Definitions

the present invention relates to a highly explosive blast active charge.
HE blast energy charges 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.
