Definitions

  • the present invention relates to a cargo shell whose base is parachute jar office of a submunition. It applies in particular to shells containing submunitions equipped with parachutes and intended to be dropped by these shells.
  • Some shells may contain several submunitions stacked one after the other. These submunitions are generally equipped with a parachute slowing their fall towards the ground. Each submunition is then equipped at the rear with a containment pot now his parachute folded. They are ejected from the shell from the rear of this one following the combustion of a pyrotechnic charge of stripping commanded chrono-metrically at the front of the shell.
  • German patent application DE 3,635,361 the description of which summarizes the preamble of independent claim 1, presents a shells with submunitions equipped with parachutes.
  • the submunitions Although ejected from the shell from the rear, the submunitions nevertheless continue their course according to the direction and direction of the shell at time of ejection. At this time, the submunitions remain stacked as they were in the shell. Their ejection having taken place from the rear, this which advantageously contributes to slowing them down, it follows that the base of the shell accompanies them in their race, from the rear. Submunitions before opening their parachute should generally be slowed down. In this Indeed, they each have their own braking means, a small parachute or flexible sipes deploying laterally, for example.
  • These submunitions can be equipped with fragile elements, sensors in particular, sensitive to mechanical shock. It is therefore necessary when the braking phase, that the submunitions do not collide. In especially the base must be braked more strongly than the submunitions in order let him not come up against them. This requires equipping it with means more braking than those in submunitions, so relatively bulky.
  • the object of the invention is to overcome the aforementioned drawbacks.
  • the invention relates to a shell as described in the claim 1.
  • the main advantages of the invention are that it increases the volume available inside the shell, which eliminates the risk of shocks between the submunitions and the shell of the shell, finally that they decrease the number of elements therefore the cost of the shell.
  • Figure 1 shows a shell 1, having a envelope 11 and containing unloading means 7 and submunitions 3, 5.
  • the shell 1 is closed by a base 2 according to prior art.
  • the submunitions 3, 5 are equipped on their part rear of parachutes contained in pots 4, 6 closed by submunitions.
  • the base 2 is capable of supporting on its external face 8 of very strong pressures, in particular at the time of its launch by a cannon; these pressures can for example reach 4000 bars.
  • the base 2 also includes means for braking 9, not deployed when it is integral with shell 1.
  • the base 2 is for example screwed onto shell 1 so as to maintain solidarity with it.
  • the submunitions are ejected following the combustion of a gas generator unloading 7 for example, placed in front of the shell. This combustion is started after a delay predetermined by example using a chronometric rocket.
  • the pressure pushes submunitions 3, 5 towards the rear of shell 1, the thrust being strong enough to separate base 2 from the shell 1 by destroying the means 10 for holding the base 2 on the shell 1, these holding means 10 can be a thread by example, allowing to screw the base 2 on the shell 1.
  • the submunitions 3, 5, ejected from shell 1 from the rear nevertheless continue their course in the same direction and the same direction as the shell with a lower speed because of the thrust they suffered.
  • Base 2 has the same speed that submunitions 3, 5 and therefore accompanies them in their race.
  • Figure 2 illustrates the relative position of the submunitions 3, 5 and pellet 2 after their ejection from the shell 1.
  • the submunitions 3, 5 are always provided with their pots 4, 6 in order to protect and keep folded their parachutes.
  • braking means 21, 22, lamellae for example are deployed and put into action to slow the speed of submunitions 3, 5.
  • the braking means 9 of the base 2 also slow it down. They must act in such a way that it does not come up against the submunition 5 placed directly in front of him. To avoid any risk of shock, it must be slower than submunitions 3, 5. It follows that its braking means 9 must be significant and therefore bulky.
  • FIG. 3 shows a possible example of shell 1 produced according to the invention.
  • This shell contains means of stripping 7, a gas generator for example, and submunitions 3, 5 identical to those of the preceding figures. It contains at the rear a submunition 31 whose body is identical to the bodies of other submunitions 3, 5 but whose jar containing its parachute is constituted by the base 2 of shell 1.
  • Pellet 2 while being integral with the submunition 31 is held integral with shell 1 by holding means 10, a thread for example allowing it to be screwed on the shell.
  • the base 2 can also for example be made integral shell 1 by means of screws and pins likely to be sheared, means known to those skilled in the art.
  • the submunition 31 is secured with the base 2 to using screws for example.
  • the submunitions 3, 5, 31 are ejected from shell 1 from the back of it, as previously described, i.e. following a combustion of the gas generator unloading 7 at the front of shell 1 and following the destruction of means 10 for holding the base 2 on the shell 1.
  • Figure 4 shows submunitions 3, 5, 31 after their ejection from shell 1 continuing their course in the same direction than this one.
  • the parachutes not yet being deployed, the pots 4, 6, 2 are still integral with the submunitions 3, 5, 31.
  • the parachute jar of the submunition 31 which was placed at the rear of shell 1 is in makes the shell of this shell 1. This one contains in its interior 42 the parachute of the submunition 31.
  • the base 2 being integral with the submunition 31, it no longer risks colliding with it.
  • the braking means 41 may for example be deployed slats.
  • Base 2 having had to undergo strong pressures when ejecting shell 1 from a cannon, this base 2 serving as a parachute jar for the submunition 31 is more resistant, therefore heavier than the others pots 4, 6 of the other submunitions 3, 5. Consequently, the braking means 41 of the submunition 31 are more powerful than those of other submunitions 3, 5.
  • these braking means 41 being common to submunition 31 and at base 2, braking of the base no longer wastes space inside the shell 1, since these braking means are shared between the submunition 31 and base 2.
  • the shell base according to the invention by acting as a pot the parachute allows increase the number of submunitions inside the shell.
  • Figure 5 illustrates the deployment of parachute 51 of submunition 31 by separating it from its pot or shell 2. This separation can be for example triggered according to a predetermined delay.
  • the means maintenance and separation of base 2 from submunition 31 are identical to those of other submunitions 3, 5, the separation means can for example be means pyrotechnics.
  • To allow the deployment of parachute 51 this one is connected at one of its ends to a rope 52, itself connected to the base 2. Under the action of force drive base 2 whose thrust is direction opposite the speed of the submunition 31, the rope 52 cut when the parachute 51 is completely unfolded.
  • shells according to the invention presented by the figure 3 contains three submunitions, this number is given to title of example and can vary in particular according to the length of shell or submunitions, or following other settings.
