An aerosol delivery article includes a longitudinally segmented combustible fuel element, and a substrate carrying flavor or a drug positioned physically separate from the fuel element. The fuel element is composed of a carbonaceous material and is extruded in such a manner that when positioned within the article, its extrusion axis is perpendicular to the longitudinal axis of the article. The fuel element is segmented longitudinally and includes a burning segment at one end, a base segment at the opposite end, and an isolation segment between the burning and base segments. A metal cartridge is radially spaced from the longitudinal outer periphery of the burning segment of the fuel element. A retaining member grasps the base segment of the fuel element and holds the fuel element securely in place within the article. |

DETAILED DESCRIPTION The present invention relates to aerosol delivery articles which include a fuel element (i.
e.
, a heat source) positioned in a heat exchange relationship with a physically separate aerosol generating means.
In a highly preferred aerosol delivery article, the composition and configuration of the fuel element, as well as the positioning of the fuel element within the article, are such that very efficient use is made of the heat generated by that fuel element.
As such, in a preferred article, a high proportion of the heat produced by a burning fuel element is exchanged to the aerosol generating means for aerosol generation.
In one aspect, a preferred aerosol delivery article of the present invention includes (i) an extruded combustible fuel element or heat source positioned within the article such that the extrusion axis of the fuel element is substantially perpendicular to the longitudinal axis of the aerosol delivery article; (ii) a physically separate aerosol generating means including at least one aerosol forming material; and (iii) means for securing, maintaining or retaining the fuel element within the article.
In another aspect, a preferred aerosol delivery article of the present invention includes (i) a longitudinally segmented combustible fuel element; (ii) a physically separate aerosol generating means including at least one aerosol forming material; (iii) means for securing, maintaining or retaining the fuel element within the article; and (iv) means for enclosing at least a portion of the longitudinal periphery of the fuel element so as to limit the amount of atmospheric oxygen which contacts the fuel element when the fuel element burns during use (i.
e.
, an enclosure member).
Typically, the enclosure member is capable of transferring heat from the burning fuel element to the aerosol generating means.
The aerosol delivery article includes a short, preferably carbonaceous, combustible fuel element or heat source.
Typically, the fuel element is of a longitudinally segmented design such that only a portion of the length thereof is available for burning, and a portion of the length thereof serves as a base which allows the fuel element to be secured in place within the article
