摘要:
The percussion fuse is intended to be mounted on a spinstabilized projectile. The fuse includes a movable rotor subjected to the action of a retractable blocking member adapted to retain the rotor in its safety position, this blocking member being necessarily maintained in an active position by a centrifugal locking device of the percussion element of the fuse as long as this locking device remains operative; the release of this locking device permits the retraction of the blocking member under the action of return means, which retraction then permits the rotor to pass from its safety position to its armed position under the action of the centrifugal forces caused by the spin of the projectile.
摘要:
The ammunition comprises an armour-piercing shell whose body is constituted of a material which is basically a metal that oxidizes easily and that burns by heating. An axial passage is provided, in the body of the shell thus constituted, extending from the front end of the shell to a nozzle formed in the rear end of the shell. Ignition means are provided for causing, in the initial phase of the flight of the shell, the inflammation of the inner wall of the axial passage which, from that moment, behaves like a ramjet playing the role of an auxiliary propeller for the shell.
