摘要
针对飞翼类飞行器迫降轨迹设计问题,建立力学运动模型对无动力滑翔过程进行分析,采用满足始末端约束和飞行器性能约束的Dubins轨迹进行轨迹搜索,并提出根据迫降初始能量状态采用广义Dubins类型航线规划低能迫降轨迹和高能迫降轨迹。通过批量仿真验证了迫降飞行阶段分段管理和能量实时评估实现迫降轨迹设计的方法使飞行器精确回收到迫降点的同时兼具适应环境干扰的鲁棒性,对实际工程应用具有重要意义。
Aiming at the problem of forced landing trajectory design of flying wing aireraft,a mechanical motion model is established to analyze the unpowered gliding process,the Dubins trajectory meet ing the initial terminal constraints and aircraft performance constraints is used for trajectory design,and a generalized Dubins type route is proposed to plan the low-energy and high-energy forced landing trajectory according to the initial energy state of forced landing.Through batch simulation,it is verified that the method of realizing the design of the forced landing trajectory by segment management and real-time energy evaluation in the forced landing flight stage not only accurately recovers the aireraft to forced landing point,but also has the robustness to adapt to environmental interference,which is of great si gnificance to practical engineering application.
