The inclusion in a double base propellant of a ballistic modifier selected rom the class consisting of copper, lead, tin, and bismuth chelates of a dihydroxybenzophenone or alkoxyhydroxyphenzophenone.

Doublebase ballistic modifiers

The addition of monobasic cupric .beta.-resorcylate to a double base propant plasticized by only nitrate esters having primary nitroxy groups in order to obtain a plateau burning characteristic.

Plateau propellant compositions

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

Double-base propellant compositions of the plateau and/or mesa type which e comprised of ballistic modifiers of lead and copper salts of acetamidobenzoic acids, acetamidosalicylic acids, and resorcylic acids.
