Definitions

  • the invention relates to a method for increasing the pressure of a composite charge containing at least one explosive, an inert or energetic binder and a reactive metal powder.
  • Modern conventional and insensitive explosive charges contain mainly explosives such as RDX (hexogen) or HMX (octogen), mixed with plastic binders such as HTPB (hydroxyl-terminated polybutadiene).
  • RDX is less sensitive than HMX and is often used for pressure-boosted explosive charges, for example, if high shock-wave immunity is required.
  • HMX is somewhat more powerful in terms of accelerating metal builds or sheaths, and is more likely to be used when the focus is on splitter performance rather than sensitivity.
  • blast enhancement can be achieved by admixing reactive metal powders (e.g., aluminum, boron, silicon, magnesium, etc.).
  • reactive metal powders e.g., aluminum, boron, silicon, magnesium, etc.
  • the shape and size of the metal particles play an important role in the blast increase.
  • Such charges are then referred to as “composite charge”.
  • Other ingredients such as plasticizers, adhesion promoters, etc. are added as needed.
  • formulation of the charge is then referred to as formulation of the charge.
  • the procedure for the above-mentioned optimization of the blast performance is such that formulations are produced (eg RDX / Al / HTPB) by varying the amount of ingredients in different proportions and then testing these cargoes for their performance in mostly large series of experiments. This procedure is time-consuming and cost-intensive.
  • the DE 40 02 157 A1 describes various examples of polymer-bound explosives, aiming at optimizing the mechanical properties.
  • this invention has for its object to provide a method for maximizing the blast performance of a charge, in particular for bunker control, which has the formulation of an explosive charge with optimized blast performance in a short time to result.
  • This object is achieved by first determining the proportion by weight of the explosive depending on the intended application, then the proportion by weight of the metal powder used as fuel according to the proviso is determined, and that each individual metal particle is completely oxidized with the entrained oxygen, wherein the minimum size of the metal particles is determined depending on the minimum time within which each metal particle is oxidized.
  • phase I and II so the oxidation and thus the energy can be accomplished only by the entrained oxygen. Only in the third phase III it comes to mixing with atmospheric oxygen and thus to afterburning. Almost all military explosive charges have an oxygen sub-balance, that is to complete conversion (post-combustion) they need oxygen from the air. This is especially the case if you add in addition Adds fuels such as reactive metal powder. This is exactly the method to increase the degree of reaction and thus the blast performance.
  • RDX- and HMX-containing explosive charges for example, the C and H atoms are oxidized to CO 2 and H 2 O.
  • the N atoms usually behave "neutrally” and combine to form N 2 .
  • Addition of additional metal powder (such as Al) leads to further oxidation, such as Al 2 O 3 .
  • the method according to the invention for maximizing blast performance now proceeds as follows. For a given explosive charge formulation, add stoichiometrically the same amount of fuel powder that all metal ions can be oxidized with the entrained oxygen of the charge (without atmospheric oxygen). The C atoms, H atoms, etc. are later further oxidized by atmospheric oxygen. This maximizes blast performance.
  • the aim is to optimize the blast performance of any explosive charge formulation of the above-mentioned compositions by this procedure, ie to find the local maximum in a multi-dimensional parameter space on without to have to fall back on a purely statistical, time / cost consuming procedure and at the same time be able to do without extensive test series.
  • the first step of the method involves assembling the necessary explosive charge components. Emphasis will be placed on the suitability of the optimized charge for a particular application. For example, this relates to shockwave immunity in a planned bunker fight.
  • RDX is an explosive.
  • For the other components is usually similar.
  • the second step is to optimize the blast performance.
  • you add more fuel usually in the form of reactive metal powders, such as aluminum powder.
  • the key point of the maximization method according to the invention comes into play.
  • the intrinsic oxygen balance must always be taken into account for any mixture of components.
  • the oxygen content must be stoichiometrically sized so that each metal particle is saturated during the detonation with oxygen, so it can be completely oxidized.
  • the selection of the type and condition of the metal particles takes place.
  • certain conditions must be observed by the specialist.
  • the size and shape of the particles are crucial. Rapid oxidation of all powder particles during the anaerobic phase must be possible, otherwise the maximum will not be reached. If the particles are too large, the entire particles can not burn during the detonation phase. If they are too small, the relative proportion of the surface oxide layer which is usually present is too large and energy is lost again. The minimum size thus results from the available time (in the detonation phase) within which the metal particles must be completely oxidized. In addition, too small particles would be difficult to process because of increasing viscosity due to the rapidly increasing cumulative surfaces with decreasing radius, all of which must be wetted by the binder.
  • the possible inertia of the oxidation reaction is another parameter that has to be taken into account: boron, for example, is relatively inert and requires a reaction catalyst, which can be accomplished, for example, by admixing Al powder.
  • the size of the metal particles can not be chosen arbitrarily.
  • Known charges contain aluminum particles with an average grain size of 35 ⁇ m. This has been reduced to an average value of 4 ⁇ m in the context of the preparatory work for this invention, which has proven to be particularly advantageous.
  • a further reduction in the size of the particles brings no further increase, since the combustion of the micron particles is already fast enough to be completed in the above-mentioned phase II. On the contrary, a reduction to the nanometer range causes numerous disadvantages.
  • the shock wave dissolves in the detonative phase (I and II) of the fireball, any aerobic post-reactions come too late for an increase in energy of the shock wave. If all metal powder is oxidized during this phase, maximum energy release is achieved, the maximum blast effect. If one had less metal powder in the formulation, one would "give away” oxygen to the C and H atoms and thus lose energy, since the oxidation of these atoms supplies less combustion energy. If too much metal powder had been added, these "superstoichiometric" metal ions would not be oxidized and one would not have reached the optimum point either. So there is a stoichiometric optimal mixture, in which all metal ions get their oxygen content, then the blast performance is maximum.
  • Existing metal shells of the charge can be more of a hindrance, since they must first expand radially and depending on the ductility and further nature of the metal shell more or less late tear and only then release the detonation products and bring into contact with the air. During this expansion phase However, the gases cool down. If the temperature falls below a critical temperature (for example, about 2000 K for aluminum), the chemical reactions are prevented and the afterburning stops or does not even begin.
  • a critical temperature for example, about 2000 K for aluminum
  • the procedure according to the invention for maximizing the blast power is to be applied by way of example to a charge with aluminum powder.
  • the maximum obtained was validated by a conventional statistical approach, in which long and extensive series of tests were performed which confirmed the forecast maximum for both free-field and indoor detonations.
