Abstract
A smoking article is provided, having opposed lighting and mouth ends, and including a mouth end portion at the mouth end. A tobacco portion is between the lighting end and the mouth end portion. An aerosol-generation system is between the lighting end and the tobacco portion. The aerosol-generation system includes a heat generation portion, comprising an elongate fluted member actuated by ignition of the lighting end. The fluted member defines grooves extending longitudinally between opposed first and second ends, with the first end being at the lighting end and the grooves being equidistantly spaced apart about the fluted member. Each groove has a maximum depth. The depth maxima of the grooves define a circle having a radius. The maximum depth of each groove is no more than the radius of the circle. A heat generation apparatus for an aerosol-generation system of a smoking article is also provided.
