Nanotubular structures of high energy materials are used in high energy compositions, such as propellants.

Burn rate nanotube modifiers

A method for making high energy compositions, such as propellants, explosives, pyrotechnics or the like, including a solid metal particulate fuel dispersed in a cured binder matrix. The compositions are formed with ingredients including a particulate metal fuel such as boron, binder polymer (such as GAP polyol), binder plasticizer, and a curing agent containing isocyanate. The improved method includes pre-reacting the particulate metal fuel with an amount of isocyanate, which acts as a curative to neutralize residual acid. The particulate metal fuel/isocyanate from the pre-curing step is mixed together with the binder polymer, binder plasticizer, and remaining curing agent to form the solid propellant. The initial neutralization of the metal fuel avoids gassing and improves the mechanical properties of the propellant yield.

A thermobaric explosive composition is provided that includes coated fuel particle, a nitramine, and binder. The coated fuel particles preferably have a magnesium core and an aluminum coating. Upon detonation, the nitramine disperses the coated fuel particles over a blast area during a first overpressure stage. The aluminum coating of the fuel particles has a thickness selected to provide an amount of aluminum that is stoichiometrically less than an amount of ambient-air oxygen available in the blast area for aerobic combustion with the aluminum during the first overpressure stage. Once exposed, the magnesium cores may combust to increase the impulse generated in the first overpressure stage. Also provided are articles of manufacture and related methods.

An emulsion explosive including a discontinuous phase dispersed in a liquid fuel continuous phase and is provided. The discontinuous phase contains a liquid oxidizer other than an inorganic oxidizer salt. Also provided are articles of manufacture containing the emulsion explosive.

Emulsion explosive

An infrared emitting device produces a certain heat emission. The device has a heat source for generating a specific amount of heat for heating inert material to a given temperature and expelling this heated material to form a cloud. The heated inert material produces an infrared emission for anti-missile operations.

Device and method for producing an infrared emission at a given wavelength

A countermeasure for luring an incoming hostile missile away from a vehicle is provided. The countermeasure includes a housing, an infrared-emission body containing a sublimation compound in a solid state, a heating source for converting the sublimation compound into a vapor state, and a case containing the infrared-emission body. The case includes an outlet for discharging the sublimation compound in the vapor state into the atmosphere, where the sublimation compound is returned to the solid state in the form of a discrete cloud of particles. Also provided is a method for using the countermeasure, for example, to evade a hostile missile.

A system for deploying an aircraft emergency evacuation slide or other inflatable device utilizes an inflation gas that is stored in a partially liquified state. The inflation gas includes a gaseous compound, preferably nitrous oxide, that is capable of undergoing an exothermic thermal decomposition, which gives off heat and produces a greater number moles of inflation gas than the number of moles of gas stored. The increase in moles of gas allows a greater inflation volume for a given weight of stored gas, while the exothermic decomposition produces additional heat that offsets, to some extent, the endothermic boiling and expansion of the liquified stored gas.

A dual stage hybrid inflation device includes a pressure switch that prevents the second stage pyrotechnic gas generator from being initiated when the additional heat and gas would overpressurize the first stage pressure vessel. As the pressurized gas stored in the first stage pressure vessel escapes the first stage pressure vessel, the pressure in the first stage pressure vessel drops. If the pressure in the first stage pressure vessel drops below the threshold pressure of the pressure switch, the pressure switch closes allowing the voltage signal to reach the pyrotechnic gas generator thereby initiating the second stage gas source. In an alternative embodiment, the pressure transducer is replaced by a pressure transducer or a temperature transducer and timing circuit. By delaying the initiation of the second stage gas source until after the pressure in the first stage pressure vessel has dropped below the threshold level, the appropriate augmentation of the compressed first stage gas can be realized without the necessity of designing the first stage pressure vessel to withstand initiation of the pyrotechnic gas generator under maximum inflation pressure conditions.

Temperature compensating inflation device

A high temperature combination delay element and ignition composition contains a polymeric silicone component, an oxidizer component and a high temperature metal component.

The invention is a dolly on wheels for lifting and moving manhole covers. The dolly has a pivotal sleeve into which a lifting bar fastens and a bottom plate with a crooked tail on its bottom side. The lifting bar has a pointed end which is used in conjunction with the bottom plate to lift small manhole covers and a finger end which is used in conjunction with the bottom plate and tail to lift large manhole covers.
