Stabilization of a Liquid-Filled Shell by Inserting a Cylindrical Partition in the Liquid Cavity
Abstract
In July 1968, the SM613, a 107mm, WP mortar shell, was range tested at Yuma Proving Ground. The projectile had a history of flight instabilities when the WP was in the liquid state. Specifically modified rounds incorporating a cylindrical partition mounted concentrically to the central burster experienced stable flights. The rationale of inserting cylindrical partitions in liquid filled shell is explained as being a straightforward and flexible method of changing internal geometries to produce stable flight by means of understood design procedures.
