Definitions
- the invention relates to a fire mass according to the preamble of patent claim 1 and a projectile according to claim 5 or 6.
- Such fire masses are used as splinter fire ammunition in a projectile body or warhead together with a explosive explosive as well as in armor-piercing projectiles that contain no explosives. Due to the detonative or mechanical fragmentation of the projectile or warhead in or near the target, apart from the splinters, fast-flying, autonomously burning particles of fire mass are formed. This results in a spatially and temporally strong fire effect.
- 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. Based on the prior art that the use of fluorinated binders supports the formation of the tetrafluoride of the corresponding metal and strives to extend the firing time with metals in the form of coarse-grained, porous, spongy particles with a particle size of 0.05-8 mm this solution to use metal powder with an average particle size of 15-50 microns.
- 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 the blast effect and an extension of the flame life from 1 ms to 15 ms. This increases the ignition probability for combustible material.
- 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 invention has as its object to show a further fire mass, which has a sufficiently high flame life.
- Claims 5 and 6 relate to the use of the fire mass in a projectile.
- the invention is based on the knowledge gained in investigations that with a corresponding particle size distribution of the preferably spherical metal powder in the range of 50-250 .mu.m only a proportion of the binder in the fire mass even less than 1 mass% is needed.
- the binder can be used in the smallest possible concentration, which still ensures sufficient compressibility and fixation of the fire mass.
- this distribution has also shown the best results in practice.
- the use of spherical metal powders, in particular zirconium metal powder, 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. Volumetric means to make the powder slippery by using coarse granules with ultrafine powder and at a given temperature.
- a good organic binder is bakelite®, which is incorporated in a microenvironment and thus supports volumetric dosing.
- an organic binder preferably halogen-free, is also incorporated in this fire mass.
- This is, as already stated, preferably a thermoset or thermoplastic micronized organic binder.
- the fire mass is inert in the projectile inert, its function in the target is developed by means of chemical reaction with atmospheric oxygen (air-breathing system with thermobaric reaction as non ideal high blast explosives).
- the fixation of the fire mass in the projectile or warhead is carried out by pressing and subsequent heat treatment to activate the thermoset crosslinking or melting of the thermoplastic binder.
- metal powders are titanium or hafnium. These types of metal powders are not made from the reaction of the individual basic substances themselves, but from starting materials processed into bars. Thus, the zirconium powder with an average grain size is not obtained from zircon itself, but from a zirconium rod.
