The present invention relates to a rupture disk, and more specifically to a rupture disk with formation of hollowness so that an ignition propulsion module of a rocket may be installed by penetrating through a center of the rupture disk provided between each chamber of the rocket having multi-stage propulsion chambers. For this, the present invention provides a rupture disk installed between each chamber of the rocket having multi-stage chambers, which comprises; a dome part provided with a rupture groove to control rupture pressures of the rupture disk; and a flange formed along the periphery of the dome part to be combined to an inside wall of the chamber; and hollowness formed in the center of the dome part to allow combining of an ignition propulsion module of the rocket. |
