A cigarette includes lighting and mouth ends. It also includes a mouth-end segment; an aerosol-generation system disposed between the lighting and mouth ends, which includes (i) a heat-generation segment adjacent the smokable segment, including a heat source configured to be activated by combustion
A cigarette includes lighting and mouth ends. It also includes a mouth-end segment; an aerosol-generation system disposed between the lighting and mouth ends, which includes (i) a heat-generation segment adjacent the smokable segment, including a heat source configured to be activated by combustion of a smokable material and an insulation layer of a non-glass material that is woven, knit, or both, shaped to retain (e.g., by interlocking engagement with) the heat source, and (ii) an aerosol-generating segment with aerosol-forming material disposed between, but physically separate from, each of the heat generation segment and the mouth end; a piece of outer wrapping material that provides an overwrap around at least a portion of the aerosol-generating segment, the heat-generation segment, and at least a portion of the smokable segment; those segments being connected together by the overwrap to provide a cigarette rod; that is connected to the cigarette rod using tipping material.

1. A cigarette comprising: a lighting end and a mouth end;a mouth end piece segment disposed at the mouth end;an aerosol-generation system disposed between the lighting end and the mouth end piece segment, the aerosol-generation system including (i) a heat generation segment disposed at the lighting
1. A cigarette comprising: a lighting end and a mouth end;a mouth end piece segment disposed at the mouth end;an aerosol-generation system disposed between the lighting end and the mouth end piece segment, the aerosol-generation system including (i) a heat generation segment disposed at the lighting end, said heat generation segment having a length and including a heat source and an insulation layer of flame-retardant material, the insulation layer configured with an inward-facing geometry configured to complementarily engage and longitudinally retain the heat source within the heat generation segment, where the insulation layer inward-facing geometry comprises a generally frustoconical space fitted securely with a generally frustoconical heat source, where an outward-facing geometry of the heat source includes at least one generally elongate channel configured to facilitate airflow; and(ii) an aerosol-generating segment incorporating aerosol-forming material, said aerosol-generating segment having a length and being disposed between, but physically separate from, each of the heat generation segment and the mouth end;a piece of outer wrapping material oriented to provide an overwrap (i) around the aerosol-generating segment for at least a portion of its length, and (ii) around the heat generation segment for the length of that segment; those segments being connected together by the overwrap to provide a cigarette rod; andthe mouth end piece segment being connected to the cigarette rod using tipping material. 2. The cigarette of claim 1, wherein the insulation layer further comprises c-glass fiber. 3. The cigarette of claim 2, wherein the c-glass fiber comprises about 20 percent, by weight, of the insulation layer. 4. The cigarette of claim 1, wherein the heat generation segment and the aerosol-generating segment are in a heat exchange relationship with one another and the insulation provides an insulative layer about at least a portion of the heat source. 5. The cigarette of claim 1, wherein the insulation layer further comprises a carbon fiber material. 6. The cigarette of claim 5, wherein the carbon fiber material comprises about 20 percent, by weight, of the insulation layer. 7.

The cigarette of claim 1, wherein the heat source outward-facing geometry comprises at least one of a plurality of exterior channels and at least one longitudinal central aperture extending along at least most of its length, each configured to facilitate airflow. 11. The cigarette of claim 1, wherein the outward-facing geometry of the heat source comprises a plurality of exterior grooves, and the inward-facing geometry of the insulation layer comprises at least one protrusion engaged with at least one of the plurality of exterior grooves. 12. A cigarette comprising: a lighting end and a mouth end;a mouth end piece segment disposed at the mouth end;an aerosol-generation system disposed between the lighting end and the mouth end piece segment, the aerosol-generation system including (i) a heat generation segment disposed at the lighting end, said heat generation segment having a length and including a heat source and an insulation layer of flame-retardant material, the insulation layer configured with an inward-facing geometry configured to complementarily engage and longitudinally retain the heat source within the heat generation segment, where an outward-facing geometry of the heat source includes at least one generally elongate channel configured to facilitate airflow; and(ii) an aerosol-generating segment incorporating aerosol-forming material, said aerosol-generating segment having a length and being disposed between, but physically separate from, each of the heat generation segment and the mouth end;a piece of outer wrapping material oriented to provide an overwrap (i) around the aerosol-generating segment for at least a portion of its length, and (ii) around the heat generation segment for the length of that segment; those segments being connected together by the overwrap to provide a cigarette rod; andthe mouth end piece segment being connected to the cigarette rod using tipping material, wherein the outward-facing geometry of the heat source comprises one of a flared tongue and a flared groove, and the inward-facing geometry of the insulation comprises the other of a flared tongue and a flared groove configured to fit complementarily together to longitudinally retain the heat source. 13. The cigarette of claim 12, wherein the heat source includes a flared region opposite the lighting end, and the insulation is configured to engage the flared region in a manner configured to longitudinally retain the heat source. 14. The cigarette of claim 12, wherein the heat source includes a decreased-diameter cylindrical segment region at the lighting end, and the insulation is configured to engage the decreased-diameter cylindrical segment region in a manner configured to longitudinally retain the heat source. 15. The cigarette of claim 12, wherein the insulation layer further comprises c-glass fiber. 16. The cigarette of claim 15, wherein the c-glass fiber comprises about 20 percent, by weight, of the insulation layer. 17. The cigarette of claim 12, wherein the heat generation segment and the aerosol-generating segment are in a heat exchange relationship with one another and the insulation provides an insulative layer about at least a portion of the heat source. 18. The cigarette of claim 12, wherein the insulation layer further comprises a carbon fiber material. 19. The cigarette of claim 18, wherein the carbon fiber material comprises about 20 percent, by weight, of the insulation layer. 20. The cigarette of claim 19, wherein the carbon fibers include at least 95% carbon. 21. The cigarette of claim 12, further comprising a buffer between the heat generation segment and the aerosol-generating segment. 22. The cigarette of claim 12, wherein the insulation layer inward-facing geometry comprises a generally frustoconical space fitted securely with a generally frustoconical heat source. 23.
