火箭主动段飞行过程中,由于测控设备失效,导致测量数据丢失,设备恢复后无法快速重捕目标。利用某点测量数据的速度值,参考理论弹道上最相近速度值,引入科氏力概念,通过对变质量质点的运动力学分析,实现数据修正及弹道的外推。以MFC为软件应用平台,研究实现一种新型运载火箭飞行引导机制软件。试验表明,该新型运载火箭飞行引导机制,能够高精度、全弧段实现火箭飞行主动段的有效引导。并且基于MFC平台的软件系统具有很强的灵活性和可操作性。

In rocket’s powered flight process,since the failure of monitoring and control equipment,it causes the measured data miss and unable to fast re-capture the target after the equipment being recovered.To solve the problem,by using the speed value of measured data at certain point,referring to the most appropriate speed value in theoretical trajectory,and introducing Coriolis force concept,we realise the data revision and trajectory extrapolation through kinematics analysis on variable mass particles.Furthermore,we study and implement a novel flight guidance mechanism software for launch vehicle by taking MFC as the software application platform.Tests show that the new guidance mechanism can realise effective guidance in powered flight phase of the rocket with high precision and whole arc,the MFC platform-based software system has very good flexibility and operability.
