The tangential acceleration formula has been deduced and lateral guidance law has been given when the RLV flies along the trajectory of HAC .

根据 航向 调整段轨迹的数学描述，推导出了沿此轨迹飞行的 速度 变化规律，并给出了侧向平面内的制导规律。

Considering that it is more meaningful to know the acceleration components relative to a moving trace instead of those along longitudinal lateral and normal axes of targets a time-varying nonlinear state model describing tangential and normal acceleration maneuvers of targets in three-dimensional space is established .

建立了描述目标在三维空间中进行 切 向与法向 机动的非线性状态模型。

曲线运动 中点 的 切 向和法 向 加速度的数学推导

Do not confuse ever the tangential acceleration which is along the circumference with a centripetal acceleration .

但是别把这个 切 向 加速度，它是沿着圆周的，和向心加速度混淆。
