摘要
航空兵任务规划系统中飞机空对地攻击航线解算的准确性、航线生成质量和航线解算速度是衡量任务规划系统能力的重要指标。飞机空对地攻击航线设计是飞机航线规划中典型的多约束复杂机动,其在设计与使用过程中受到来自时间、空间及飞机本体的多维约束,对飞行动力学建模与航迹优化提出了较高的要求。本文利用面向对象的思想对飞机无侧滑动力学模型进行建模,通过航线机动动作拼接、分段优化的方式实现复杂机动过程的设计与优化,并进行仿真分析。结果表明:该航线优化设计能够实现飞机多约束航迹设计与规划功能,迭代优化算法具有较好的收敛性,可满足航空兵任务规划使用要求。
In aviation mission planning system,the accuracy of aircraft air-to-ground attack route solution,route generation quality and route calculation speed are important indicators to measure multi constraint complex maneu⁃ver in aircraft route planning.In the process of design and use,it is subject to multi-dimensional constraints from time,space and aircraft body,which puts forward high requirements for flight dynamics modeling and track optimi⁃zation.In this paper the object-oriented thinking is used to model the aircraft's side-slip dynamics model,and the design and optimization of the complex maneuvering process are realized by the way of route maneuvering splicing and segmental optimization.After simulation analysis,it is proved that the route optimization design can realize the multi-constrained trajectory design and planning function of the aircraft in terms of ideas and methods.The iterative optimization algorithm has good convergence,and the model and algorithm can meet the requirements of aviation mission planning.
