Definitions

  • the present invention relates to a highly explosive blast active charge.
  • HE blast charges such as WO 2004/069771 and EP 1584610 A2 are known, typically consist of mixtures of explosives with metallic fuels such as boron, silicon, aluminum, titanium, zirconium, magnesium or mixtures or metal-rich compounds or alloys of these metals.
  • blast active charge which addresses the above-mentioned problems with conventional blast active charges avoids.
  • the blast active charge should achieve higher performance, ie a faster and as complete as possible burnout in enclosed spaces.
  • the blast active charge proposed according to the present invention consists of red phosphorus or a red phosphorus-containing compound, an explosive and a binder.
  • the blast charge is thus highly explosive, burns faster and more complete than conventional metal-based blast charges and achieves a very high pressure volume work.
  • the binder of the blast active charge may optionally be an inert binder or an explosive, such as TNT or TATB.
  • the molecular P / O ratio of the blast active charge can be both ⁇ 2/5 and ⁇ 2/5.
  • the present invention solves the above-described problems of conventional metal-based blast reactor charges through the use of red phosphorus.
  • red phosphorus is ignited under atmospheric pressure, a slow burn-off occurs in the range of 0.1 mm / s.
  • oxygen-based pyrotechnic compositions based on red phosphorus deliver burn rates of 1-2 mm / s. If such sentences are included, an explosive burn-up takes place after ignition.
  • HMX High Melting Explosive
  • HTPB hydroxyl-terminated poly-butadiene
  • RP red phosphorus
  • the invention is not limited only to blast active charges with the above ternary system HMX / HTPB / RP.
  • an explosive such as TNT or TATB may be used in place of the non-explosive and low-inflammatory HTPB.
  • the molecular P / O ratio of the blast active charge may be both ⁇ 2/5 and ⁇ 2/5.
  • red phosphorus or red phosphorus-containing compounds in the blast active charge of the invention causes a high pressure exponent n in the aforementioned Dahlle's Law, resulting in accelerated burnout in confined spaces.
  • the resulting oxide is highly volatile in this case (e.g., from about 250 ° C), resulting in a complete or at least nearly complete reaction of the active charge and at the same time contributing to pressure-volume work.
  • blast active charge requires a smaller amount of expensive nitramines such as HMX and the like than conventional systems.

Claims (5)

  1. Charge active à effet de souffle, constituée de l'explosif octogène (HMX), d'un liant et de phosphore rouge (RP), le phosphore rouge étant disposé pour provoquer un exposant de pression élevé et donc une combustion totale accélérée dans des espaces clos, une haute volatilité de l'oxyde résultant apportant une contribution au travail pression-volume
  2. Charge active à effet de souffle selon la revendication 1, caractérisée en ce que le liant est du polybutadiène à terminaison hydroxy (HTPB).
  3. Charge active à effet de souffle selon la revendication 2, consistant en l'explosif octogène (HMX), le liant polybutadiène à terminaison hydroxy (HTPB) et en phosphore rouge (RP) en un rapport de mélange HMX/HTPB/RP égal à 68:12:20.
  4. Charge active à effet de souffle selon la revendication 1, caractérisée en ce que le liant est un explosif.
  5. Charge active à effet de souffle selon la revendication 4, caractérisée en ce que le liant est le TNT ou le TATB.
