Abstract This paper deals with the performance analyses of exergetic, exergoeconomic, sustainability and environmental damage cost for J85 turbojet engine at Idle (ID), Intermediate (INT), Military (MIL) and Afterburner (AB) operation modes. The exergetic efficiency of whole engine is calculated to be 0.24 % at ID, 18.67 % at INT, 29.81 % at MIL and 22.77 % at AB modes, respectively. The unit exergy cost of product is accounted to be 30,423.94 $/GJ at ID, 269.35 $/GJ at INT, 121.47 $/GJ at MIL and 133.47 $/GJ at AB modes. The sustainable cost index is found to be 30,350.92 $/GJ at ID, 224.45 $/GJ at INT, 85.26 $/GJ at MIL and 103.0 $/GJ at AB modes while the sustainability index is obtained to be 1.0 at ID, 1.2 at INT, 1.43 % at MIL and 1.3 at AB modes. On the other hand, the environmental damage cost rate of engine are calculated to be 180.22 $/h at ID, 271.34 $/h at INT, 657.95 $/h at MIL and 1992.55 $/h at AB modes while the total cost rates of engine are determined to be 974.07 $/h at ID, 1357.15 $/h at INT, 2641.76 $/h at MIL and 6573.04 $/h at AB modes, respectively. The results indicate that J85 engine operates the exergetic-efficiently and cost-effectively at MIL mode.

带加力燃烧室的 J85 涡轮喷气发动机的耗能、耗能经济、可持续性和环境损害成本分析

摘要 本文涉及 J85 涡轮喷气发动机在怠速 (ID)、中级 (INT)、军用 (MIL) 和加力 (AB) 运行模式下的火用、火用经济、可持续性和环境损害成本的性能分析。经计算,整个发动机的火用效率分别为 ID 时 0.24%、INT 时 18.67%、MIL 时 29.81% 和 AB 模式时 22.77%。产品的单位火用成本在 ID 下为 30,423.94 美元/GJ,在 INT 下为 269.35 美元/GJ,在 MIL 下为 121.47 美元/GJ,在 AB 模式下为 133.47 美元/GJ。可持续成本指数在 ID 处为 30,350.92 美元/GJ,在 INT 处为 224.45 美元/GJ,在 MIL 处为 85.26 美元/GJ,在 AB 模式处为 103.0 美元/GJ,而获得的可持续性指数在 ID 处为 1.0,在处为 1.2 INT,MIL 为 1.43 %,AB 模式为 1.3。另一方面,发动机的环境损害成本率计算为180。ID 为 22 美元/小时,INT 为 271.34 美元/小时,MIL 为 657.95 美元/小时,AB 模式为 1992.55 美元/小时,而发动机的总成本率确定为 ID 为 974.07 美元/小时,1357.15 美元/小时在 INT,MIL 下为 2641.76 $/h,AB 模式下分别为 6573.04 $/h。结果表明,J85 发动机在 MIL 模式下运行高效且具有成本效益。
