FARKLI FAN BASINCI VE BYPASS ORANLARINDA TURBOFAN MOTORUNUN TERMODİNAMİK PERFORMANSININ İNCELENMESİ BÖLÜM A: ENERJİ ANALİZİ

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.
