Abstract
A method and an apparatus are devised to install an insulation rubber loop in the aft end of a rocket motor case. The method includes the making of a rubber strip into a rubber loop by casting. The rubber loop is partially cured and is then adhered to the inner wall of the aft end of the rocket motor case by using a silicone rubber loop of the apparatus. The silicone rubber loop is caused to deform so as to press against the insulation rubber loop, which is thus securely attached to the inner wall of the aft end of the rocket motor case. The attachment of the rubber loop is further enhanced by heating the rocket motor case to provide heat which is intended to facilitate the curing of the rubber loop.
