Abstract
Open breech weapon comprising a barrel having a rear end locked to a casing, a rotor rotatably mounted in said casing about an axis parallel to said barrel, said rotor comprising at least one peripheral cavity which extends parallel to the rotation axis of the rotor, control means for driving in rotation said rotor the cavity of which, during one rotation of the rotor, comes successively into opposition with a feeding position to receive an ammunition round from a feeding device, with a firing position where said cavity is coaxial with said barrel to fire the ammunition by action of a firing pin, and with an ejecting position to eject the shell of the last fired ammunition round through an ejection device. At least two arcuate segments are located between said casing and said rotor, each segment being hinged to said rotor to have an oscillating motion with respect to said rotor, and being provided with a longitudinal cavity at each end which is parallel to said cavity of said rotor, and locking-unlocking means for moving said segments in a closed position when the cavity of said rotor is in the firing position, said cavity and the cavities of said segments forming a breech of the s…
