Definitions

  • the present invention relates to a method and a device for stowing, transporting, and on command delivering projectiles of any elective type and propellant charges of any elective type to an artillery gun with integral magazine system, and for an arnmunition resupply vehicle designed for this purpose.
  • propellant charges of modular type i.e. propellant charges consisting of a number of modular charges of different sizes such as length and. to a certain extent, diameter and of different charge strength with p ⁇ ma ⁇ lv ⁇ gid combustible outer casing, and that are combmable m various ways to provide the desired muzzle velocities.
  • M(A)CS Modular (Artillery) Charge System.
  • next generation loading systems will be required to operate very rapidly and be capable of stowing large quantities of propellant charges and of handling all the different types of propellant charges in the M(A)CS.
  • the modular charges must also be stowable in the least possible space.
  • loading systems shall be robust and durable, and the modular charge magazine shall be replenishable in a very short time, preferably from a vehicle equipped with an automatic resupply unit.
  • the number of different types of projectile is also expected to increase during the next few years and it is also considered that new, extremely long projectiles to maximise range will also be introduced.
  • the present invention relates to a method for stowing, transporting, and resupplying modular charges and projectiles from a transport vehicle of the type indicated above and the design of the transport vehicle in question.
  • the present invention is based on a consistent use of a replenishment module designed for modular charges and projectiles that utilises the ribbon conveyor principle with indexable outfeed.
  • the modular charge magazine incorporated must be able to handle many different types of modular charges that — even though they have the same outer diameter on the whole — may have markedly different lengths.
  • the modular charge magazine is therefore based on a logical utilisation of mutually parallel magazine tubes linked to the ribbon conveyor, each magazine tube being capable of accommodating a greater or smaller number of modular charges of preferably the same charge strength.
  • the projectile magazine incorporated may also be based on indexable feed magazine tubes linked to a ribbon conveyor, each magazine tube preferably designed to accommodate one projectile.
  • Each projectile constitutes a rigid unit whose length — even though it may vary between types of projectile — will never be less than a specific substantial minimum dimension.
  • the ribbon conveyor performs only a feed function that drives the projectiles around a closed loop in guide rails which loop has an outfeed aperture openable on command.
  • This version requires at least two pairs of ribbon conveyor guide rails, each pair arranged at a distance from each other equivalent to the diameter of the projectiles plus the necessary play, while the ribbon conveyor drive chain comprises combined positioning and feed teeth that ensure that the projectiles — both when the ribbon conveyor is stationary and when it is running between the guide rails — are kept at right angles to the path formed between the guide rails.
  • the magazine tubes for the modular charges are designed for outfeed forwards by means of an ejector operating in the rear end of each magazine tube while the magazine tubes for the projectiles, to the extent that such are used, are primarily designed to open longitudinally between two hinged tube halves.
  • the intention is that when projectile magazine tubes open, or when a projectile is fed along the guide rail system to the previously mentioned outfeed aperture, the projectiles shall be fed down into a linear conveyor that feeds the projectiles one- by-one to a dedicated download tube in a boom device designed for direct connection to the replenishment hatch in the artillery gun into which the new projectiles are to be downloaded.
  • the said boom is also designed to accommodate a second download tube for the modular charges.
  • Figure 1 shows an exploded view of an ammunition resupply vehicle as claimed in the invention
  • Figure 2 is a cross-section of the same vehicle to a somewhat larger scale
  • Figure 3 is a more detailed diagonal projection of part of one version of the projectile magazine relating especially to its outfeed function, while
  • Figure 4 is a plane view to a larger scale of part of another version of the projectile magazine.
  • Figure 5 is a cross-section though the magazine illustrated in Figure 4 showing the outfeed function of this version of the projectile magazine.
  • number 1 is a six-wheel all-terrain vehicle with articulated steering equipped with a lightly armoured front-mounted engine and crew cab 2 and a rear-mounted replenishment module 3.
  • the latter incorporates a modular charge magazine 4 comprising a large number of magazine tubes 5 for stowage of modular charges (MC), all such MC magazine tubes interlinked with each other by non-illustrated hinged links to an indexable feed ribbon conveyor to form the loop 6.
  • MC modular charges
  • arrow 7 denotes the position and direction of operation for an ejector that can be actuated in any MC magazine tube 5 when it is aligned with the download tube for modular charges (designated 8 in Figure 2).
  • This download tube is incorporated in the boom 9 extending over the roof of the crew cab 2.
  • the download aperture 10 of the said boom is designed to interface with a replenishment aperture in the magazine of the artillery gun that the resupply vehicle is to resupply with modular charges and projectiles.
  • boom concept in fact, is already known, and the feed function required in the boom to feed the modular charges and projectiles through their respective download tubes is therefore not described in detail but may, for example, consist of mechanically driven toothed belts of conventional type rurining over a number of pulleys.
  • the boom 9 thus also incorporates a download tube 22 for downloading projectiles in parallel with the modular charges.
  • the projectile magazine 3 in the example illustrated consists of three magazine sections 11-13, each one designed as an independently driven, indexable loop of interlinked projectile magazine tubes 14 each accommodating one projectile.
  • each such projectile magazine tube 14 comprises two halves 15 and 16 that can be opened by a non-illustrated device when the projectile magazine tube in question is in a conveyor stop position immediately adjacent to a linear feed module 17 which is illustrated in the figure as path 18 for a projectile carrier 19, but which could just as easily consist of a toothed conveyor running over pulleys for transporting forwards any projectiles placed into it.
  • conveyors in the magazines can be driven in either direction, as required.
  • a projectile hoist which is not illustrated in the figures, is used when replenishing the projectile magazine and lifts the projectiles over from the projectile carrier or conveyor 19 and into the relevant projectile magazine tube as per the version illustrated in Figure 3, or into the stowage compartments formed by the ribbon conveyor 28 between the guide rails 24-27 as per the version illustrated in Figures 4 and 5, i.e. the function is thus driven in reverse in principle.
  • the feed principle for the projectiles in the stowage loop of the magazine illustrated in Figure 3 may also be modified in the manner shown in Figures 4 and 5.
  • the projectiles designated 23 in Figures 4 and 5 are fed between guide rails 24-27, driven by a drive chain 28 running over non-illustrated pulleys.
  • Drive chain 28 incorporates teeth to keep the projectiles correctly positioned and to ensure that the projectiles are kept at right angles to the tensioning direction of the guide rail system.
  • FIG. 5 there is also an outfeed aperture 31 indicated where the outer guide rails 24 and 26 can be opened. When open the first projectile that reaches the aperture will be transferred to the linear feed module 32. Number 33 indicates an opening mechanism for the outfeed aperture 31. If the latter is closed the projectiles can continue to be fed around the loop without problem.

Abstract

L'invention concerne un procédé de rangement, de transport et d'alimentation à la demande de projectiles (20) et de charges propulsives de tous types. Ce procédé destiné à une pièce d'artillerie à système chargeur intégré se met en oeuvre à partir d'un véhicule de ravitaillement en munitions (1). L'invention se distingue par l'utilisation rationnelle, selon le principe du transporteur à ruban, des chargeurs de rangement contenant des types spécifiques de charges explosives et de projectiles.
