以往将末制导炮弹视为由弹体以及惯导陀螺组成的两刚体系统，以分析陀螺动力学特性对弹体弹道特性的影响，而忽略弹体运动对惯导陀螺转子定向性的作用。为了确定惯导陀螺转子定向性对弹道特性产生的影响，通过计算运载体传递到内、外框架的作用力矩，得到陀螺转子进动角速度模型，对末制导炮弹惯导飞行增程段弹道进行仿真，分析得到转子在空间的运动并非具有定轴性，而是会产生一定的偏转，且陀螺转子进动对弹道特性产生一定影响的结论。

The ballistic of a model certain terminal guided projectile was built and considered as a system made up with body and inertial gyro, for analyzed the influence of precession inertial gyro on ballistic, but the dynamic of body transferred to gyro was neglected. To study directional characteristic of rotor, the moment of external frame and internal frame transferred from carrier were calculated. The simulation software for terminal guided projectile was compiled, and the numerical simulation of extended-range trajectory was carried out. The conclusions suggest that the influence gyroscopic precession on ballistic characteristics of terminal guided projectile can be ignored, it has important instructive significance to design new type of terminal guided projectile.
