Definitions

  • the present invention relates to a shell magazine which is intended for preferably heavier self-propelled artillery pieces, is arranged on the elevating system and is designed in such a manner that any shell within the magazine is always available for loading into the piece. Moreover, the magazine has sufficient capacity for modern artillery tactics.
  • the propelling charges irrespective of whether these are in the form of loose charges such as cartridges or of so-called modular charges or of ready charge cases, are, on account of their very much lower weight in all these alternatives, considerably easier to handle even manually and at high loading rates.
  • the lower weight of the charges it is as a rule easier to arrange storage magazines and automatic loading functions for these.
  • the present invention relates to a shell magazine which is intended for preferably self-propelled heavier artillery pieces and is arranged on their elevating system.
  • the shell magazine according to the invention it may be mentioned that, in spite of the fact that it can be designed in order to accommodate the maximum number of shells of which the weight can be supported by the elevating system of the piece, it is nevertheless designed in such a manner that any shell within the magazine in question is always available for immediate loading.
  • the magazine is moreover designed in such a manner that fired shells can easily be replaced even if these were originally taken from different places within the magazine.
  • the magazine described therein is also of the revolver type although it comprises a number of revolvers for complete charges, where each revolver chamber accommodates two charges arranged one behind the other and only the rear charge in the respective chamber is therefore directly available for loading.
  • the artillery piece concerned is provided with a magazine which is rigidly connected to the elevating system of the piece and which extends over the elevating system, from or preferably slightly outside its one side, across the same and down along its other side, said magazine accommodating internally an endless chain conveyor which is provided with a number of compartments for individual shells, is deflected around guide wheels and the direction of, preferably mechanical, transport of which is optional, and the interior of the magazine also having guide rails along which the shells transported by the endless chain conveyor bear directly or indirectly, and also that the magazine has, in proximity to its lowest point along that part of the chain conveyor which extends down along the side of the elevating system, a discharge opening which can be opened on command and where said guide rails can be folded aside so that a shell located adjacent to this opening is then transferred to a loading bridge pivoted into said opening.
  • the loading bridge can then in turn be designed in such a manner that it has a front part which receives the shell and also a rear part in which a propelling charge, e.g. in the form of a unit charge case, the necessary number of modular charges or other propelling powder charge, can be positioned, after which the shell, preferably simultaneously with mechanical or electronic fuse programming, is backed up to form an appropriately brought-together unit with the charge, after which the shell and the charge are rammed home as a unit in the barrel of the gun in question.
  • a propelling charge e.g. in the form of a unit charge case, the necessary number of modular charges or other propelling powder charge
  • the shell magazine described purely generally above it is possible to achieve a capacity of between 20 and 30 shells in a 155 mm artillery piece and still give the piece an acceptable load profile.
  • the magazine has an upper horizontal endless chain conveyor portion which, through openable hatches in the protective shell, which should preferably surround the loading system and other splinter-sensitive parts of the piece, can easily be replenished with new shells.
  • the shell content of the shell magazine can then be replenished either by means of a crane which lifts one or more shells in from above and directly down into empty compartments in the upper horizontal portion of the endless chain conveyor, or by means of a pendulum lifting arm which is mounted in the elevating system of the piece and can be pivoted up from its one side and which has at its free end a shell cradle which is preferably equipped with special shell-clamping members and in which one shell at a time can be positioned directly from ground level in order then to be pivoted upwards/inwards by the pendulum lifting arm towards that compartment in the horizontal portion of the endless chain conveyor which is to be refilled, and when the shell cradle has reached this unloading position, the shell-clamping members mentioned previously are released and the shell is then tipped into the compartment concerned.
  • the complete artillery vehicle 1 shown in Fig. 1 comprises the actual dumper vehicle 2 which for its special function has been provided with an armoured personnel cab 3 which is designed so as to provide room for artillery personnel and also necessary data and communication equipment and also room for carrying out necessary firing calculations.
  • the elevating system 4 which comprises the gun with its barrel 5 with barrel protection 6 fixed to the gun, and two openable front hatches 6a and 6b fixed to the gun carriage, and a shell magazine 7 with splinter protection 8 which can be closed by being moved in the direction of the arrow.
