Abstract
A device for the impervious sealing of a structure, for example a munitions compartment of a rocket, is disclosed. This device comprises an elastic shaped section inside which the edge of the structure and rim of a lid are imperviously embedded. This device further has means for thrusting the lid outwards from the structure. This thrust pushes the rim and/or the edge out of the shaped section through the deformation of this elastic shaped section, and causes the total expulsion of lid. When the device is fitted into a rocket, the moving away of the rim modifies the aerodynamic drag coefficient (Cx) of the rocket. This difference in Cx causes the total expulsion of the lid and thus causes the structure to be opened.
