Solid Rocket Motor (SRM) is designed with very few moving parts for consistent performance and longer shelf life, making it an attractive choice for missiles, heavy-lift applications, and boosters for satellite launchers. This paper discusses the Solid Rocket Motor configuration and its processing, in brief. During its processing and operation, SRMs experience thermal stress at various stages, which, if left unrelieved, become detrimental to the operation of SRM. This paper presents the details of thermal stress relievers in the internal insulation of metallic case SRMs and composite case SRMs. Also, the challenges faced during the processing of SRMs with thermal stress relievers and the improvements incorporated to overcome them, which were successfully tested in flights, are discussed in detail.
