摘要

PURPOSE: A sealing plug for a combustor of a rocket engine is provided to prevent structural damages to a wall of a combustor caused by the sealing plug because the sealing plug is made of rubber. CONSTITUTION: A sealing plug for a combustor of a rocket engine(200) comprises a rubber tube, a pipe(203), a limiter(211), a first cap, a second cap and a pressure gauge(209). The rubber tube has a gas injection port(202) with a third cap. A check valve with a spring is attached to the pipe. The limiter is connected to the check valve by a supporter. The first and second caps seal the both ends of the pipe. The pressure gauge checks the internal pressure of the tube.
