Fuente: WIPO "tomato" AEROSOL-GENERATING ELEMENT FOR USE IN AN AEROSOL-GENERATING ARTICLE OR SYSTEM There is provided an aerosol-generating article for generating an inhalable aerosol upon heating, the aerosol-generating article comprising: a longitudinally extending aerosol-generating element; and a downstream section at a location downstream of the aerosol-generating element. The aerosol-generating element comprises a core body and an air-permeable shell portion circumscribing the core body, the shell portion comprising a primary aerosol-generating substrate and defining an airflow path through the shell portion. The core body is substantially free of the primary aerosol-generating substrate. A cross-sectional area of the core body is at least 3 percent of an overall cross-sectional area of the aerosol-generating element. (Figure 1)
