An insulation baffle for a mobile platform. The baffle is secured to a structure
separating different lobes of the mobile platform. The baffle includes a main body
portion and at least one blow out portion. A perimeter of the blow out portion
is defined by at least one recess. The recess also forms a web portion that connects
the blow out portion with the main body portion. A depth of the recess is predetermined
such that the web portion formed by the recess will sever when a pressure differential
between the different lobes exceeds a predetermined threshold. When the web portion
severs at least a section of the blow out portion separates from the main body
portion to air to pass between the lobes so that the pressure differential is reduced
to approximately zero.
