Definitions

  • the invention relates to a device and a method for portioning propellant charges.
  • the actual weapon is operated with separate ammunition consisting of the ammunition to be fired and a separate, ignitable to accelerate the ammunition body propellant.
  • split ammunition has the potential to If necessary, vary the amount of propellant in order to attack more distant or nearby targets.
  • the propellant charge is often composed of several propellant charge modules that can be put together on the front and bottom connecting areas to different sized propellant charges.
  • the individual propellant charge modules usually consist of a thin outer skin, for example of a cardboard material or plastic, which can be easily damaged when not properly mating or when required from time to time separation of the propellant charge modules.
  • the propellant charge modules are supplied by the manufacturer as mated packages of, for example, eight propellant charge modules, which subsequently have to be singulated before they are stowed inside the weapon system. If necessary, then a certain number of propellant charge modules is assembled to a propellant charge portion with the desired amount of propellant charge and - if, for example, in the context of maneuvers no firing takes place - then separated again.
  • propellant charge module is plugged together several times to a propellant charge and then separated again.
  • To isolate the nested propellant charge modules are usually placed on an edge and then applied to be separated propellant charge module from above with a force, whereby the connector between the propellant charge modules to be solved. Since the propellant charge modules often very tightly stuck together due to manufacturing tolerances, this can lead to unwanted damage to the outer skin of the propellant charge modules, which under certain circumstances means that they can not be used.
  • devices are known from the pipeline construction, which have two holding elements for receiving a respective tube, which are manually movable in such a way that the pipes can be joined together or separated.
  • Such devices are for example from the US 4,893,393 A. or the US 3 426 417 A known.
  • the object of the invention is to provide a structurally simple device as well as a method for portioning a propellant charge, in which the risk of damage to the propellant charge modules is low.
  • a device for portioning a propellant charge of pluggable propellant charge modules comprises two holding elements for receiving in each case at least one propellant charge module, which are manually movable against each other for portioning the propellant charge.
  • the holding elements can be coupled to one another by way of a gear mechanism such that a rotational movement of the holding elements is converted into an axial movement of the propellant charge modules accommodated in the holding elements.
  • Conceivable are various types of transmissions, which convert a rotational movement of the holding elements in an axial movement of the propellant charge modules.
  • a screw gear has proven to be particularly advantageous in terms of design, which converts the rotational movement of the holding elements in an axial movement of the propellant charge modules, through which the plug connection between the propellant charge modules can be produced or separated.
  • Such a configuration allows a structurally simple, independent of external energy sources construction of the device for portioning the propellant charge.
  • the propellant charges can be portioned in a simple manner.
  • propellant charge modules can be plugged together to form a larger propellant charge or put together propellant charge modules, without doing so Damage to the propellant charge modules are to be feared.
  • the holding elements are designed such that they hold the propellant charge module under pressure.
  • the propellant charge modules can be kept in a simple manner in the holding element and released by discharge again.
  • the holding elements have two pincer-like articulated clamping elements.
  • the required holding pressure can be manually applied to the propellant charge modules.
  • plungers are arranged for conditioning of the propellant charge module.
  • the pressure pieces made of a rubber-elastic material, resulting in a shell of the propellant charge modules gentle system.
  • the plungers may be designed so spring loaded that their spring spans when creating the plungers to the propellant charge modules. This results in a defined pressure limitation, by which damage to the propellant charge module is avoided.
  • the clamping elements have handles by means of which the clamping elements can be tensioned against the propellant charge modules.
  • the clamping elements By gripping the handles, a relative movement between the two holding elements can be generated in this way at the same time and the required holding pressure is exerted on the propellant charge module which results in a particularly user-friendly design.
  • the holding elements for portioning the propellant charge can be coupled to one another. After the two holding elements have been coupled together, a defined relative movement of the holding elements and thus the propellant charge modules can be generated via the coupling.
  • a further embodiment provides that one of the holding elements has a groove and the other has a slot nut which can be introduced into the groove.
  • the movement of the sliding block within the groove results in a structurally simple manner a guided movement of the holding elements.
  • the groove has an axially extending axial region and an angle extending obliquely contrasting.
  • the nut can, depending on whether a disconnect or mating of two propellant charge modules is desired, either enter the groove over the oblique region or over the axial region.
  • propellant charge modules are moved against each other via a device of the type described above.
  • propellant charge modules can be plugged together to form a larger propellant charge or put together propellant charge modules, without causing damage to the propellant charge modules to be feared.
  • the two holding elements are first attached to at least one propellant charge module and then coupled together.
