Design and Analysis of Solid Rocket Motor Internal Insulation,
EUROPEAN SPACE AGENCY PARIS (FRANCE)
Pagination or Media Count:
The main purpose of internal insulation is to protect the motor case from the thermal environment of propellant combustion products. Several secondary objectives must also be met. Internal insulation must bond to propellant and case, transmit case strain into propellant and sometimes seal the case. In the first step, the general process of internal insulation design is presented evaluation of thermal environment, selection of material, thermal and structural analyses. For each phase the different analysis methods are described aerodynamic, thermal, and structural. The different phases of internal insulation fabrication are also presented elastomer formulation, fabrication of parts and integration into the motor case.
