Definitions

  • the present invention relates to projectiles, such as arrows, intended to penetrate more or less deeply into a target. It also relates to ammunition containing a plurality of these projectiles, intended, for example, to be carried in vectors such as missiles, rockets, etc.
  • EP-A-0,298,494 in the name of Diehl GMBH & Co discloses an ammunition of this type, intended more specifically for the neutralization of traffic lanes or concrete tracks. It includes a set of arrows contained in a box provided with a parachute and a propellant. After dropping from a transport vector, there is first opening of the parachute, then once the verticality of the box is correct, starting the thruster. Then, once all of the propellant charge has been consumed, a second charge is ignited to expel the arrows from the housing, to provide them with additional speed relative to the latter.
  • the principle implemented in this previous invention is therefore, as in the other currently known penetrating projectile systems, to print a high speed at the arrows in the direction of the target to obtain good penetration, possibly limited by radial projections in the back of the arrows.
  • the object of the present invention is therefore to provide a new type of penetrating projectiles to overcome these drawbacks, in order to extend their field of use, while increasing their effectiveness.
  • the subject of the invention is a penetrating projectile comprising a front element forming the active part intended for penetration, integral with a tube, which tube is closed at the rear of the front element and contains a charge of propulsion thereof, and an igniter for igniting the charge, responding to the percussion of the front element against a target, said projectile further comprising a parachute attached to the rear end of the tube, intended to decrease the speed of said projectile and to bring its longitudinal axis closer to the vertical, characterized in that the igniter comprises a delay means such as the setting propellant charge fire occurs when the speed of the projectile becomes substantially zero.
  • the projectiles according to the invention comprise a front element 1 forming the active part, partially engaged in a rear part or tube 2. At least one intermediate part 10 of the element 1 is cylindrical and of the same caliber as the mouth of the tube 2, which has behind this cylindrical part 10 a retaining shoulder 20. At the front of the part 10, the element 1 has a section which decreases so as to present a front part 11 in the shape of a point clearly protruding from the outlet of the tube 2 .
  • the igniter 31 is provided to ensure the ignition of the charge 30 in response to the meeting of the front element 1 with a target, with a delay.
  • it is preferably an inertial percussion igniter, provided with a delay means for very slightly differing (by a few milliseconds for example) the firing of the charge 30 with respect to the instant of the impact.
  • This delay is provided to allow the speed of the projectile to cancel, or substantially cancel, before the firing of the charge 30; it thus frees the projectile from the penetration constraints due to the non-zero tangential component of its speed relative to the target.
  • This obliquity phenomenon characterized by the angle of the velocity vector of the projectile and the axis of the shock, in this case the vertical, is one of the major reasons for the non-penetration of the projectile into the target.
  • Element 1 has certain peculiarities of form which vary according to the application for which the projectile is intended.
  • the element 1 is an arrow for the neutralization of tracks or communication paths: it must only sink partially so as to allow a pointed or sharp part to protrude from the ground. 12.
  • the size of part 10 of element 1 is significantly greater than that of front part 11. This results in braking by part 10 and, when stationary, partial depression from it, from which follows another advantage, namely that in part 10, the arrow 1 is more difficult to cut.
  • a notch 110 of the front part 11, of the type of that of mountaineer's pitons there is advantageously provided.
  • the terminal tip portion 12 and the notch 110 in the front portion are then superfluous.
  • the difference in sizes between parts 10 and 11 although reduced, it will generally be maintained so that the depth of penetration is not too great.
  • Fig. 2 illustrates the general principle of operation of the projectiles according to the invention, although the particular embodiment of FIG. 1.
  • the projectile P arrives close to the target with a certain obliquity, and suitably oriented by means such as tailplane or, as here, parachute. Its speed is not very high, but due to a good mass / section ratio to promote penetration, when the element 1 touches the target, its tip 11 penetrates however a shallow depth, practically reaching the stop at l 'instant T2.
  • the charge 30 is ignited, generating a thrust which propels the element 1 more deeply with, in reaction, the expulsion of the tube 2 away from the element 1.
  • An additional advantage of the system is the incendiary power of projectiles when they enter tanks of flammable material (planes in the parking lot, fuel tanks, missiles, ammunition, etc.): when the rear tube 2 is ejected, hot and pressurized gases escape at high speed, accompanying the projectile in its progression. This effect can be enhanced by suitable incendiary additives in the propellant charge 30.
  • the projectile P according to the invention of FIG. 1 is intended to be ejected individually or in bundles from a transport vector. Upon ejection, it therefore has an autonomous behavior, and it is therefore provided with a means to ensure its correct orientation relative to the target.
  • This means consists of a parachute 4 housed in a retractable box 5 fixed to the rear of the tube 2.
  • the projectile P ′ of FIG. 3 is designed to form with other identical projectiles the active part of the munition M shown in FIGS. 4 and 5. It differs from the version of FIG. 2 in that, instead of a parachute, it includes a deploying tail unit formed by several fins 6 at the rear.
  • Ammunition M essentially comprises a container 7 in which are held side by side several projectiles P ′ pointed towards the exit, a parachute 8 connected by a swivel 9 to the bottom of the container 7 opposite the exit, and a chronometric sequencer to trigger the release projectiles after a predetermined time after dropping, calculated sufficient for the munition M to reach an attitude close to the vertical and a certain speed (of the order of 40 m / s).
  • the projectiles exit the container 7 by gravity, therefore without significant relative speed, by opening the container 7 or clearing a mechanical restraint. From the exit, the tail of the projectiles P ′ is deployed, for example by a spring means 60 kept loaded inside the container 7.
  • the container 7 includes means, not shown, for rotating on itself, for example aerodynamic means such as deploying fins. If the rotational speed is 10 revolutions / second at the time of the opening of the container 7, the tangential speed of the projectiles is close to 1.5 m / s assuming their center of gravity about 24 mm from the axis.
  • ammunition such as the ammunition M of Figs. 4 and 5 are perfectly suited to equip large cargo ships provided with sophisticated ejection devices allowing controlled dispersion adapted to the target, while the individual projectile version illustrated in FIG. 1 is more suitable for small freighters handling smaller areas.
  • a carrier projectile of rocket type, contains sub-projectiles in the form of arrows arranged with a single orientation (the head forward and the tail back of the rocket).
  • Propulsion means ensure the ejection of the sub-projectiles along the trajectory of the rocket, after its warhead has itself been expelled.
  • An important drawback of these munitions is that their practical range is limited by the terminal kinetic energy necessary for the correct penetration of the sub-projectiles.
  • the impact velocities are of the order of 700 m / s, while above 4,000 m, they drop below 300 m / s.
  • the kinetic energies vary in a ratio of the order of 5, and much more if one seeks an even higher range.
  • the use of tailed sub-projectiles according to the invention to equip these rockets is a solution to increase the range or even increase penetration.
