Abrégé

An ejection assembly (100)for ejecting an ejection body comprises an ejection channel (110)and an anti-recoil channel (120); a barrierstructure (130)having a first interface boundary (138A) and a second interface boundary (138B), including a barrier portion (132) between the first interface boundary (138A) and the second interface boundaries (138B); an attachment mechanism (136A, 136B) for fastening the barrier structure (130) between the ejection channel (110) and the anti-recoil channel (120); an ejection activation mechanism (140A) housed within the barrier structure (130) adjacent the first interface boundary (138A), to initiate ignition of ejection propulsion material contained in an ejection capsule placed adjacent the first interface boundary (138A); and an anti-recoil activation mechanism (140B) housed within the barrier structure (130) adjacent the second interface boundary (138B), to initiate the ignition of anti-recoil propulsion material contained in an ejection capsule placed adjacent the second interface boundary. The barrier portion (132) preventspressure communication between an ejection gas pressure pulse in the ejection channel (110) and ananti-recoil gas pressure pulse in the anti-recoil channel (120), to reduce recoil of the ejection assembly (100).
