Abstract: Takeoff is a very important stage in the flighting process. To study the influence of thrust on fuel consumption and emission, this paper focuses on a coupled takeoff fuel consumption calculation method based on various data. Taking the B738, A320, A321, and B737 as the research objects, this paper compared the fuel consumption calculation results of different methods during takeoff, analyzed the influence of takeoff thrust on fuel consumption and emission, and compared the changes of takeoff emissions after thrust adjustment. The results show that the proposed method in this study has high accuracy. Compared with the real data, the average relative differences of takeoff fuel consumption for the four types of aircraft are respectively -2.32%, 5.41%, 2.31% and -3.80%. For B738 and B737, the takeoff fuel consumption first decreases and then increases with the increase of thrust. When the thrust is 77% and 81%, the takeoff fuel consumption is the lowest. For the aircraft A320, takeoff fuel consumption decreases with the increases of the takeoff thrust. However, for the aircraft A321, the fuel consumption increases with the increases of the takeoff thrust. With the thrust adjustment, the annual takeoff emissions of the four types of aircraft inGuangzhou Baiyun airport can be reduced by 2499.3 tons, with a reduction rate of 6.4%. Among various emissions, the reduction of carbon emissions is the greatest. The carbon emission reduction is 2471.1 tons (accounting for 98.9% of the total emissions), with a reduction rate of 6.5%. The reduction of takeoff fuel consumption and emission by thrust adjustment is significant to aircraft energy conservation and emission reduction.

摘要： 起飞是飞行过程中一个非常重要的阶段。为研究起飞推力对油耗和排放的影响，基于多 种数据，建立一种耦合的起飞油耗计算方法，以广州白云机场起飞的B738、A320、A321、B737为 研究对象，比较不同方法的起飞油耗计算结果，分析推力对起飞油耗和排放的影响，并对比分析 推力调整后起飞排放的变化情况。结果表明：本文方法计算结果准确性较高，与真实数据相比，4 种机型起飞油耗平均相对差值分别为-2.32%、5.41%、2.31%和-3.80%；B738和B737随着推力的 增加，起飞油耗先减少后增加，推力在77%和81%时，起飞油耗最低；A320随着起飞推力越大，起 飞油耗越少；A321 随着推力越大，起飞油耗越多；采用推力调整后，广州白云机场 B738、B737、 A320、A321这4种机型的年起飞排放量累计可减少2499.3 t，减少率达6.4%；在各种排放物中，碳 排放量减少最多，为2471.1 t，占总排放物的98.9%，减少率达6.5%。采用推力调整减少起飞油耗 和排放对航空器节能减排有重要意义。
