A particularly investigation is carried out to the observibility of in-flight alignment using numerical simulation when the aircraft performs four kinds of basic maneuvre, namely linear acceleration, yawing, pitching and rolling. The thesis summarizes the two kinds of maneuvre. Simulation results show that the precision of transform alignment reach 5 minutes in 10 seconds if the aircraft performs two well-defined maneuvres.

首先本文采用数值分析的方法研究了直线运动、航向角运动、俯仰角运动和横滚角运动对传递对准系统可观性的影响规律；再结合飞机的实际运动，给出了空空导弹传递对准时的飞机飞行轨迹；"蛇形"飞行轨迹和摇摆运动飞行轨迹，仿真结果表明：按这两条飞行轨迹机动，在10s内传递对准精度可达到5′以下。

So, a roll gyro in an aircraft in a coordinated turn with a 60 degree bank will be measure a rate of zero, same as an aircraft flying straight and level.

因此，在60度横滚角的飞机上的陀螺仪测得的横滚角速率值为零，同样在飞机做水平直线飞行时，角速率值为零。

If a gyro is used to measure the rate of rotation around the aircraft roll axis, it will measure a non-zero value as long as the aircraft is rolling, but measure zero if the roll stops.

使用陀螺仪测量飞机机体轴向的旋转角速率时，如果飞机在旋转，测得的值为非零值，飞机不旋转时，测量的值为零。

Module is the soul of SSPD, the basic unit of aircraft configuration control, and the foundation of aircraft MIM technology.

模块是SSPD结构的灵魂，是飞机构型控制的基本单元，是飞机制造信息管理技术实现的基础。
