摘要
介绍了潜射弹道导弹水下发射技术研究过程中的一些特点,假设了一种水下弹射模型弹运动参数的捷联式测量方法,导出了考虑发射潜艇6自由度运动条件下模型弹的初始运动条件,给出了弹体转动运动微分方程的方向余弦形式、四元数形式的解析解,推导了根据测量参数求模型弹的姿态角、质心坐标和速度的算法。
Characteristics of underwater launching of submarine-launched ballistic missile are introduced. A strapdown inertial measurement method for motion parameters of a underwater-ejected model missile is proposed and the initial motion condition of model missile available while the submarine is in 6-DOF movement is given. Then, analytical solutions of quaternion and orientation cosine for body movement differential equation are given. Finally, algorithm for attitude angle, center-of-mass coordinates and velocity based on measurement parameters are deduced.
