Abstract: In this paper, component-based exergetic assessment is presented for an experimental turboprop/turboshaft engine, including comparisons and exergetic performance such as their efficiencies, improvement potentials, exergy destruction rates, relative exergy destructions, fuel depletion ratios, productivity lacks, and fuel and product exergy factors with different power settings and torques. The exergetic assessment of the engine components provided here should be helpful for designing shaft-power aero engines. Results from this study also evaluate effects of the operating parameters on the exergetic performance of the engine components commonly used in regional propeller aircrafts and helicopters.

Keywords: turboprop engines; propeller aircraft; helicopters; exergy analysis; propulsion; turboshaft; regional aircraft; aero engines; engine design.
