Abstract
An enclosure for protecting a heat sensitive item from high temperatures and shock which includes: (a) an outer housing including an inner cavity for containing at least one heat sensitive item; (b) a thermal insulator located within the inner cavity defining at least a portion of a second interior cavity, with the at least one heat sensitive item being located within the second interior cavity; and (c) a boiler located within the second interior cavity including at least one containment compartment for containing a thermal mass and at least one protective compartment within which the at least one heat sensitive item is located. The invention finds particular utility in the Flight Recorder field where heat sensitive components, such as solid state memories, may be subject to fire and shock often resulting from an aircraft crash. The invention also features a corrosion protection capability which is effective when the item being protected is in close proximity to a source of moisture. Further aspects of the invention are directed to processes for fabricating enclosures of then type contemplated by the invention (a Flight Crash Survival Storage Unit (FCSSU) in the Flight Recorder context), and to a boiler per se for use in a FCSSU of the type contemplated by the invention.
