This research is focused on analysing the thermodynamic performance results of the GE90 turbofan engine with different fan pressures and bypass air ratios. The paper analyses thrust force, thrust efficiency, thrust power, specific fuel consumption, heat input, fuel flow rate, fuel cost rates, emission amount, and cost. Accordingly, the thrust force of the turbofan engine increased as the fan pressure ratio increased, and the highest FBR is obtained as: 1.98 = 573.98 kN. While the highest thrust efficiency value is obtained at 37.22% at the FPR:1.66-BPR:7.4 ratios, the energy efficiency reached its maximum at 45.91% at the same values at the FPR:1.66-BPR:7.4 ratios. At the same rates, specific fuel consumption is calculated as 27.87 kg/kN.h, with its lowest value. The emission release amount of the turbofan engine and the cost of this amount are 49.48 tonCO2/h and 74.21 $/tonCO2.h at the highest FPR:1.98-BPR:4.4 rates.

Bu araştırma, farklı fan basınçları ve baypas hava oranları ile GE90 turbofan motorunun termodinamik performans sonuçlarının analizine odaklanmıştır. Analizde itme kuvveti, itme verimliliği, itme gücü, özgül yakıt tüketimi, ısı girişi, yakıt akış hızı, yakıt maliyet oranları, emisyon miktarı ve maliyet analiz edilmiştir. Buna göre, turbofan motorunun itme kuvveti, fan basınç oranı arttıkça artmış ve en yüksek FBR; 1,98 = 573,98 kN olarak elde edilmiştir. En yüksek itme verimliliği değeri FPR:1,66-BPR:7,4 oranlarında %37,22 ile elde edilirken, enerji verimliliği aynı değerlerde FPR:1,66-BPR:7,4 oranlarında %45,91 ile maksimum değerine ulaşmıştır. Aynı oranlarda özgül yakıt tüketimi en düşük değeri ile 27,87 kg/kN.h olarak hesaplanmıştır. Turbofan motorunun emisyon salınım miktarı ve bu miktarın maliyeti en yüksek FPR:1.98-BPR:4.4 değerlerinde 49.48 tonCO2/h ve 74.21 $/tonCO2.h olarak gerçekleşmektedir.
