An analysis was made of the thermally induced stresses in a bare and coated alumina radome. The study indicated that it would be structurally feasible to protect a radome on an advanced interceptor against thermal shock by using an ablative covering. Materials were tested to determine the effect of materi¬al thermal conductivity upon heat input rated to a ceramic radome. The alumina radome purchased from Coor's Porcelain Company of Golden, Colorado, was coated with a silicon carbide filled phenol silane impregnated graphite cloth and tested in a ramjet exhaust. This study also indicated that an ablative covering could be designed that would completely ablate within a required period to allow radar systems to function properly.
