亚轨道飞行器(SRLV)通过跟踪特定的轨迹来实现对能量的控制与管理,轨迹设计是能量管理的一项关键技术。深入研究了亚轨道飞行器能量管理段(TAEM)轨迹的设计思想、准则和流程;提出了一种基于待飞距离规划动压剖面的轨迹设计方法,通过调整航向调整段的动压剖面,保证飞行器以亚声速状态进入航向调整段,避免飞行器转弯超调;提出了采用顺风作为轨迹设计的缺省状态,保证飞行器在严重的逆风状态下仍然可以满足着陆窗口约束;通过具体算例进行仿真分析,验证了设计方法的有效性。
Sub-orbital aircraft (SRLV) by controlling the trajectory to achieve a specific energy control and management, trajectory design is a key energy management technology. In-depth study of the trajectory of the sub-orbital aircraft energy management section (TAEM) trajectory design ideas, guidelines and processes; A trajectory design method based on the dynamic range of the trajectory adjustment section to ensure that the aircraft It is assumed that the downwind is the default state of trajectory design and that the aircraft can still meet the landing window constraint under severe headwind condition. The simulation analysis is carried out through concrete examples, Verify the effectiveness of the design method.
