This report examines the control authority of an 81-mm mortar projectile equipped with an internal translating mass. The translating mass undergoes controlled motion within the projectile body, resulting in a lateral mass center offset that creates a drag-induced moment. This moment can be utilized to guide the round to a target. Several example studies demonstrate basic control authority characteristics, while trade studies examine the effect of projectile static stability as well as mass size, oscillation amplitude, and location on overall maneuver capability.
