| Abstract: |
| This paper reveals an improved test method for thermal matching failure mode of free-standing solid rocket motor.Through adding differential pressure sensor, the influence of traditional test method on measurement accuracy is effectively reduced.Thus, the existence of the pressure difference between the inner and outer sheath of the engine is confirmed, which strongly supports the research results of thermal matching failure mode mechanism. |
