Abstract
Abstract In a climate controlled chamber, an insulation blanket for controlling condensation of water vapor and for channeling the condensate to a central collection point. The preferred embodiment involves an aircraft fuselage having specially constructed insulation blankets arranged in overlapping fashion in close proximity to the exterior skin of the fuselage. Each blanket has a sandwich construction comprising a centrally located corrugated metallic foil member surrounded by layers of insulating material such as fiberglass mat. The insulating materials are of predetermined thicknesses to maintain the metallic foil member with a temperature range wherein it will act as a condenser plate for water vapor. The corrugations of the foil member are vertically aligned and spaced from the insulation material on the interior side such that vertical drain passageways are formed to allow draining of the condensed water. The drain passageways turn outwardly toward the fuselage exterior skin at the lower end of each of the blankets to thereby direct the water out of the blanket and downwardly along the interior of the skin to a central collection point at the bottom of the fuselage for optional recycling through a humidifier system, or removal from the aircraft.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
206 words
An insulation blanket for use within a climate controlled chamber having cold exterior walls; said blanket having a sandwich construction comprising: a corrugated metallic foil member centrally located between an inner layer and an outer layer of insulating material and oriented such that the corrugations extend from one end to an opposite end of said blanket; said inner layer of insulating material comprising a non-wicking glass fiber mat having relatively flat sides with one side pressed against raised portions of the corrugations of said foil member to thereby cooperate with the valleys of said corrugations to form open passageways extending from one end to the opposite end of said blanket; said inner layer of insulating material being capped with a water permeable cover; each of said inner and outer layers having predetermined thicknesses to provide means to normally maintain the temperature of said metallic foil member within a range suitable for condensation of water vapors and draining of condensate out of said blanket along said open passageways and wherein said outer layer of insulating material comprises a closed cell foam adhering to the foil member, and said water permeable cover on said inner layer of insulating material includes a reflective coating for minimizing radiant heat losses.
Claim 2
Dependent Claim
206 words
An insulation blanket for use within a climate controlled chamber having cold exterior walls; said blanket having a sandwich construction comprising: a corrugated metallic foil member centrally located between an inner layer and an outer layer of insulating material and oriented such that the corrugations extend from one end to an opposite end of said blanket; said inner layer of insulating material comprising a non-wicking glass fiber mat having relatively flat sides with one side pressed against raised portions of the corrugations of said foil member to thereby cooperate with the valleys of said corrugations to form open passageways extending from one end to the opposite end of said blanket; said inner layer of insulating material being capped with a water permeable cover; each of said inner and outer layers having predetermined thicknesses to provide means to normally maintain the temperature of said metallic foil member within a range suitable for condensation of water vapors and draining of condensate out of said blanket along said open passageways and wherein said outer layer of insulating material comprises a closed cell foam adhering to the foil member, and said water permeable cover on said inner layer of insulating material includes a reflective coating for minimizing radiant heat losses.
Claim 3
Dependent Claim
31 words
The blanket of claim 1 which includes means for maintaining the temperature of the foil member above the freezing point of water comprising resistance heating elements connected to the foil members.
Claim 4
Dependent Claim
241 words
An insulation blanket for use within a climate controlled chamber having cold exterior walls; said blanket having a sandwich construction comprising: a corrugated metallic foil member centrally located between an inner layer and an outer layer of insulating material and oriented such that the corrugations extenD from one end to an opposite end of said blanket; said inner layer of insulating material comprising a non-wicking glass fiber mat having relatively flat sides with one side pressed a raised portions of the corrugations of said foil member to thereby cooperate with the valleys of said corrugations to form open passageways extending from one end to the opposite end of said blanket; said inner layer of insulating material being capped with a water permeable cover; each of said inner and outer layers having predetermined thicknesses to provide means to normally maintain the temperature of said metallic foil member within a range suitable for condensation of water vapors and draining of condensate out of said blanket along said open passageways, and wherein said outer layer of insulating material comprises an non-wicking glass fiber mat having one side pressed against raised portions of said corrugated metallic foil member, and wherein at one end of said blanket, said foil member is bent outwardly such that said open passageways will direct condensed moisture away from a next adjoining blanket if said blanket is used with other such blankets in an overlapping fashion within a climate controlled chamber.
Claim 5
Dependent Claim
241 words
An insulation blanket for use within a climate controlled chamber having cold exterior walls; said blanket having a sandwich construction comprising: a corrugated metallic foil member centrally located between an inner layer and an outer layer of insulating material and oriented such that the corrugations extenD from one end to an opposite end of said blanket; said inner layer of insulating material comprising a non-wicking glass fiber mat having relatively flat sides with one side pressed a raised portions of the corrugations of said foil member to thereby cooperate with the valleys of said corrugations to form open passageways extending from one end to the opposite end of said blanket; said inner layer of insulating material being capped with a water permeable cover; each of said inner and outer layers having predetermined thicknesses to provide means to normally maintain the temperature of said metallic foil member within a range suitable for condensation of water vapors and draining of condensate out of said blanket along said open passageways, and wherein said outer layer of insulating material comprises an non-wicking glass fiber mat having one side pressed against raised portions of said corrugated metallic foil member, and wherein at one end of said blanket, said foil member is bent outwardly such that said open passageways will direct condensed moisture away from a next adjoining blanket if said blanket is used with other such blankets in an overlapping fashion within a climate controlled chamber.
Claim 6
Dependent Claim
26 words
The blanket of claim 3 wherein said water permeable cover on said inner layer of insulating material includes a reflective coating for minimizing radiant heat losses.
