This paper analyzes and evaluates exergetic improvement rate (IPex) of the components of a small turbojet engine with various turbine inlet temperatures. 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.
