1. An ejection assembly, for ejecting an ejection body, comprising:
an ejection channel having an open end, for conveying an ejection gas pressure pulse and the ejection body to exit the distal open end;
an anti-recoil channel having an open end, for conveying an anti-recoil gas pressure pulse to exit the distal open end;
a barrier structure having a first interface boundary and a second interface boundary , including a barrier portion between the first interface boundary and the second interface boundaries;
an attachment mechanism for fastening the barrier structure between the ejection channel and the anti-recoil channel, the open end of the ejection channel disposed opposite and remote from the first interface boundary, and the open end of the anti-recoil channel disposed opposite and remote from the second interface boundary;
characterized in that:
an ejection activation mechanism is housed within the barrier structure adjacent the first interface boundary, operable to initiate, in response to receiving an ejection signal, combustion of ejection propulsion material contained in an ejection capsule placed adjacent the first interface boundary and thus producing the ejection gas pressure pulse for driving the ejection body through the ejection channel to exit the distal open end;
an anti-recoil activation mechanism is housed within the barrier structure adjacent the second interface boundary, operable to initiate, in response to receiving an anti-recoil signal, combustion of anti-recoil propulsion material contained in an ejection capsule placed adjacent the second interface boundary and thus producing the anti-recoil gas pressure pulse; and
wherein the barrier portion prevents pressure communication between the ejection gas pressure pulse in the ejection channel and the anti-recoil gas pressure pulse in the anti-recoil channel.
