航空发动机全生命周期碳排放计量方法研究

航空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，提出各个阶段应进行的数据收集，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，可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。

Study on Measurement Method of Aeroengine Life Cycle Carbon Emissions

Aviation is one of the eight key industries of carbon emission. The carbon emission of aviation industry 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 method for the carbon footprint of aero-engines. The life cycle carbon emissions of aero-engines are divided into fuel cycle 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. This paper obtains a relatively complete set of aero-engine carbon emission measurement methods. This method comprehensively evaluates 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 cycle, and provide a theoretical basis for emission reduction from the perspective of fuel and material.
