摘要
针对大型飞机巡航段性能优化问题,文中以飞机模型和简化的飞机运动方程为基础,利用飞机的一些基本数据,首先计算出飞机的燃油里程,并在此基础上分别获得最大航程马赫数、远程巡航马赫数和经济巡航马赫数。最后建立了以巡航成本最小、燃油最省和续航时间最长为指标的优化性能数据库,并进行了仿真分析。
In order to optimize the performance of large aircraft in cruise phase,this paper firstly calculates the specific range of the aircraft based on the aircraft model and the simplified aircraft motion equation,and then obtains the maximum range Mach number,the long-range cruise Mach number and the economic cruise Mach number respectively.Finally,the optimal performance database is established with the minimum cruise cost,the least fuel and the maximum cruise time as the optimization index,and the simulation analysis is carried out.
