Definitions

  • This invention relates to a weapon system or light launcher with retracting tube, for mines or anti-tank projectiles, for example.
  • Known light launchers are generally based on concepts intended to minimize the recoil impulse applied to them at the start of the projectile and thus make them capable of firing from a light lookout, or even from the shoulder. This is particularly the case with rocket launchers and so-called “recoilless" cannons. Indeed, the rockets propel themselves by reaction and, moreover, the recoil impulse caused by the launching of a projectile in a recoilless cannon is compensated by the ejection in the opposite direction, that is to say of combustion gas. , or a ballast generally divided.
  • the present invention proposes to provide a light launcher in which the mass and the cost of the system are simultaneously minimized.
  • the invention relates to a weapon or system of a light launching weapon with a retracting tube, in particular for mines or anti-tank projectiles which comprises a lookout or foresight mount, a launch tube closed at its rear part, a projectile and its propulsion charge, characterized in that said launching tube is connected to said mounting via a cradle organized so as to allow, after ignition of the propelling charge, the decoupling of the tube relative to the cradle and its free recoil, at least during the main part of the course of said projectile in the core of said tube.
  • the weapon system according to the invention makes it possible to obtain a retraction of the launching tube as free as possible by eliminating the mounting reactions liable to degrade the accuracy of the shot, the decoupling of the retreating tube and the lookout being produced in a simple and inexpensive manner and the elimination of any recoil compensating device making it possible to greatly reduce the mass of the launcher according to the invention.
  • the retreating tube can be equipped with additional elements capable of braking said tube, after ejection of the projectile, and thus reducing the range of rear effects of the proposed system.
  • FIG. 1 it can be seen that this system comprises a mount 1, a launching tube 2 closed at the rear and containing the anti-tank projectile or mine 3, launched towards the target by combustion of a propellant charge 4, for example a mass of propellant, under the effect of an igniter 5 and an ignition relay 6.
  • a propellant charge 4 for example a mass of propellant
  • the launch tube 2 is preferably made of composite materials wound on a rear insert. It can be formed from one or more connectable or deployable elements.
  • the tube 2 is integral with the carriage 1 used for pointing or prepointing, via d '' a cradle 7.
  • the bosses are arranged on the tube 2, or even on the cradle 7 of the carriage in separate sections, preferably two front sections 8 and rear section 9.
  • said tube is secured to said cradle by pinning: pins 10a, 10b ... or 10 ( Figure 2) these pins being sheared when fired.
  • the system according to the invention may include removable reinforcing pins to be removed when the system.
  • Figures 2, 3 and 4 show the organization of these bosses in the case of a first embodiment of the invention.
  • each boss of the tube such as 8T is opposite a boss of the cradle such as 8B.
  • the bosses of the launch tube 2, such as 8T and 9T constitute studs embedded in the bosses of the cradle 7, such as 8B and 9B, in the form of mortises or yokes.
  • these tenon / mortise pairs are located on the same side of the launching tube 2 and they are grooved so as to ensure the transverse maintenance of said tube relative to said cradle.
  • the invention can be used with other arrangements in particular in the search for symmetry, with respect to the axis x ⁇ x of the tube 2, of connection between the launching tube 2 and the cradle 7 in order to minimize lookout reactions.
  • bosses of the rear section 9 are offset with respect to those of the front section 8: offset in orientation or in separation with respect to the x ⁇ x axis.
  • the precision of the orientation of the tube 2 relative to the cradle 7 depends on the spacing of the boss sections 8 and 9 and on the adjustment of the couples of the bosses such as 8T, 8B or 9T, 9B.
  • said spacing is greater than the size is preferably of the order of 2 to 4 sizes while said adjustment is preferably "sliding".
  • the launching tube 2 is transversely free relative to the cradle 7 as soon as its recoil length exceeds a relatively small value, of the order of 1 / 10th of caliber for example.
  • the length (counted parallel to the axis x ⁇ x) of the bosses of the launching tube 2 and of the cradle 7, such as 8T and 8B or such as 9T and 9B, is preferably of the order of tenths of a caliber. Said cradle thus constitutes, with respect to said tube, a "zero length ramp".
  • said shear pins are made of light alloy or glass-resin composite, their section being defined so as to ensure the holding of the pin against tests. reference environment including, for example, falls, shakes and vibrations.
  • the tube 2 then shears the pins such as 10a and 10b and slides in the bearing surfaces presented by pairs of bosses such as 8T and 8B. After a course of the order of 1 / 10th of a caliber, these bearing surfaces are completely free.
  • the tube 2 is then entirely free from any mounting reaction: the aforementioned orientation or spacing offsets between the bosses of sections 8 and 9 prevent any shock or interaction between the front bosses of the tube such as 8T and the rear bosses the lookout such as 9b;
  • the tube 2 is launched in completely free recoil with a significant pulse substantially equal to the sum of that of the projectile and that of the mouth gases.
  • certain equipment such as pointing or target detection devices are mounted integrally with the tube 2; preferably on either side of the axis of said tube so that the center of gravity of the receding mass remains as close as possible to the axis x ⁇ x.
  • the system according to the invention can be completed by equipping the tube 2 with aerodynamic systems, such as parachute wings or air brake flaps, capable of deploying, preferably after ejection of the projectile or anti-tank mine 3, of so as to greatly reduce or deviate, without disturbing said projectile, the remaining speed of the tube 2 to reduce the range of rear effects of the example system of the invention.
  • aerodynamic systems such as parachute wings or air brake flaps
  • said braking or deflection effect can also be obtained by a connection of the tube 2 to the lookout 1 or to its cradle 7 only intervening after ejection of the projectile 3: this connection being for example made at by means of straps or cables.
  • the tube 2 can constitute, with the carriage and its cradle 7, a "disposable" assembly corresponding to the concept known as “the consumable weapon”.
  • the tube 2 can also constitute with the anti-tank projectile or mine 3 as well as the pyrotechnic elements 4, 5 and 6 a "complete blow" capable of being mounted by the users themselves on the cradle of the lookout 7, which corresponds to the concept of "the rechargeable weapon”.
