Lead fluoride acts as a densifying and stabilizing ingredient for a propent.

Densifying and stabilizing ingredient

A multi-component propellant charge is disclosed wherein one component is energetic high-strength composite resin, which is plasticized by an energetic plasticizer and supports the other components during the high-acceleration stage of the propellant's performance.

Multi-component propellant charges

A method for manufacturing crosslinked double base propellants which incls compounding the propellant with no more than 0.1 weight percent of a crosslinking catalyst, partially curing the propellant by a mild heat prior to extrusion until the energetic binder is plasticized but not crosslinked, and extruding the propellant in a ram extruder at a temperature from 120.degree. F. to 150.degree. F. before the crosslinking mechanism has become too advanced for extrusion.

Method for high strength double base solventless gun propellant

A double base propellant having plasticizer and ballistic modifiers unifoy dispersed therein is formed by using high speed, high shear techniques. The method of uniformly incorporating plasticizers and ballistic modifiers in a solventless process for preparing nitrocellulose is accomplished by forming a slurry of nitrocellulose under high shear, high speed mixing, adding the plasticizers and modifiers thereto and recovering the propellant.

Double-base nitrocellulose propellant

Solids loaded, extrudable, solventless, double-base propellants are formued by combining liquid plasticizers, solid binders, a high percentage of solid oxidizers, and fillers to yield propellants having high densities and capable of delivering high specific impulse.

Method for making extruded, solventless, composite-modified double base

Ballistic modifiers of up to one micron in size are slurried and mixed with high impulse propellant slurry in order to produce a high impulse propellant having a plateau or mesa burning characteristic.

Incorporating ballistic modifiers in slurry cast double base containing

High shear treatment of a slurry of explosive particles breaks up agglomees of the explosive particle, forms a stable slurry of fine explosive particles, and tests the slurry for water content.

Process for forming a pourable plastisol nitrocellulose slurry

A method for extruding solventless gun powder comprising working and refong said gun powder by extruding through a plurality of holes in at least two plates prior to final extrusion through a die whereby said solventless gun powder has improved tensile strength.
