Evaluating the Severity of Rocket Motor Case during Burst Test Using Acoustic Emission

Source

The method of evaluating the severity of flaws by acoutic emission techniques was applied to the burst test of rocket motor case, in order to evaluate the structural integrity of the motor case during hydraulic pressurization. Three regions of high activity in acoustic emission signals were observed, and two of these became an initial point of fracture. The evaluation method used in the present test could anticipate these fracture characteristics very well before rupture.
