Sustainer Forward Retention Ring

Below is a cross section and drawing of the sustainer forward retention ring. Solidworks FEA was done on both booster and sustainer retention rings.The inner part inserts into the case itself then the top part rests on the case thickness. There are holes in the top lip for screws to screw into the mission package tube.
