Rupture disc bulkhead structure for use in a multi-stage rocket motor for missiles or the like wherein the disc is supported by a multiple apertured backup member. The disc has a series of bulges which define dimples that conform to the configuration of the apertures in the backup member. Bulging of the disc is carried out under a pressure exceeding that of the withstand pressure of the supported disc. Score lines in the disc aligned with the support segments of the apertured backup member permit the disc to rupture and open at a pressure significantly l...
