Definitions

  • the present invention relates to improvements made to ammunition for cannons, mortars and similar weapons equipped with a recoil damping device. It applies more particularly to high impulse munitions.
  • This organization has the particular disadvantage of being cumbersome, cumbersome and limiting as regards the admissible recoil energies.
  • an ammunition for cannons, mortars and similar weapons of the type comprising a shell containing a projectile, which comprises at least two propellant charges: a charge for ejecting the projectile and, at least one charge launching the projectile the latter being initiated by the hot pressurized gases from the complete combustion of the ejection charge and a system of chambers through which are released, in the passage of the projectile, the combustion gases of said charge d ejection, this system comprising: a first chamber receiving the combustion gases from the ejection charge and operating under high pressure a second annular chamber, or intermediate ignition chamber receiving the combustion gases from the projectile launch charge and ; a third chamber or main chamber for combustion and expansion of the munition, operating under a lower pressure than that prevailing in the first chamber and into which said second chamber opens.
  • the present invention proposes to increase the potential of these weapons by providing provisions making it possible to limit the recoil energies by implementing appropriate internal ballistics. .
  • the structure containing the launch charge comprises peripheral ignition lights closed by an ignition composition and this structure is provided with an openwork shutter member, the nozzles of which provide ejection combustion gases from this launch charge.
  • the ammunition comprises a cruising propellant or a drag compensator, initiated by the combustion gases of the ejection charge filling said first chamber.
  • FIG. 1 represents the ammunition according to the present invention which comprises, as known, a cartridge case 1 containing the projectile 2 provided with a sealing ring 3.
  • the pressure generated by the combustion and ignition gases filling the chamber 7 allows the projectile 2 to move inside the socket 1.
  • the projectile 2 discovers in the intermediate ignition chamber 13, the second propellant charge 10, the initiation of which is provided by the ignition composition 11 which is contained in the cells peripheral to the structure containing the ignition charge 10, this initiation being carried out by the stream of hot gases and under pressure originating of chamber 7 and resulting from the combustion of the ejection charge 4 (and possibly in in addition to the cruising thruster 8 or a drag compensator), this stream of gas flowing from the periphery towards the interior of the load 10.
  • This operating phase is illustrated in FIG. 2.
  • the gases produced by the ignition of the launch charge 10 are ejected by the nozzles of the shutter means 12, the latter thus ensuring a uniform gas flow inside the charge 10 and the maintenance of a certain pressure ignition, before the release of the main chamber 14 while the projectile continues its movement.
  • the gases then fill the main chamber 14 as illustrated in FIG. 4, the seal being ensured by the ring 3.
  • the operating pressure is lower than during the previous phase but it applies to a section larger, which increases the launching pressure of the projectile giving it its initial speed.
  • the present invention makes it possible to modify the interior ballistics of a munition by providing at least two pulse stages, for launching the projectile, which ensures a reduction in the recoil energies.
  • the ammunition improved according to the present invention can be used in a long gun as described and claimed by the present holder in his patent application filed on the same day as the present application and entitled "long gun for firing ammunition with strong impulse ".

Claims (3)

  1. Munition für Kanonen, Mörser und ähnliche, mit einem Rückstoßdämpfersystem ausgerüstete Waffen von der Art, daß sie eine ein Projektil enthaltende Hülse aufweist, wobei diese aufweist:
    - mindestens zwei koaxial angeordnete Treibladungen;
    eine Ladung (4) zum Austreiben des Projektils (2),
    mindestens eine Ladung (10) zum Abschuß des Projektils, die durch die heißen, druckbeaufschlagten, aus der vollständigen Verbrennung der Ladung zum Austreiben (4) hervorgegangenen Gase gezündet wird;
    - ein System von Kammern, über die beim Passieren des Projektils die Verbrennungsgase der Ladung zum Austreiben freigesetzt werden, wobei dieses System aufweist:
    eine erste Kammer (7), die die Verbrennungsgase der Ladung zum Austreiben (4) aufnimmt und unter hohem Druck arbeitet;
    eine zweite ringförmige Kammer (13) oder mittlere Zündungskammer, die die Verbrennungsgase der Ladung zum Abschuß (10) des Projektils aufnimmt und
    eine dritte Kammer (14) oder Hauptkammer der Verbrennung und Entspannung der Munition, die unter einem niedrigeren Druck als dem arbeitet, der in der ersten Kammer (7) herrscht, in die die zweite Kammer mündet,
    dadurch gekennzeichnet,
    daß
    - die Ladung zum Austreiben (4) in einem mit der Hülse (1), die das Projektil enthält, fest verbundenen Stutzen (6) angeordnet ist, der in die erste Kammer (7) mündet;
    - die Ladung zum Abschuß (10) am Ende des Stutzens in einer zu diesem Stutzen konzentrischen Struktur außerhalb des Stutzens angeordnet ist, wobei diese Struktur in die zweite Kammer (13) mündet, die zwischen dem Innendurchmesser des Endstücks des Projektils und dem Außendurchmesser der Struktur der Ladung zum Abschuß (10) eingepaßt ist.
  2. Munition gemäß Anspruch 1,
    dadurch gekennzeichnet,
    daß die die Ladung zum Abschuß (10) enthaltende Struktur an ihrem Umfang Schlitzlöcher (11) zur Zündung aufweist, die durch eine Zündungszusammensetzung verschlossen sind, und daß diese Struktur mit einem durchbrochenen Verschlußmittel (12) ausgestattet ist, dessen Durchbrüche den Ausstoß der Verbrennungsgase der Ladung zum Abschuß sicherstellen.
  3. Munition gemäß einem der Ansprüche 1 oder 2,
    dadurch gekennzeichnet,
    daß die Munition eine Flugtreibladung (8) oder einen Widerstandskompensator aufweist, der durch die Verbrennungsgase der Ladung zum Austreiben (4) gezündet wird, die die erste Kammer (7) füllen.
