In this study, environmental and enviroeconomic analyses regarding two different turbofan engine families that are commonly used in commercial aircrafts are carried out at Landing and Take-Off (LTO) cycle involving take-off, climb-out, approach and idle phases. For this aim, HC, CO, NO_X and CO₂ emissions of family 1 (F1) and family 2 (F2) engines are taken into consideration over the course of LTO cycle based on International Civil Aviation Organization (ICAO) emission database. The average thrust values of these engines are 115.12 kN for F1 engines and 123.77 kN for F2 engines. Global Warming Potential (GWP) and enviroeconomic cost factor (ECF) for the each engine are calculated. Also, to predict GWP and ECF parameters, these metrics are modelled based on by-pass ratio and overall pressure ratio. According to the results of the study, the average GWP value of F1 and F2 engines are obtained as 2256.17 kg_CO₂/day_cycle and 1779.02 kg_CO₂/day_cycle, respectively. On the other hand, the average enviroeconomic cost factor (ECF) of F1 and F2 engines are computed as 261.71 Euro/day_cycle and 206.36 Euro/day_cycle, respectively. Finally, accuracy of GWP model is achieved with R² = 0.9956 for F1 engines and R² = 0.9664 for F2 engines. The relatively low R² of the model for F2 engines could be attributed to effects of different types of the combustor. It is seemed that the present analysis allows to predict the average environmental effect and economic cost of the aircraft engines in service.

在这项研究中，在涉及起飞、爬升、进近和怠速阶段的着陆和起飞 (LTO) 循环中，对商用飞机中常用的两种不同涡扇发动机系列进行了环境和环境经济分析。为此，HC、CO、NO _X和 CO ₂根据国际民用航空组织 (ICAO) 排放数据库，在 LTO 循环过程中考虑了系列 1 (F1) 和系列 2 (F2) 发动机的排放。这些发动机的平均推力值 F1 发动机为 115.12 kN，F2 发动机为 123.77 kN。计算每个发动机的全球变暖潜能值 (GWP) 和环境经济成本系数 (ECF)。此外，为了预测 GWP 和 ECF 参数，这些指标基于旁路比和总压力比建模。根据研究结果，F1和F2发动机的平均GWP值为2256.17 kg_CO ₂ /day_cycle和1779.02 kg_CO ₂/day_cycle，分别。另一方面，F1 和 F2 发动机的平均环境经济成本因子 (ECF) 分别计算为 261.71 Euro/day_cycle 和 206.36 Euro/day_cycle。最后， F1 发动机的R ² = 0.9956 和 F2 发动机的R ² = 0.9664实现了 GWP 模型的准确性。F2 发动机模型的相对较低的 R ²可归因于不同类型燃烧器的影响。目前的分析似乎可以预测服役中的飞机发动机的平均环境影响和经济成本。
