Abstract:

An aircraft fuselage insulation blanket of the flexible type including an insulator core (24), including a predetermined volume contained by a vented flexible blanket casing (26) having a vented plurality of seam joined tailored panels (30), in which the seams are hermetically sealed. The panels include a flexible encasement material (29), having at least direct sealing properties to form hermetic seals (33), including at least a flexible plastic barrier film (52). The casing (26) has at least one vent (34), attached to at least one hermetic joined gas flow adapter (36), to displace air and to be connected by gas flow connector (38) to a substantially inert gas pressure source (39), to inflate blanket (14). Pressure source (39) includes a modular control (37), by which the blanket can be regulated to a predetermined substantially positive pressure relative to the cabin compartment (10) atmosphere's pressure, to displace and to occlude moist air from the blanket. The modular control (37) includes a discharge outlet (40), connected by fuel tank gas connector (42) to supply substantially inert gas to at least one fuel tank's head space (23).
