<p><P>PROBLEM TO BE SOLVED: To provide a pulse rocket motor capable of reliably performing a second pulse by reliably preventing the intrusion of a flame into a second propellant at a first pulse by a simple configuration. <P>SOLUTION: A diaphragm member 10 for covering the second propellant 8 includes a diaphragm 24 which extends along a rear end surface from an inner peripheral surface of the second propellant 8 and metallic diaphragm holders 26a and 26b which are integrated by vulcanized adhesion at both ends of the diaphragm 24 and which are attached to a pressure vessel. A protrusion 30a, which has a protrusive cross section and in which a part vulcanization-adhering to the diaphragm 24 extends backward at least over a range of a propellant support 22, is formed on the diaphragm holder 26a on a front end side. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
