<P>PROBLEM TO BE SOLVED: To accomplish, with a simple configuration, a combustion gas supply control device which supplies combustion gas to a predetermined combustion gas exhaust hole at a desired timing in an unseparated thruster type multi-pulse rocket motor or the like. <P>SOLUTION: A combustion gas generator has: a motor case; a first propellant loaded within the motor case to combust at a first pulse; a second propellant loaded within the motor case to combust at a second pulse subsequent to the first pulse; a front motor head fixed to a front portion of the motor case and having a combustion gas exhaust hole; and a back end plate fixed to a rear portion of the motor case and having a combustion gas exhaust hole. A combustion gas supply control device prevents combustion gas of the first propellant at the first pulse from flowing into the combustion gas exhaust hole of the front motor head and supplies combustion gas of the second propellant at the second pulse to the combustion gas exhaust hole of the front motor head. <P>COPYRIGHT: (C)2013,JPO&INPIT |
