航空发动机全生命周期碳排放计量方法研究

Study on measurement method of aero-engine life cycle carbon emission

航空产业是碳排放八大重点行业之一,航空产业的碳排放主要受航空发动机碳排放的影响,因此亟需开展航空发动机碳排放计量方法研究。以生命周期评价作为航空发动机碳足迹的量化方法,将航空发动机全生命周期碳排放分为燃料周期碳排放与材料周期碳排放,并分别进行统计;将航空发动机系统边界进行划分,对各个阶段进行数据收集,并对数据做出要求,得到一套相对完整的航空发动机碳排放计量方法。本文得到的方法可以从生命周期的角度全面评估航空发动机碳排放,能够为航空发动机全生命周期碳排放计量提供指引,从燃料角度与材料角度为减排提供理论基础。

Aviation industry is one of the eight key industries of carbon emission.The carbon emission of aviation in-dustry is mainly affected by the carbon emission of aero-engine.Therefore,it is urgent to carry out the research on the measurement method of aero-engine carbon emission.The life cycle assessment is used as a quantitative meth-od for the carbon footprint of aero-engines.The life cycle carbon emissions of aero-engines are divided into fuel cy-cle carbon emissions and material cycle carbon emissions,and statistics are carried out separately.The aero-engine system boundary is divided,the data collection that should be carried out in each stage is proposed,and the data is required.A relatively complete set of aero-engine carbon emission measurement method is obtained.The method obtained in this paper can comprehensively evaluate the carbon emissions of aeroengines from the perspective of life cycle,which can provide guidance for the measurement of carbon emissions of aeroengines throughout the life cy-cle,and provide a theoretical basis for emission reduction from the perspective of fuel and material.
