The invention discloses a boosting separation method considering unpowered flight section speed constraint. The boosting separation method comprises the steps that S1, the moment when an engine stops working is recorded as the earliest separation time tp0; s2, the latest separation time tpmax is determined, wherein tpmax is the latest time when the control system can control the aircraft to reach the target position according to the required speed and height; s3, obtaining an altitude-speed curve of the ideal trajectory as an ideal speed curve, and recording the ideal speed curve as an H-V curve; and S4, in the actual flight process, determining the separation time of the aircraft according to the H-V curve. According to the separation method provided by the invention, the speed at the moment when the aircraft is separated from the boosting stage is limited, a proper initial speed is provided for an unpowered flight section of the aircraft, and the separation method is simple, efficient and easy to implement.

    本发明公开了一种考虑无动力飞行段速度约束的助推分离方法,包括S1将发动机结束工作的时刻记为最早分离时间tp0;S2确定最晚分离时间tp_max,tp_max为控制系统能够控制飞行器按照要求的速度和高度到达目标位置的最晚时间;S3获得理想弹道的海拔‑速度曲线作为理想速度曲线,将理想速度曲线记为H‑V曲线;S4实际飞行过程中,根据H‑V曲线确定飞行器的分离时刻。本发明提出的分离方法对飞行器与助推级分离时刻的速度进行限制,为飞行器无动力飞行段提供了合适的初速度,该分离方法简洁高效,易于实现。
