摘要
为减小扇区空中交通飞行对环境的影响,使用高度层分配优化方法开展了基于降低温室效应的航空器绿色轨迹优化研究.首先针对扇区航空器运行的特点,结合区域扇区飞行冲突解脱方法,综合考虑扇区空中交通排放的CO_2和产生的凝结尾对全球地表温度变化的影响;其次,以最小化全球地表温度变化为目标,建立区域扇区飞行调配模型,选用高度改变冲突调配策略,并采用带精英保留策略的遗传算法求解模型;最后,使用某市02号高空管制区的实际运行数据进行了实例验证.研究结果表明:该模型能够显著降低扇区航空器运行造成的全球地表温度增加;在25、50a和100a时间水平下全球地表温度增加值分别降低了98.74%、97.69%、97.11%;飞行高度层分配优化能大幅度降低温室效应.
To reduce the regional environmental impacts of air traffic flow,this study investigated a green trajectory optimization method for reducing greenhouse effect. According to the characteristics of the regional sector aircraft and the flight conflict resolution method,the influences of CO_2 emissions and aircraft contrails on global surface temperature change were analysed and a regional aircraft deployment model was established to minimise the greenhouse effect. A genetic algorithm based on the elite retention strategy was designed. The feasibility of this algorithm was verified using real flight operations data of ZBAAAR02 as an example. The calculation result shows that the model can effectively reduce the rise in global temperature due to flight operations in the sector. The global surface temperature can decrease by 98. 74%,97. 69%,and 97. 11% in 25,50,and 100 years respectively with this model. The results obtained suggests that flight level allocation model optimisation can effectively reduce the greenhouse effect.
