基于燃料属性的航空器全航线碳排放预测
Prediction of Civil Aircraft Carbon Emissions in Entire Flight Route Based on Fuel Properties
摘要
Abstract
Accurate calculation of carbon emissions is the prerequisite for advancing the green development of civil aviation and conducting carbon reduction work.To accurately predict aircraft carbon emissions and assess the impact of fuel property on the emissions,a calculation method based on the jet fuel properties,aircraft flight mechanics model and aeroengine model is proposed.This method takes into account the different flight characteristics of aircraft during landing and take-off cycle as well as airborne flight phase.Using this method,the carbon emissions of aircraft along the entire route are calculated,and the accuracy of the method is validated by comparing with the results obtained from ICAO carbon emissions calculator methodology.The impact of flight conditions and fuel property on carbon emissions is analyzed.The results indicate that reducing take-off weight and increasing cruise altitude are beneficial for reducing aircraft carbon emissions.The use of bio-jet fuel has a relatively minor impact on flight route carbon emissions but can effectively reduce emissions over the lifecycle.Compared with traditional flight carbon emissions prediction methods,the introduction of fuel properties enhances the applicability of carbon emission calculation and improves the prediction accuracy.关键词