  • the mutually coupled holding elements are rotated against each other and the rotational movement of the holding elements is converted into an axial movement of the recorded in the holding elements propellant charge modules. This makes it possible to achieve a defined portioning of the propellant charge.
  • Fig. 1 shows a holding element 3 of the two of the basic structure similarly designed holding elements 3, 4 existing device 1, see. also Fig. 3 ,
  • the two holding elements 3, 4 serve to receive a respective propellant charge module 2 and can be manually moved against each other for portioning a propellant charge composed of two propellant charge modules 2.
  • the propellant charge module 2 is received in the interior of the holding elements 3, 4 and held in the manner of a pair of pliers under pressure.
  • the holding elements 3, 4 have two clamping elements 5, 6 connected via a joint 7, which in the exemplary embodiment are designed in the manner of half-shells.
  • the clamping elements 5, 6 are each provided with handles 10, 11, in which an operator by hand penetrate and in this way a pressure on the between the clamping elements 5, 6 arranged propellant charge module 2 can muster. At the same time can be generated on the handles 10, 11, a relative movement between the two holding elements 3, 4, which will be discussed in more detail.
  • pressure pieces 9 are provided on the inner side 8 of the clamping elements 5, 6, by means of which the pressure is applied to the casings of the propellant charge modules 2 at several points.
  • the plungers 9 are made of a rubber-elastic material, which can produce a uniform pressure distribution on the envelopes of the propellant charge modules 2.
  • the pressure pieces 9 are biased by a spring tensioning mechanism not shown in detail in the direction of the propellant charge modules 2, so that the pressure pieces 9 against a pressure on the propellant charge modules 2 against the pressure of the spring in the direction of the inside 8 of the clamping elements 5, 6 move, which can limit the pressure applied to the propellant charge modules 2 pressure.
  • the device 1 consists of two separate holding elements 3, 4, which can be coupled to each other for portioning the propellant charge, as hereinafter with reference to the representations in the Figures 2-8 will be discussed, which illustrate the processes when separating two propellant charge modules 2.
  • Fig. 2 shows in perspective view two propellant charge modules 2, which are frontally plugged together.
  • the propellant charge modules 2 have, in the region of their one end face, a plug-in area which is reduced in relation to the remaining diameter of the propellant charge module 2 and which can be plugged into a correspondingly shaped recess in the bottom side of an adjacent propellant charge module 2.
  • the one holding device 3 is first placed on a propellant charge module 2. Subsequently, the second holding device 4 is placed on the adjacent propellant charge module 2. Subsequently, the two holding elements 3, 4 are coupled together via a gear 12, cf. also the representation in Fig. 3 in which the transmission area is shown transparent for the purpose of illustration, whereby the internal gear components are visible.
  • the serving for coupling the holding elements 3, 4 gear 12 is formed in the embodiment in the manner of a screw gear.
  • a holding device 3 in the region of its on the other holding device 4th assigning end on a groove 13.
  • the groove 13 consists of an axially extending in the axial direction of the propellant charge modules 2 Axial Scheme 13.1 and a beveled with respect to the axial region 13.1 inclined region 13.2.
  • Both the axial region 13.1 and the oblique region 13.2 terminate in one end face of the retaining element 3, which is why a sliding block 14 can be introduced from the axial direction into both the axial region 13.1 and the oblique region 13.2 of the groove 13.
  • the sliding block 14 is arranged on the inside of an annular region 14.1 arranged on the retaining element 4 and points in the direction of the interior of the retaining element 4.
  • the holding element 4 and with this the sliding block 14 relative to the support member 3 are moved.
  • the sliding block 14 enters the axial region 13.1 of the groove 13 until the in Fig. 3 shown end position is reached, in which the sliding block 14 is located in the transition between the axial region 13.1 to the oblique region 13.2 of the groove 13.
  • Fig. 5 a position is shown in which the sliding block 14 has reached the end of the oblique portion 13.2 of the groove 13. In this position, the propellant charge modules 2 are separated from each other, see. also the representation in Fig. 6 ,
  • the retaining elements 3, 4 are again decoupled from each other after leaving the sliding block 14 from the inclined area 13.2 and the propellant charge modules 2 are separated from each other, cf. also the representations in the FIGS. 7 and 8 ,
  • the sliding block 14 does not enter via the axial region 13.1 in the groove 13, but on the inclined portion 13.2, so that upon mutual rotation of the holding elements 3, 4 facing one another axial movement the propellant charge modules 2 is generated, which causes the propellant charge modules 2 are connected to each other at the front and bottom.
  • the above-described device 1 for portioning propellants is characterized by a comparatively simple, independent of external energy sources construction and is easily operated by untrained operators. Damage to the propellant charge modules 2 are avoided even with multiple connection or disconnection.
