1. A cartridge assembly for use in an aerosol-generating system, the cartridge assembly comprising:
a cartridge comprising at least a first compartment extending along a longitudinal axis, the first compartment comprising an aerosol-generating compound and being sealed at a first end by a first frangible barrier extending in respective planes transverse to the longitudinal axis;
at least a first piercing member configured to rupture the first frangible barrier;
wherein the first piercing member comprises:
a first piercing body having a cross-sectional surface area at least about 40 percent of a cross-sectional surface area of the at least one compartment; and
a first channel extending parallel to the longitudinal axis of the cartridge through the first piercing body, the first channel having an inlet and an outlet;
the first piercing member being movable along the longitudinal axis from a first position to a second position,
wherein, when the first piercing member is in the first position, the first piercing body is retracted from the plane of the first frangible barrier; and
wherein, when the first piercing member is in the second position, the first piercing body extends into the at least one compartment through the plane of the first frangible barrier, and the at least one compartment is in fluid communication with the inlet and outlet of the first channel;
wherein the at least one compartment is sealed at an end opposite the first end by a second frangible barrier, the cartridge assembly further comprising a second piercing member configured to rupture the second frangible barrier; wherein the second piercing member comprises:
a second piercing body having a cross-sectional surface area at least about 40 percent of a cross-sectional area of the at least one compartment; and
a second channel extending parallel to the longitudinal axis of the cartridge through the second piercing body, the second channel having an inlet and an outlet;
the second piercing member being movable along the longitudinal axis from a first position to a second position, wherein, when the second piercing member is in the first position, the second piercing body is retracted from the plane of the second frangible barrier; and
wherein, when the second piercing member is in the second position, the second piercing body extends into the at least one compartment through the plane of the second frangible barrier, and the at least one compartment is in fluid communication with the inlet and outlet of the second channel.
