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.

Abstract: The present invention relates to a method and a device designed for use with such shells (1) that are equipped with a base-bleed unit (8) for extended range and which during the first phase of their trajectory are spin-stabilised but which in the subsequent phase are subjected to spin deceleration by fins (9-13) that deploy from the shell body and take over the stabilising function. More exactly the present invention is a method and a device that enables the said shells (1) to achieve an effective and functional deployment of the fins (9-13) at the desired point in time with simultaneous ejection of the base-bleed unit (8) which at this point in time either no longer performs any useful function since it is burnt-out and solely constitutes a dead-weight or its function is no longer required.

Abstract: The present invention relates to a method and a device relating to shells with deployable fins and which are fired from large caliber guns into ballistic trajectories, for preventing the propellant gas pressure in the barrel during firing from directly or indirectly deforming the said fins (9-13). The type of fins that the present invention primarily relates to are those that are deployed on command in order to fin-stabilize the shell. Usually such fins are protected prior to deployment by an ejectable fin protector (19). To prevent this fin protector from being deformed and consequently impeding fin deployment or degrading fin functionality, the present invention proposes that all unoccupied space inside the said fin protector be filled with an inert, noncombustible, non-glutinous substance (32) of low compressibility and very low inherent strength.

Abstract: The present invention relates to a propellant charge module for artillery guns, of the type which is usually referred to by the term “modular charges” (1). A special feature of this type is that, in an otherwise empty pyrophoric relay tube (10) arranged axially in the longitudinal direction of the charge, it has a firing charge which is made up of a plurality of successive powder rings (14), the different ring-shaped parts of this firing charge having distancing members (16) which are directed towards each other and give rise to narrow ignition gaps (18) between them.
