e. turbine material improvement) on the IPex of each component in the engine using different turbine inlet temperatures at a constant reference environment. © 2017 Elsevier B.V.
