摘要
航空器燃油消耗的准确评估是航空公司降低飞行成本和控制燃油排放的重要手段。通过分析QAR实际飞行数据,拟合离场爬升阶段燃油消耗模型中气动参数之间的函数关系,并将侧风加入到燃油消耗评估模型中。对青岛机场离场爬升实验分析,采用改进的燃油消耗模型计算离场爬升阶段的燃油消耗量,结果比风洞实验计算精确度提高了3.6%,且考虑侧风的燃油评估实验结果中理论模型计算结果精确度为93.3%。
Accurate assessment of aircraft fuel consumption is an important means for airlines to reduce flight costs and control fuel emissions.By analyzing the actual flight data of QAR,the functional relationship between the aerodynamic parameters in the fuel consumption model of the departure climb phase is fitted,and the crosswind is added to the fuel consumption assessment model.Based on the analysis of the departure training of Qingdao Airport,the fuel consumption model of the exit climbing stage was calculated using the improved fuel consumption model.The results showed that the calculation accuracy of the wind tunnel experiment was improved by 3.6%,and the theory of the fuel evaluation experiment considering the crosswind was considered.The accuracy of the model calculation and QAR data is 93.3%.
