An aerosol-generation system is between the lighting end and the tobacco portion.

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.
