Abstract
A two-stage release self-righting mechanism and method employ a pair of primary and secondary releasable holder assemblies which respective hold upper and middle portions of leaf spring arms in a stowed position against the side wall of a load such as a submunition launcher tube. The primary holder assembly is released first which permits release of a portion of the energy stored by the spring legs, causing them to partially extend from the stowed position to a partially deployed position and partially erect the submunition. Then, a short time later, the secondary holder assembly is released, permitting release of the remaining energy stored by the spring legs, causing them to fully extend to a fully deployed position and complete the erecting of the submunition.
