飞机性能下降导致燃油消耗增加。这导致更高的排放，并且在分析整个生命周期时是一个重要因素。目前该领域的研究并没有量化飞机生命周期中的退化排放。本文的目的是提出一种确定涡轮风扇飞机寿命周期内二氧化碳排放量的方法。特别注意的是退化和适当和及时的维护作为控制这些排放的一种方式的重要性。退化对涡轮风扇飞机的二氧化碳排放起着重要作用。生命周期由八个序列建模。本文对使用和修理寿命序列提出了一种新的数学解释。在使用循环中，分别计算了气动结构退化和发动机退化引起的排放。所提出的方法在四架涡扇飞机上实施，并在八架涡扇飞机上进行了测试。结果表明，99%以上的二氧化碳排放发生在使用序列中。降解（空气动力学结构和发动机）造成的排放占二氧化碳排放总量的3.6%至6.4%。作者提出了一种新的方法来减少由降解引起的排放。
Aircraft performance degradation causes higher fuel consumption. This results in higher emission and it is an important factor when the complete life cycle is analyzed. Current research in the field doesn’t quantify degradation emissions in the life cycle of an aircraft. The objective of this paper is to suggest a methodology for determining carbon dioxide emission during the life cycle of turbofan aircraft. Special attention is given to degradation and the importance of proper and timely maintenance as a way of controlling these emissions. Degradation plays a significant role in the carbon dioxide emission of turbo fan aircraft. The life cycle was modeled by eight sequences. In this paper a new mathematical interpretation is suggested for following life sequences: use and repair. In the use cycle, emission caused by aerodynamic structure degradation and engine degradation is calculated separately. The proposed methodology was implemented on four and tested on eight turbofan aircraft. Results show that more than 99% of carbon dioxide emission occurs in the use sequence. The emission caused by degradation (aerodynamic structure and engine) makes up between 3.6% and 6.4% of total carbon dioxide emission. A novel methodology for reducing emission caused by degradation is proposed by the authors.