  • the splinter protection 8 is open in order to make the top side of the magazine accessible.
  • a loading bridge 9 with accessories and also a ram 10 (see Fig. 2) and a small standby magazine 11 for propelling powder charges. Additional propelling powder charges are carried in the storage magazines 12 and 13 fixed to the dumper.
  • the purpose of the barrel protection 6 is on the one hand to protect the recoil system of the gun from splinter and on the other hand to screen the hot barrel from the environment so that it is more difficult to locate using IR-sensitive equipment.
  • the shell magazine 7 is provided internally with three guide wheels 14-16 (see Fig. 3), around which an endless chain conveyor 17, which in the examples shown consists of 24 interlinked shell compartments 18, is arranged in a mechanically displaceable manner.
  • the endless chain conveyor 17 forms a continuous loop with two portions 19, 20 extending one above the other over the elevating system from its one side to its other side, and two side portions 21, 22 (an inner 21 and an outer 22) extending down along its right side.
  • the shell magazine housing 7 is also provided internally with guide strips 23 (a front one and a rear one) on which the shells 24 positioned in the shell compartments 18 and, respectively, the shell compartments 18 rest and along which these are displaced.
  • All the shell compartments 18 are also open outwards away from the guide wheels 14-16. This means that the shell compartments 18 in the upper portion 19 of the endless chain conveyor 17 are open upwards and that the shells in this part of the magazine are supported entirely by the shell compartments which in turn rest on their own guide strip here. Any empty shell compartments can thus be filled from this side provided that the shell magazine 7 can be opened in this part. Accordingly, this can take place e.g. by means of a crane but can also take place using the pendulum arm illustrated in Figure 5.
  • the guide strips 23 can be opened, which means that that shell 24 which, in its compartment 18, is located at the level of this opening 25 when the guide strips 23 are moved aside will be transferred to the loading bridge 9 provided that this has been pivoted in towards the opening in question. From this position, the loading bridge 9 can be pivoted in towards the loading opening 26 of the barrel 5, after which the ram 10 is actuated.
  • a shell 24' from the shell magazine 7 has been guided down onto the loading bridge 9.
  • the latter also has room for a propelling powder charge 28, in this case in the form of a charge case which has been supplied separately.
  • a member 27 for combined fuse programming and bringing together is actuated, which engages over the front part of the shell, i.e.
  • FIG 5 only the rearmost part of the dumper vehicle 2 and the rearmost part of the elevating system 4 are shown.
  • the entire magazine 7, the loading bridge 9 and the ram 10 and also parts of a shell 24" lying on the loading bridge 9 and a propelling powder charge 28" are shown.
  • the pendulum loading arm illustrated in the figure has been given the reference number 29. It is fastened pivotably to the elevating system 4 of the gun via two bearings 30, 31. Mounted in the same bearings, so as to fold up, is a protective frame 32. In the figure, this is drawn in its folded down position. During movement, it can be folded up towards the magazine 7.
  • the pendulum loading arm 29 has a shell cradle 33 at its free outer end.
  • This cradle is provided with gripping members (not drawn in the figure) which hold a shell 24''' positioned in the same until the pendulum arm has reached its final position.
  • the refilling position of the pendulum loading arm 29 is drawn in broken lines in the figure. In this position, shells can be positioned in the shell cradle, after which the drive members (concealed in the figure) of the pendulum loading arm, in the form of a hydraulic piston assembly, pivots the arm up in the direction of the arrows B, past the position drawn in the figure, until the shell cradle 33 is located directly above the empty shell compartment 18', drawn in the figure, in the magazine 7.
  • the shell-gripping members mentioned previously are released and the shell 24''' is tipped into the shell compartment 18' and the pendulum loading arm 29 is returned to the starting position down between the arms of the protective frame 32, and at the same time the next empty shell compartment is advanced to the receiving position previously occupied by the shell compartment 18'.
  • the shell cradle 33 of the pendulum loading arm can be loaded with a new shell, either manually or mechanically, when it is in its lower refilling position between the arms of the protective frame 32.
  • the magazine system outlined above is therefore effective in terms of both action and cost.
