Very low power actuation devices

Abstract

A munition including: a control surface actuation device including: an actuator having two or more pistons, each of the pistons being movable between an extended and retracted position, the retracted position resulting from an activation of each of the two or more pistons; and a movable rack having a pocket corresponding to each of the two or more pistons, each pocket being engageable with a corresponding portion of each of the two or more pistons, a distance between the pockets being different than a distance between the portions of the two or more pistons, such that activation of the portion into the corresponding pocket sequentially translates the rack; and a control surface operatively connected to the rack such that translation of the rack rotates the control surface.
