High brisance metal powder explosive

A very high brisance metal powder explosive is created by including a multitude of hollow aluminum/aluminum oxide micro-particle shells deposited within a high explosive composition matrix. The interior of such micro-particle shells may contain air, nitrogen, other gases, combinations thereof, or possibly even be a vacuum. The invention might be used on warheads that are fragmentation warheads, explosively formed penetrators, air blast warheads, shaped charge jets of shaped charge warheads, or other high explosive-driven devices.

Interlaced three-dimensional printed composites and method for fabricating the same

A machine and method are presented for producing interlaced composite components. The method includes: depositing a first one or more warp filaments onto a deposition surface in a first linear direction, inserting, on top of the first one or more warp filaments, a first one or more weft filaments in a second linear direction, where the second direction is in the same plane as the first one or more warp filaments but is not parallel to the direction of the first one or more warp filaments, depositing, on top of the one or more first weft filaments, one or more second warp filaments in first linear direction, where the second one or more warp filaments are not collinear with the first one of more warp filaments, and inserting, on top of the second one or more warp filaments, a second one or more weft filaments in the second direction.

Nanoscale cocrystalline explosives

A method of manufacturing a CL-20/HMX cocrystalline explosive which is coated in a polymeric binder, so as to be useful as an explosive molding powder. The cocrystalline material having a desirable average crystal size of from about 300 nm to about 1000 nm, which crystals are intimately coated with a polymeric binder and are produced as granular agglomerates that are less than on average 5 microns in size, and which crystals are relatively easy and safe to handle, transport, store and use. The method involving spray drying a CL-20 and HMX solvent solution containing a polymeric binder to form an intermediary amorphous material—which intermediary is then heated to cocrystallize the CL-20/HMX into the desired size cocrystals and aggregates thereof—which are coated in said polymeric binder.

High density turbine and diesel fuels from tricyclic sesquiterpenes

A method for converting cedarwood oil into high density fuels including, hydrogenating cedarwood oil in the presence of at least one hydrogenation catalyst to generate hydrogenated cedarwood oil, removing the hydrogenation catalyst from the hydrogenated cedarwood oil, purifying the hydrogenated cedarwood oil to produce a first high density fuel, isomerizing the first high density fuel in the presence of at least one acid catalyst catalyst to generate a hydrocarbon mixture including adamantanes, and distilling the adamantane mixture to produce a second alkyl-adamantane high density fuel.

Voltage induced porosity in insensitive munition

A method of selectively increasing the sensitivity of an insensitive munition by inducing porosity or Joule heating in munitions assembly comprising a power source, an explosive apparatus and a fuze apparatus wherein the explosive apparatus contains a sensitized main explosive composition comprising a secondary explosive and a sensitizing agent. As a result, the otherwise insensitive munition is rendered sensitive to a propagating wave shock by approximately 10 to 25%. To this end, a voltage is applied across the main conductive explosive composition within the insensitive munition. Voltages above certain thresholds cause the decomposition of the explosive material or conductive binder, which leads to an increase in porosity, and therefore the shock sensitivity.

High density diamondoid fuels from renewable oils, triglycerides, and fatty acids

A method for making high density fuels including, heating a renewable plant oil, triglyceride, or fatty acid with at least one first acid catalyst to generate a first mixture of alkyladamantanes, increasing reaction time or adding at least one second catalysts to a first mixture of alkyladamantanes to produce a second alkyladamantane mixture, separating methyl, ethyl, propyl, and/or butyl adamantanes from a second alkyladamantane mixture to produce a third adamantane mixture to produce fuels.
