对一台小型涡喷发动机燃用常规航空燃料和生物燃料进行了热力学性能和火用经济学分析，并对发动机的性能和费用流进行了评估。通过基于组件的火用和成本计算进行分析。发动机的主要部件是空气压缩机、燃烧室和高压涡轮机。结果表明，在生物燃料试验工况下，压气机、燃烧室和高压涡轮机的（火用）效率分别为74.52%、47.68%和99.00%.另一方面，当发动机供给常规航空喷气燃料时，空气压缩机、燃烧室和高压涡轮机的（火用）效率分别计算为75.22%、48.34%和98.44%。此外，推力的成本率计算为79.08 US$/h·kN的喷气燃料的情况下和91.89 US$/h·kN的生物燃料的测试情况。
Exergetic performance and exergoeconomic analyses of a small-scale turbojet engine fuelled with either conventional aviation fuel or biofuel are conducted; and the performance and cost flow of the engine are assessed. The analyses are performed through component-based exergy and cost calculations. The main components of the engine are the air compressor, the combustion chamber and the high-pressure turbine. The results show that the exergy efficiencies of the engine components are obtained as 74.52% for the air compressor, 47.68% for the combustion chamber, and 99.00% for the high-pressure turbine for the biofuel test case. On the other hand, when the engine is fed with the conventional aviation jet fuel, the exergy efficiencies of the air compressor, the combustion chamber, and the high-pressure turbine are calculated as 75.22%, 48.34% and 98.44%, respectively. In addition, the cost rate of thrust is calculated as 79.08 US$/h·kN for the jet fuel case and 91.89 US$/h·kN for the biofuel test case.
