  • Patent number: 6772669
    Abstract: A method and arrangement for flick ramming projectile components such as shells or propellant powder charges in artillery pieces is disclosed which accelerates the projectile component to the necessary ramming velocity using an electromechanically generated energy supply in the form of starting acceleration from an electric motor. The rotating starting acceleration of the electric motor is mechanically converted into rectilinear acceleration, and the electric motor may be supplemented wit an energy supply obtained from a previously charged energy accumulator which is triggered simultaneously with the start of the electric motor.

  • Patent number: 6591733
    Abstract: The present invention relates to a method and a device for handling artillery shells (14-16) when loading artillery guns (1) that have an integral shell magazine (9) fixed in the traverse system but independent from the elevating mass, which magazine on command feeds out shells (14-16) one by one with a specific linear velocity in the longitudinal axis of each shell. Each shell is subsequently transferred to the loading position for the gun by a loading pendulum (13) and cradle (6). The basic idea behind the present invention is that the outfeed velocity of the shells (14-16) from the magazine (9) shall be braked to zero in a brake module (12) mounted on the gun while they lie in a shell carrier (17, 18) mounted on the loading pendulum (13).
