摘要
Abstract
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.关键词
