This paper researches into reentry vehicle impact errors which result from the rollvelocity changes by use of rotor dynamic theory.

But just having the bird in its cradle resulted in the ambulating carrier bot running with more stability, reducing the variance in pitch and rollvelocity by as much as 90 percent.
但是,仅仅有在摇篮鸟导致走动载体机器人更稳定的运行,高达90%降低俯仰和滚转速度的变化。

When we have pure roll, the velocity of this point Q, and the velocity of the circumference, - if you can read that — are the same.
