Definitions

• the invention relates in particular to rotationally stabilized subprojectiles of a projectile, which comprise an energetic content.
• Known splinter firing munitions contain mixtures of highly explosive explosives such as hexogen, octogen, trotyl and aluminum powder.
• DE 29 01 517 describes a fire mass with an organic binder and a metal sponge, e.g. zirconium or hafnium, polytetrafluoroethylene being used as binder at a level of from 2 to 15% by mass.
• a metal sponge e.g. zirconium or hafnium, polytetrafluoroethylene being used as binder at a level of from 2 to 15% by mass.
• the company's EP 0 051 324 B1 discloses a generic fire mass which uses an organic binder and metal particles.
• this solution proposes to use metal powder with an average grain size of 15-50 ⁇ m.
• the binder an organic halogen-free binder, a polyvinyl acetate, has a content of less than 2% by mass. This still ensures sufficient compressibility of the metal powder.
• the metal additive itself causes an increase in blast effect and an extension of the flame life from 1 ms to 15 ms. This increases the ignition probability for combustible material.
• spherical metal powder in the range of 50-250 ⁇ m.
• the binder can be used in the smallest possible concentration, which still ensures sufficient compressibility and fixation of the fire mass.
• spherical metal powders in particular zirconium metal powders, with a higher surface area allows the binder to be applied dry to the surface of the metal powder, which increases the flowability and allows volumetric metering.
• EP 1 286 129 A1 discloses another fire rate for a wing-stabilized balancing bullet, which has a good effect despite a relatively small volume and a low mass.
• the fire rate is ignited by the shock waves that occur when impacting a target.
• a titanium sponge is used and as binder an epoxy or polyester resin.
• the particle size range of the titanium sponge is 450 ⁇ m, with 30% having a particle size greater and 70% less than 450 ⁇ m.
• the object of the invention is to achieve a fire effect that is more effective, especially in the target, or to react with energetic target material.
• the invention is based on the idea of incorporating the fire mass or the energetic component of a projectile into the subprojectiles.
• the subprojectiles are made of ductile heavy metal or hard metal in a known manner in a cylinder, ball or cube shape with a recess with or without predetermined breaking points. Thereafter, the introduction and compression takes place, preferably by machine, the energetic component and, if provided, the metered addition of a pressure-sensitive ignition charge with subsequent pressing.
• the release of subprojectiles can be done in a known manner.
• the energetic content of the sub-projectile is activated by:
• the energetic content of the subprojectiles includes a pyrotechnic, such as Thermite, Pyrofuze (see http://www.sigmundcohn.com/german/pyrofuse.html, DE 21 30 367 A1) or Coruscative (US 3,135,205) with thermobaric reactions.
• a pyrotechnic such as Thermite, Pyrofuze (see http://www.sigmundcohn.com/german/pyrofuse.html, DE 21 30 367 A1) or Coruscative (US 3,135,205) with thermobaric reactions.
• Mg Al 1 Si - Bariumperoxid- systems are used, such as the company's own YIS 506.
• the subprojectiles are preferably rotationally stabilized.
• the rotation stabilization allows an oriented impact of the sub-projectile (s) in the target. (The rotation is about 1000 Hz at the mouth of the pipe).
• the orientation - cavity with energetic content can be done on the front or rear side in the subprojectile.
• FIG. 1a is a sectional view A-A a first variant of the shape of the sub-projectile of FIG. 1st
• this subprojectile 1 has a bore or recess 5 having hard metal and / or heavy metal body 2 for receiving an energetic component 3.
• a firing 4 preferably ends flush with the housing body 2.
• the energetic component 3 may be a powder, a rod material or the like.
• a zirconium powder is precompressed in the projectile bore 5 and the firing 4 is metered in and compressed at about 400 MPa.
• the ratio set here can be 10/1.
• Pyrofuze is cut into, for example, 8 mm long parts and inserted into the projectile bore 5.
• the priming 4 is metered in and pressed.
• Sufficient is also here a ratio of 10/1, wherein it has proved to be advantageous if a ratio of 13/1 is established.
• zirconium sponge is used, as in a third embodiment, this is also compressed in the projectile bore 5 and the priming 4 is added. Also recommended is a ratio of 10/1.
• the subprojectiles are pressed only with the corresponding energetic materials (zirconium powder, zirconium sponge, pyrofuse, coruscative, etc.) without priming in the projectile bore with about 400 MPa.
• the mass of the energetic content can be increased according to the proportion of lacking motivation.
• the volume of energetic material injected into the subprojectiles is in the range of approximately 5-20% of the projectile volume.
• the sub-projectiles 1 of the non-illustrated carrier projectile are released, for example by a programmed ignition.
• spontaneous ignition or by the pressure sensitive Anakiung 4 which is ignited by air friction, ignition in the carrier projectile together with a discharge charge or at the latest when hitting the target, ignites the pyrotechnic, energetic component 3 in Sub captivatingil 1.
• This has in addition to its conventional function now also Fire mass or a chemically reactive with the target material reactive material in the target.
• the subprojectiles may be cylindrical or spherical or may also have a polygonal cross section.
