Aerosol-generating article having a tubular support element

An aerosol-generating article having an upstream end and a downstream end, the aerosol-generating article defining a longitudinal direction extending between the upstream end and the downstream end, the aerosol-generating article comprising:

• a plug of aerosol-forming substrate at the upstream end of the aerosol-generating article;
• a hollow tubular support element positioned immediately downstream of the plug of aerosol-forming substrate;
• and
• a filter segment at the downstream end of the aerosol-generating article and positioned immediately downstream of the hollow tubular support element,
• wherein the aerosol-generating article has a length extending in the longitudinal direction between the upstream end and the downstream end,
• wherein the plug of aerosol-forming substrate has a length extending in the longitudinal direction between a first end of the plug of aerosol-forming substrate and a second end of the plug of aerosol-forming substrate,
• wherein the hollow tubular support element has a length extending in the longitudinal direction between a first end of the hollow tubular support element and a second end of the hollow tubular support element,
• wherein a ratio of the length of the hollow tubular support element to the length of the aerosol-generating article is between 0.3 to 1 and 0.5 to 1, and
• wherein a ratio of the length of the plug of aerosol-forming substrate to the length of the hollow tubular support element is between 0.5 to 1 and 0.8 to 1.
