Abstract: An ignition device in the form of a linear member which has an internal linear propagation characteristic of a detonation, but a radial heat and gas evolution characteristic of a very fast deflagrating pyrotechnic material not accompanied by a shock or detonation wave. The device uses a central core containing an encapsulated explosive with a surrounding layer, or discrete layers, of a metal-clad pyrotechnic material that is significantly characterized by a class of compounds that are specific simple decahydrodecaborate salts containing the common anion B.sub.10 H.sub.10.sup.-2. The outer cladding materials themselves do not functionally ensure a radial deflagration; rather the specific pyrotechnic materials employed ensure a radial deflagration. There are taught specific relationships for components, and a necessary radial compaction.

Abstract: A mixed, intramolecular perchlorate salt, having a carboranyl moiety and ferrocenyl moieties, is used as a partial replacement for ammonium perchlorate to achieve ultrahigh burning rates for propellants. The perchlorate salt when incorporated into a propellant composition contributes to the oxidizer function, and in addition, since both boron and iron are present, two mechanisms for burning rate catalysis are exploited. The described compound, carboranyldiferrocenylmethyl perchlorate, obviates the need for incorporating the burning rate catalysts separately.

Abstract: Fuel-rich propellant compositions, for use in air-augmented rocket propulsion, containing a high-energy fuel component in the form of finely-divided boron, wherein the boron is present in large excess of the amount oxidizable during combustion of the propellant. A major portion of the boron is ejected, largely as free boron particles, together with the combustion products of the propellant and is burned downstream of the propellant by ram air injected into an afterburner combustion zone. The propellant additionally comprises an organic fuel binder comprising an organic polymer, and an inorganic oxidizer salt, preferably ammonium perchlorate, in an amount at least sufficient to maintain stable combustion of the propellant at desired combustion chamber pressures. The propellant compositions may additionally contain small amounts of Mg, Al, or Zr metal as ballistic or afterburner combustion modifiers.

Abstract: Methyltricarboranylmethyl perchlorate is disclosed along with its synthesis nd its use in a solid composite propellant. Three carboranyl groups and a perchlorate group are contained in the intramolecular perchlorate salt, methyltricarboranylmethyl perchlorate, which is used as a partial replacement for ammonium perchlorate and as a replacement for liquid carborane catalyst-plasticizer compounds to achieve ultrahigh burning rates for propellants. The perchlorate salt when incorporated into a propellant composition contributes to the oxidizer function, and in addition, since three carboranyl groups are present in each molecule of the salt, the burning rate catalysis function is accomplished without having to incorporate separate burning rate catalysts.
