Abstract
The two-piece end cap assembly has an end cap that has a groove around its perimeter and at least one cavity. The end cap is fixed in place inside the flare case with the cavities exposed. Sealant/adhesive is applied to the groove and cavity. A RAM cap, having a flange on its edge corresponding to the size of the flare case and a number of projections corresponding to the cavities, is installed on the top surface of the end cap. The sealant/adhesive in the cavities attaches the RAM cap to the end cap. The sealant/adhesive in the groove is forced to the edges of the end cap and provides a seal between the end cap and the flare case. Radar Absorbing Material is applied to the top and exposed edges of the RAM cap, completely masking the face of the flare and its edges.
