ABSTRACT:
A caseless propellant charge structure and sensitizer structure for safe ignition and cleaner gas generation. The sensitizer structure is comprised of a sensitizer material which is encapsulated in a protective binder material. The protective binder layer is broken during desired ignition in the combustion chamber. Meanwhile the propellant structure comprises an oxidizer rich layer which also contains fuel and a propellant layer. The oxidizer rich layer is adjacent the sensitizer structure in the strip assembly. The oxidizer rich layer allows ignition while foregoing the need for high concentration of oxidizer throughout the propellant structure thus reducing the mass of solids generated from the oxidizer combustion.
