1. An aerosol-generating article for use with an electrically-operated aerosol-generating device, the aerosol-generating article being a consumable article, the aerosol-generating article having an outlet end and a distal end upstream from the outlet end, a middle of the aerosol-generating article located an equal distance between the outlet end and the distal end, the aerosol-generating article comprising:
a liquid aerosol-forming substrate in a frangible capsule, the frangible capsule being located between the distal end and the middle, the frangible capsule being configured to rupture by an application of an external force; and
a liquid retention medium configured to absorb the liquid aerosol-forming substrate once the frangible capsule is ruptured, at least a portion of the liquid retention medium being between the distal end and the middle, the frangible capsule being within the liquid retention medium,
the aerosol-generating article being configured to receive a heating element, the heating element being spaced apart from the liquid retention medium along the aerosol-generating article in a first direction when the heating element is received by the aerosol-generating article and the aerosol-generating article is in operational use, the first direction being parallel to a first longitudinal length of the aerosol-generating article, the aerosol-generating article being configured such that, during the operational use, air is drawn through the aerosol-generating article from the distal end to the outlet end if negative pressure is applied on the outlet end, a second longitudinal length of the heating element being collinear with at least part of the first longitudinal length of the aerosol-generating article when the heating element is received by the aerosol-generating article and the aerosol-generating article is in operational use.
