Definitions

  • the invention relates to firearms intended for firing ammunition without a holster and to ammunition of this type adapted for such weapons.
  • firearm is meant a weapon comprising at least one tube by which a projectile is fired and a device for triggering this firing.
  • the tube to which reference is made constitutes the part of the weapon in which the ammunition is fired.
  • the tube can constitute the entire barrel of the weapon or only the rear part of this barrel; in the latter case the weapon may include a mechanism with several tubes (of the barrel type) capable of parading before a barrel.
  • a conventional ammunition "with case” essentially consists of a projectile, a case housing a charge of powder, a priming device carried by this case, and means for securing between the projectile and the case (means for securing generally produced by crimping the case on the projectile).
  • Such ammunition "with cases” has a certain number of drawbacks constituted by their cost price (the case comes in for a percentage of 35% of the total cost price) and by the obligation to extract the case from the weapon once fired. It has therefore been proposed to produce ammunition "without a case” which is essentially constituted by a projectile and a charge of powder joined together to form a monobloc assembly which can be handled and stored, priming means being provided for igniting the said powder charge.
  • the temporary attachment means between the projectile and its case are active until the pressure in the case, after triggering of the initiation device and combustion of the powder charge reaches a value P C corresponding to the force to be exerted on the projectile to break the temporary securing means, detach it from the holster, and propel it into the barrel of the weapon.
  • a value P C corresponding to the force to be exerted on the projectile to break the temporary securing means, detach it from the holster, and propel it into the barrel of the weapon.
  • this pressure P C is determined as a function of the temporary securing means ( generally crimping the case on the projectile) that can be used.
  • the pressure P C is approximately 1,800 bars for a projectile case connection by crimping at 50 kg.
  • the present invention therefore relates to a weapon intended to fire ammunition without a case and the ammunition adapted to this weapon.
  • the present invention aims to make such a weapon and its ammunition suitable for the characteristics and performance to be even better than those noted in the case of ammunition "with a case”, while benefiting from the advantages inherent in ammunition "without case”.
  • the weapon intended for firing ammunition without a case consisting of a projectile provided with a powder charge comprises at least one tube having an open end and a bottom, opposite said open end, and a device for triggering of the shot, capable of causing the powder charge to ignite by means of priming means, and it is characterized in that said bottom is equipped with temporary retaining means cooperating with the above projectile, these temporary retention means being arranged to cease to be active as soon as the pressure developed in the bottom of the tube reaches a value P M which can be optimized as a function of the caliber of the projectile, the weight of the projectile, the constitution of the weapon tube (smooth core tube or striped core tube), and also the nature of the desired shot (short, medium or long range shot), this optimization being made possible by an appropriate determination of the temporary retention means .
  • P M which can be optimized as a function of the caliber of the projectile, the weight of the projectile, the constitution of the weapon tube (smooth core tube or striped core tube), and also the nature of the desired shot
  • these temporary retaining means consist of a conical fitting produced by force and comprising, at the bottom of the tube a female conical surface, and, at the level of the rear part of the projectile, a male conical surface, these two male and female conical surfaces having the same conicity.
  • this taper is between 2% and 6% and the axial extent of these two conical surfaces is between 0.5 times and 4 times the caliber of the projectile.
  • the ammunition consists of a projectile provided with a powder charge, and it is characterized in that its rear part has a male conical surface.
  • the taper of this male conical surface is between 2% and 6% and its axial extent is between 0.5 times and 4 times the caliber of the projectile.
  • the pressure P M will be approximately 2,300 bar for temporary restraining means providing a restraining effect of 300 kg.
  • the invention makes it possible to produce many types of weapons as regards the constitution of their tube: - weapons with smooth tube and smooth projectile, - weapons with striped tube and smooth projectile, - weapons with rifled tube and rifled projectile.
  • the invention also makes it possible to produce many types of weapons as regards the constitution of their ammunition supply system: - one-shot weapons, - repeating weapons (barrel weapons, multiple barrel weapons), - magazine weapons, - semi-automatic weapons (shot by blow), or automatic (fire in bursts, controlled or continuous).
  • the invention also makes it possible to produce weapons comprising one or more preloaded tubes which can be replaced after firing: in the case of a weapon with several tubes, these can be arranged in barrels.
  • the projectile can, advantageously in the latter case, include a jacket made of metallic material reinforcing the resistance of the tube at least at the level of the temporary retaining means.
  • the invention consists, apart from the various arrangements which have just been mentioned, in certain other arrangements which are preferably used at the same time and which will be described in more detail below.
