Abstract

L'invention concerne la protection de moteurs-fusées à propergol solide. On améliore beaucoup la liaison de collage de grains de propergol à base de polybutadiène terminé par des groupes hydroxyles aux chemises de moteurs-fusées, et de la chemise à l'enveloppe du moteur, en incorporant une aziridine à une composition de formation d'une chemise à base de polybutadiène terminé par des groupes hydroxyles et durci. Mieux collee ainsi, la chemise peut mieux jouer ses rôles d'élément de liaison et d'isolant de protection de l'enveloppe des moteurs-fusées.The invention relates to the protection of solid propellant rocket motors. The sizing bond of hydroxyl-terminated polybutadiene-based propellant grains to rocket engine jackets, and from the liner to the engine jacket, is greatly improved by incorporating an aziridine into a compound forming composition. Polybutadiene-based shirt terminated with hydroxyl groups and cured. Better glued in this way, the sleeve can better play its roles as a connecting element and as a protective insulator for the rocket motor casing.
