基于飞机性能的连续爬升程序建模和油耗分析

Performance based continuous climb operation modeling and fuel consumption analysis

随着航线数量的不断增长和机场进离场交通的日渐繁忙,因管制压力造成的离场阶段改平飞行导致了飞机非必需的燃油消耗,为航空公司带来经济效益上的损失。为了减少平飞并实现快速离场,基于性能的导航(PBN)模式下的连续爬升运行(CCO)成为解决该问题的方式。介绍了BADA飞机性能模型的构建方法,并使用性能模型对CCO进行设计,并提出了前后CCO离场可能产生的冲突和解脱方法,结合实际航线对爬升时间和油耗进行了仿真分析,结果显示CCO离场能够缩短爬升时间,减少燃油消耗;在冲突发生时通过速度调整可以比阶梯爬升的方式更有效益。

With the increase of arrival and departure traffic at the airport, the leveling in the departure stage caused by traffic control limits have caused unnecessary fuel consumption for aircrafts and brought economic losses to airlines. In order to reduce level flight and achieve rapid departure, the continuous climb operation(CCO) based on performance-based navigation(PBN) mode has became a way to solve this problem. The construction method of the BADA aircraft performance model is introduced, the CCO is designed using the performance model, and a conflict resolution method is proposed. The climb time and fuel consumption are calculated according to an actual flight profile. The simulation results show that CCO departure can shorten the climb time and reduce fuel consumption, and the adjustment of speed is better than using step climb when a conflict happens.
