Abstract: In the scope of the lightweight motor case development study, design, analysis, prototype production and verification phases of a 1 mm aluminum-lined, carbon fiber overwrapped rocket motor case presented. The development phase is completed by performing hydrostatic burst tests for six hybrid motor cases. All prototypes were conditioned to three different temperatures such as -35 °C, 23 °C and 70 °C. At the end of the test series, it was shown that all the prototypes satisfy mechanical/structural performance requirements. Hence, the motor with composite case development and verification studies were proved to be successful and in good agreement with the analysis results. The overwrapped motor cases are as much as 30 % more weight efficient than bare aluminum motor case.
