摘要

Seaplanes have become an important tool along with rapidly developing technology in modern transportation for many countries related to sea. Considering the environmental evaluation for these aircraft, decreasing fossil fuels consumption and energy efficiency are important points for sustainability. For this purpose, in this study, first, the energy and exergy analyses based on the real data of a turboprop engine used in seaplane taken as the reference were performed. Then, new indicators developed for the sustainable propulsion index were examined and evaluated separately. The analyses were made for an altitude of 9000ft and three different dead state temperatures of -33 degrees C, -3 degrees C, and 27 degrees C. According to the analyses, while the average energy efficiencies were found to be 34.7%, 37.8%, and 40.7%, the average exergy efficiencies were found to be 19.24%, 21.25%, and 23.20%, respectively. In addition, the improvement potential due to irreversibility and entropy production for each case was also calculated and the results of the sustainable emission index were found to be very low. At the end of the study, the results were evaluated and some suggestions for the effective use of energy in the seaplanes were made.
