Static test for motor rocket RX-250 was conducted at Static Test Laboratory of LAPAN Rumpin in order to measure the amount of thrust measured by the motor rocket. During the test, it was observed that the motor rocket cylinder failed at internal pressure of 120 atmosphere at the fourth second of supposed six-second-long burning time. While according to the theoretical analysis result, the maximum allowable internal pressure for this motor rocket tube was 130 atmosphere. The motor rocket tube was 2 m long with wall thickness of 1 cm and cap thickness of 1.1 cm. This paper analysis the cause of motor rocket tube failure. The analysis is emphasised on the effect of excessive thermal stress on one area due to imperfection of propellant connection such that the ignition fire has reached the wall of the motor rocket earlier than expected. The thermal analysis used the result from previous research on the material properties of a! alloy used in the current motor rocket at different temperatures.
