SAGE模型在民航发动机排放中的应用研究

SAGE Model Analysis and Application in Civil Aviation Engine Emission

在日益关注排放尤其是航空排放的当代社会,Aero2k和SAGE模型应运而生,且SAGE模型的优势更为明显。对SAGE模型的起源和模型的功能做了简单的介绍,并详细分析了SAGE模型的计算模块。通过对SAGE模型计算航空排放的过程分析,设计了排放计算流程图,并将其编成了软件。利用该软件对某些航班计算出的排放量与实际值相差不大,从而证明了SAGE模型和该软件的可行性,并通过计算出的数据初步发现了排放量和燃油消耗量与发动机类型之间的联系,也为全面评估和预测某航空公司乃至全国的航空排放奠定了基础。

Aero2k and SAGE model have been developed in the contemporary society when emissions attract extensive attention, especially on aviation emissions. In this paper, origin and fnnetions of SAGE model are introduced simply, while its calculation model is analyzed in detail. Based on SAGE model, process analysis of calculating aviation emissions has been made and calculation procedure has been designed, then software about calculation of aviation emissions has been developed according to the procedure. There is no much deviation between true values and results based on the software, which is a good proof of feasibility of the software, with preliminary relation between emissions, fuel burn and types of engines being found, and has lay a foundation for comprehensive assessment and prediction on aviation emissions of some airline even of the entire nation.
