Inhibitor and thermal insulation liner for propellant grains

Claim 1

THE METHOD OF PRODUCING AN INHIBITOR AND THERMAL INSULATION LINER FOR RESTRICTING THE BURNING SURFACE OF A SOLID PROPELLANT GRAIN WITHIN A SOLID PROPELLANT ROCKET COMBUSTION CHAMBER AND FOR WITHSTANDING TEMPERATURES IN EXCESS OF 3000*F. WHILE RETAINING ITS SOLID CONDITION, COMPRISING THE STEPS OF: FORMING AN INHIBITOR AND THERMAL INSULATION LINER OF SHRINKABLE PLASTIC COMPOSITION INTO AN ORIGINAL SHAPE HAVING PREDETERMINED DIMENSIONS; IRRADIATING THE PLASTIC LINER TO PRODUCE A DIMENSIONAL MEMORY EFFECT TO THE MOLECULES OF PLASTIC CONFORMING TO THE ORIGINAL PREDETERMINED DIMENSIONS; HEATING THE PLASTIC LINER ABOVE ITS CRYSTALLINE MELTING TEMPERATURE SO THAT IT IS FLEXIBLE; DEFORMING THE PLASTIC LINER IN ITS FLEXIBLE CONDITION INTO A MODIFIED SHAPE HAVING GREATER DIMENSIONS THAN THOSE EXHIBITED BY THE ORIGINAL SHAPED LINER; COOLING THE DEFORMED PLASTIC LINER BELOW ITS CRYSTALLINE MELTING TEMPERATURE TO LOCK THE MOLECULES INTO THE MODIFIED CONDITION; ASSEMBLING SAID DEFORMED PLATIC LINER AROUND THE PROPELLANT GRAIN WHICH HAS DIMENSION RANGING BETWEEN THOSE EXHIBITED BY THE ORIGINAL SHAPE OF THE LINER AND THOSE EXHIBITED BY THE DEFORMED SHAPE OF THE LINER; AND REHEATING THE PLASTIC LINER ABOVE ITS CRYSTALLINE MELTING

Claim 2

THE METHOD OF PRODUCING AN INHIBITOR AND THERMAL INSULATION LINER FOR RESTRICTING THE BURNING SURFACE OF A SOLID PROPELLANT GRAIN WITHIN A SOLID PROPELLANT ROCKET COMBUSTION CHAMBER AND FOR WITHSTANDING TEMPERATURES IN EXCESS OF 3000*F. WHILE RETAINING ITS SOLID CONDITION, COMPRISING THE STEPS OF: FORMING AN INHIBITOR AND THERMAL INSULATION LINER OF SHRINKABLE PLASTIC COMPOSITION INTO AN ORIGINAL SHAPE HAVING PREDETERMINED DIMENSIONS; IRRADIATING THE PLASTIC LINER TO PRODUCE A DIMENSIONAL MEMORY EFFECT TO THE MOLECULES OF PLASTIC CONFORMING TO THE ORIGINAL PREDETERMINED DIMENSIONS; HEATING THE PLASTIC LINER ABOVE ITS CRYSTALLINE MELTING TEMPERATURE SO THAT IT IS FLEXIBLE; DEFORMING THE PLASTIC LINER IN ITS FLEXIBLE CONDITION INTO A MODIFIED SHAPE HAVING GREATER DIMENSIONS THAN THOSE EXHIBITED BY THE ORIGINAL SHAPED LINER; COOLING THE DEFORMED PLASTIC LINER BELOW ITS CRYSTALLINE MELTING TEMPERATURE TO LOCK THE MOLECULES INTO THE MODIFIED CONDITION; ASSEMBLING SAID DEFORMED PLATIC LINER AROUND THE PROPELLANT GRAIN WHICH HAS DIMENSION RANGING BETWEEN THOSE EXHIBITED BY THE ORIGINAL SHAPE OF THE LINER AND THOSE EXHIBITED BY THE DEFORMED SHAPE OF THE LINER; AND REHEATING THE PLASTIC LINER ABOVE ITS CRYSTALLINE MELTING
