Abstract
Due to its complex design and operation in extreme conditions, the rocket motor is one of the most rated items in educational competitions and that most needs attention from the teams. Aiming to analyze the reliability of the high-power experimental solid rocket motor, from the competition team Kosmos Foguetemodelismo at the Joinville’s Technological Center of the Universidade Federal de Santa Catarina, the present work sought to list the failure modes, critical components and raise mitigation recommendations for these components. This was accomplished through the Failure Mode and Effect Analysis (FMEA). Thirteen failure modes were identified, eleven causal chains with unacceptable evaluation, twenty-one with undesirable evaluation, fourteen with acceptable if revised and five with acceptable evaluation. The critical components being the grain, the bulkhead screws and the nozzle screws.