  • the weapon system according to the invention constituted by a new firearm intended for firing ammunition without a holster, and by a new ammunition of this type adapted for such a weapon, will be described below, in using specific examples shown in Figures 1 to 7.
  • the weapon itself 1 therefore comprises at least one tube 2 by which a projectile is fired and a device for triggering this firing, generally designated by the reference numeral 3.
  • the barrel 2 of the weapon is the part of the weapon in which the ammunition is fired.
  • the tube 2 can therefore constitute the entire barrel of the weapon (as shown in Figures 1, 2 and 4).
  • the tube 2 can also constitute only the rear part of the barrel of the weapon, and in this case the weapon can comprise a mechanism 4 with several tubes 2, of the barrel type, capable of parading in front of a barrel 5 (as shown on the Figures 5 and 6).
  • the ammunition without a case in itself is essentially constituted by a projectile 6 provided with a powder charge 7 joined together to form a monobloc assembly which can be handled and stored, priming means 8 being provided for igniting the said powder charge 7.
  • the weapon is intended to fire ammunition without a case consisting of a projectile 6 provided with a powder charge 7, said weapon comprising a tube 2 having an open end 2 a and a bottom 2 b , opposite to said open end 2 a , and a device for triggering the firing 3, capable of causing the powder charge 7 to ignite by means of initiating means 8.
  • the bottom 2 b of the tube 2 is equipped with temporary retention means 9 cooperating with the projectile 6, these temporary retaining means 9 being arranged to cease to be active as soon as the pressure developed in the bottom 2 b of the tube 2 reaches a value P M which can be optimized as a function of the caliber of the projectile, the weight of the projectile, the constitution of the weapon tube (smooth core tube or striped core tube), and also of the nature of the desired shot (short, medium or long range shot), this optimization being made possible by an appropriate determination of the retaining means temporary.
  • these temporary retaining means 9 are constituted by a conical fitting produced by force and comprising, at the bottom 2 b of the tube 2 a female conical surface 10, and, at the level of the rear part of the projectile 6, a male conical surface 11, these two male 11 and female 10 conical surfaces having the same conicity.
  • this taper is between 2% and 6% and the axial extent of these two conical surfaces is between 0.5 times and 4 times the caliber of the projectile 6.
  • the weapon 1 shown in Figures 1 and 2 has a tube 2 constituting the entire barrel of the weapon.
  • the firing trigger device 3 can be established in a conventional manner and include - a striker 21 arranged so as to be able strike the priming means 8 provided for igniting the powder charge 7 of the ammunition without case intended to be fired a striker spring 22, - an arming lever 23, a lever mechanism 24 arranged to retain the striker 21 in its armed position and release the striker 21 to let it strike the priming means 8.
  • the bottom 2 b of the tube 2 comprises the female conical surface 10 constituting a part of the temporary retaining means 9, and a bore 25 connecting this female conical surface 10 to the closed end 2 c of the tube 2.
  • a housing 26 is provided in this closed end 2 c to house the priming means 8.
  • the ammunition without case adapted for this weapon and shown in FIGS. 1 and 3 is essentially constituted by the projectile 6 proper provided with its charge of powder 7.
  • the rear part of the projectile 6 has the male conical surface 11 constituting another part of the temporary retaining means 9; in the extension of this male conical surface 11 is placed the powder charge 7 which therefore comes to lodge in the bore 25 of the tube 2.
  • the projectile 6 In front of the male conical surface 11, the projectile 6 has a cylindrical central part 27 intended to guide the projectile 6 in the tube 2, and a front part 28.
  • FIG. 4 in which the same reference numerals designate the same members as in FIGS. 1 to 3, there has been shown a weapon-munition assembly without holster in which the female conical surface 10 constituting part of the temporary retaining means 9 extends to the closed end 2 c of the tube 2, the powder charge 7 of the ammunition without a case is housed in a housing 29 formed in the projectile 6.
  • the weapon 1 shown in FIG. 5 comprises a plurality of tubes 2, arranged in a barrel 4, a mechanism with teeth 31 and with ratchet 32 actuated by the firing trigger device 3, being provided for scrolling the tubes 2 of the barrel 4 in front of the barrel 5 of the weapon.
  • a mechanism with teeth 31 and with ratchet 32 actuated by the firing trigger device 3 being provided for scrolling the tubes 2 of the barrel 4 in front of the barrel 5 of the weapon.
  • the cylindrical central part 27 of the projectile 6 can advantageously include at least two raised areas 27 a separated by a hollow area 27 b in order to improve the guidance of the projectile in the tube 2 and then in the barrel 5.
