A solid-fuel rocket assembly including an elongate fuel container having a long axis, and an inner surface spaced outwardly from, and generally circumsurrounding, that axis, and a continuous, elastomeric, heat-insulative, intumescence-behavior jacket adhered to the container's inner surface and defining a central chamber for receiving an elongate body of solid fuel. This structure implements a method for minimizing, in a solid-fuel rocket, heat damage to the wall of a solid-fuel container during burning of contained solid fuel including the steps of (a) producing dual-interface, continuous-presence, heat-insulative barriering in the zone existing between the container and burning fuel, with such barriering being characterized by (1) interfacially following any heat-produced deformations in the container wall, and (2) interfacially confronting the burning fuel with a tendency for intumescence-driven barrier-thickening.

We claim: 1. A solid-fuel rocket assembly comprising an elongate body of solid rocket fuel having a generally central long axis, and an outer surface spaced outwardly from, and generally circumsurrounding, said axis, an elongate fuel container having an inner surface spaced outwardly from, and generally circumsurrounding, the fuel body's said outer surface, and a continuous, seamless, elastomeric, heat-insulative, intumescence-behavior jacket adhered to said container's said inner surface and generally circumsurrounding said fuel body's said outer surface. 2. The assembly of claim 1, wherein said jacket is formed of a sprayed-in-place, high-elastomeric material including an embedded distribution of sodium silicate intumescence elements. 3. The assembly of claim 2, wherein the embedded distribution of intumescence elements is substantially uniform throughout said jacket. 4. The assembly of claim 2, wherein the embedded distribution of intumescence elements is non-uniform, in the sense of possessing a density gradient which transitions from larger-to-lesser progressing outwardly in the jacket in a direction extending through the jacket from adjacent said fuel body toward said container. 5. The assembly of claim 2, wherein said jacket further includes an embedded distribution of reinforcing fibres. 6. A solid-fuel rocket assembly comprising an elongate fuel container having a long axis, and an inner surface spaced from and generally circumsurrounding said axis, and a continuous, seamless, elastomeric, heat-insulative, intumescence-behavior jacket (a) adhered to said container's said inner surface, (b) spaced from and generally circumsurrounding said axis, and (c) defining a central chamber for receiving an elongate body of solid rocket fuel. 7. A method for minimizing, in a solid-fuel rocket, heat damage to the wall of a solid-fuel container during burning of contained solid fuel comprising placing between the container and contained fuel a structurally continuous, seamless, heat-insulative barrier having an outer surface which is adhered to the container, and an inner surface which faces the contained solid fuel, and during burning of the contained fuel, (a) utilizing surface-adherence and material elasticity in the barrier's outer surface to cause that surface to follow any heat-created deformations occurring in the adjacent container wall, and (b) simultaneously utilizing the barrier's inner surface to confront the burning solid fuel with intumescence behavior.
