摘要

航空物流运输过程中会产生一些对环境造成污染的污染物,为了降低航空物流运输中发动机排放的污染物,需要对飞机的发动机进行实时监控。首先需要计算飞机物流运输所形成的年排放量,然后利用两相紊流燃烧理论对发动机污染物排放进行数值模拟,完成对航空物流运输过程中污染物排放量的计算,最后通过实验分析发动机部件退化对发动机排放污染物的影响,根据得出的具体数值,一旦发现排放污染物有增多的趋势,及时修理发动机中出现退化的部件,降低由航空物流运输造成的环境污染。
        In the process of air logistics transportation,some environmental pollutants will be generated. In order to reduce the pollutants emitted by the engine in the air logistics transportation,it is necessary to monitor the engine of the aircraft in real time. Firstly,it is necessary to calculate the annual emissions formed by aircraft logistics transportation,and then use the two-phase turbulent combustion theory to numerically simulate the engine pollutant emissions,complete the calculation of pollutant emissions in the process of aviation logistics transportation,and finally analyze the engine components through experiments. The impact of degradation on engine emissions is based on the specific values obtained. It aims to conduct timely repair of degraded components in the engine and reduce environmental pollution caused by air logistics once the emission of pollutants is found to increase.
