Abstract:

When the XM687 liquid-filled projectile is launched with small yaw a smooth spin record is obtained which can be accurately predicted by theories based on the Wedemeyer spin-up model. A few rounds with large first maximum yaw have a different type of spin record exhibiting a rapid initial spin decay, followed by a corner, or discontinuity in slope.
