Aerosol delivery system

An aerosol-generation apparatus comprising a heater and a fluid-transfer article, said fluid-transfer article having a first region for holding an aerosol precursor and for transferring said aerosol precursor to an activation surface of a second region of said article, said activation surface being disposed and configured for thermal interaction with a heating surface of said heater;

• said second region comprising at least one discontinuity in said activation surface to form a corresponding at least one channel between said second region and said heating surface and being configured such that, when the fluid transfer article is arranged with respect to said heating surface of the heater for thermal interaction therebetween, the or each channel opposes said heating surface, opens towards said heating surface, and provides an air-flow pathway across said heating surface;
• wherein the heater comprises a substrate defining said heating surface, and at least one heating element formed on a part of said heating surface, and said at least one channel opposes a further part of said heating surface other than said part of said heating surface on which said heating element is formed.
