Definitions

  • the invention relates to a method of ejecting submunitions from a projectile whose natural roll speed is zero or low. It also relates to a projectile equipped with means allowing the implementation of this process.
  • projectile any vehicle launched by cannon, by self-propulsion, by aircraft, etc., and following a ballistic or corrected trajectory.
  • the invention relates more precisely to projectiles comprising sub-projectiles ejected at a given time on the trajectory of the carrier projectile.
  • Patent application EP-A-0.270.401 filed by the Applicant, describes for example a projectile comprising sub-projectiles ejected in a controlled direction. To do this, the sub-projectiles are equipped with a fixed tail, stored in a unique orientation, the residual gaps being filled with a powdery material.
  • the present invention aims to overcome these drawbacks and relates to a new method of ejecting submunitions from a projectile whose natural roll speed is practically zero, a method which has the advantage of being part of the same sequence opening the vehicle without the need for additional heavy, bulky and expensive means.
  • this projectile (1) As shown in FIG. 1, supplemented by FIG. 2 which represents the projectile of FIG. 1 in a configuration corresponding to the ejection of the submunitions, this projectile (1) according to the invention comprises an envelope (2) generally cylindrical ending in a warhead (3).
  • the latter is itself integral with an axial rod (4) intended, as will be explained below, to play a piston function.
  • the rod (4) enters a tube (5) integral with the rear part (base 13) of the projectile (1), leaving at the end a free space (chamber 6) occupied by a pyrotechnic charge (not shown in the figure).
  • the tube (5) is scratched and the rod (4) receives a forcing belt or machined teeth.
  • the combination (100) "stripes of the tube + forcing belt or teeth” is symbolized by a reinforced line in the figure, and this for the purpose of clarity.
  • This combination induces a rotational movement. It allows the implementation of the method of ejecting the submunitions (20) contained in the projectile (1).
  • the pyrotechnic charge is started by taking care to carry out the prior or simultaneous unlocking of the means (12) for securing to the base (13 )
  • the rod (4) plays its piston function and, as shown in FIG. 2, ejects the warhead (3), this ejection taking place with a rotational movement in a given direction (arrow f1) for the front of the projectile and an opposite direction (arrow f2) for the rear part.
  • the pitch of the scratches is chosen so as to obtain a roll speed of the rear part which results in an optimal transverse ejection speed (v) of the submunitions (20) depending on their initial distance to the axis (xx ') of the projectile (1).
  • this projectile comprises the casing (2) integral with the axial rod (4) which penetrates into the striped tube (5) thanks to the combination 100 as previously described.
  • this tube (5) are fixed, for example, elements (14), for example, metallic, to establish compartments (16) inside which the submunitions (20) are positioned.
  • the set of submunitions (20) is held in each compartment by holding means, for example, a belt (15) controlled, for example, by an explosive system not shown, which ensures that all of the tube submunitions (5); these holding means are generally unlocked when the assembly of submunitions (20) and tube (5) has reached a maximum speed which constitutes the initial speed of the submunitions (20) after ejection of the warhead (3) but they can be unlocked in a delayed manner and for each compartment.
  • holding means for example, a belt (15) controlled, for example, by an explosive system not shown, which ensures that all of the tube submunitions (5); these holding means are generally unlocked when the assembly of submunitions (20) and tube (5) has reached a maximum speed which constitutes the initial speed of the submunitions (20) after ejection of the warhead (3) but they can be unlocked in a delayed manner and for each compartment.
  • FIG. 4 which illustrates an alternative embodiment of the invention, a reverse architecture is produced.
  • the rod (4) acting as a piston is this time made integral with the base (13).
  • the tube (5) and the chamber (6) are then made integral with the warhead (3).
  • the submunitions (20) are connected to the rear part, that is to say to the base (13 ) by any known means (30); Whichever variant is chosen, a roll speed is thus obtained when the submunitions are released, which gives the submunitions a transverse ejection speed.
  • Axial inertias front part I1 1.13 m2 kg.
  • rear part I2 1.97 m2 kg.
  • This last speed is to be added to the initial roll speed of the vehicle, if it exists. If this speed is 10 turns / s and the submunitions are placed between 54 mm and 120 mm from the axis (xx ′) of the projectile, the ejection speeds perpendicular to this axis are between 9 and 20 ms ⁇ 1.
