Abstract
The present invention relates to metal filaments for use as fuel additives for rocket propellants, explosives, and other pyrotechnic devices. Preferred filaments are those such as zirconium, niobium and titanium (and alloys thereof) which have very high heat of combustion.
Claims6
An explosive device such as a propellant comprising a normal organic propellant and oxidizer and a controlled amount of metal filaments from the group consisting of Aluminum, Zirconium, Titanium, and Niobium and alloys thereof having a predetermined substantially uniform surface to volume ratios, the metallic filament including a bi-metallic mixture of two additional metals having a high heat of solution.
A bi-metallic filament of aluminum and another metal from the group of nickel and palladium, said filament having a diameter less than 20 microns and comprising multiple thin longitudinal portions of at least one of said metals in intimate contact with the other of said metals, the radial cross-section of said thin portions being less than 3 microns.
