Abstract
Abstract Sheets of metal foil superalloy heat-resisting metal foil, aluminized mylar or other thermal insulators are superposed one upon the other and deployed over the surface to be protected. A "dead space" thermal insulation such as a vacuum or simply a high resistance physical separation, is provided between surfaces. Physical separation between surfaces may be effected by flaps, integral to the insulator material, which are actuated by an aerodynamic or forced airstream or by the static energy stored in uncoiled flaps. Deployment is effected, only when needed, either by automatic or manually controlled reels which dispense the insulating material.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
60 words
An environmental protection system for protecting a spacecraft surface from a hostile environment, comprising: a. a spacecraft exterior surface to be protected; b. a layer of insulating material adapted to be rolled up in a compact roll when not in use; and, c. means for deploying said insulating material between said spacecraft surface to be protected and said hostile environment.
Claim 2
Dependent Claim
60 words
An environmental protection system for protecting a spacecraft surface from a hostile environment, comprising: a. a spacecraft exterior surface to be protected; b. a layer of insulating material adapted to be rolled up in a compact roll when not in use; and, c. means for deploying said insulating material between said spacecraft surface to be protected and said hostile environment.
Claim 3
Dependent Claim
86 words
An environmental protection system for protecting a surface from a hostile environment, comprising: a. a layer of insulating material adapted to be rolled up in a compact roll when not in use; b. deployment means for deploying said insulating material between said surface to be protected and said hostile environment; and, c. aerodynamically-operated flap separation means integral with said insulating material in such manner that said separation means is adapted to be displaced from the plane of said insulating material when said insulating material is unrolled.
Claim 4
Dependent Claim
86 words
An environmental protection system for protecting a surface from a hostile environment, comprising: a. a layer of insulating material adapted to be rolled up in a compact roll when not in use; b. deployment means for deploying said insulating material between said surface to be protected and said hostile environment; and, c. aerodynamically-operated flap separation means integral with said insulating material in such manner that said separation means is adapted to be displaced from the plane of said insulating material when said insulating material is unrolled.
Claim 5
Dependent Claim
87 words
An environmental protection system for protecting a surface from a hostile environment comprising: a. a layer of insulating material adapted to be rolled up in a compact roll when not in use; b. deployment means for deploying said insulating material between said surface to be protected and said hostile environment; and, c. prestressed, self-actuating coil separation means integral with said insulating material in such manner that said separation means is adapted to be displaced from the plane of said insulating material when said insulating material is unrolled.
Claim 6
Dependent Claim
87 words
An environmental protection system for protecting a surface from a hostile environment comprising: a. a layer of insulating material adapted to be rolled up in a compact roll when not in use; b. deployment means for deploying said insulating material between said surface to be protected and said hostile environment; and, c. prestressed, self-actuating coil separation means integral with said insulating material in such manner that said separation means is adapted to be displaced from the plane of said insulating material when said insulating material is unrolled.
Claim 7
Dependent Claim
105 words
An environmental protection system for protecting a surface from a hostile environment, comprising: a. a plurality of superposed layers of insulating material having their peripheral edges bonded together and adapted to be rolled up in a compact roll when not in use; b. deployment means for deploying said insulating material between said surface to be protected and said hostile environment; and, c. prestressed, self-actuating coil separation means integral with and disposed between said layers of insulating material in such a manner that said self-actuating coil separation means is adapted to be displaced from the plane of said insulating material when said insulating material is unrolled.
