ABSTRACT:
The present invention provides a propellant for electrothermal-chemical guns comprising a dispersion of one or more energetic solids in an energetic liquid phase. The energetic solid is preferably a nitramine such as cyclotrimethylenetrinitramine (RDX) and the energetic liquid component is preferably a homogeneous liquid that is either aqueous or non-aqueous. Aqueous liquid phases suitable for use in the present invention include concentrated solutions containing at least one nitrate salt. Non-aqueous liquid phases suitable for use include those that contain nitrate ester, nitramine, nitro or azido compounds or mixtures thereof.
These propellants provide a high level of energy density because of the use of energetic ingredients and the high loading density allowed with a liquid propellant. The presence of a dispersed solid phase within the continuous liquid phase also permits control of the burning behavior of the propellant by variation of the interfacial area between phases.
