Embodiments of the invention are directed to enhancing insensitive munitions performance. Some embodiments of the invention employ an outgassing pad having unique geometrical configurations and positioning. Other embodiments rely on using thermally-releasable components to foster billet expulsion. Additional embodiments combine both aspects into an entire cook-off mitigation system.

1. A cook-off mitigation system in a munition, comprising: a munition casing having at least one interior compartment, a nose end, and a tail end;wherein said at least one interior compartment is configured to house at least one explosive fill;an uncanistered outgassing pad inside said at least one
1. A cook-off mitigation system in a munition, comprising: a munition casing having at least one interior compartment, a nose end, and a tail end;wherein said at least one interior compartment is configured to house at least one explosive fill;an uncanistered outgassing pad inside said at least one interior compartment, wherein said uncanistered outgassing pad is positioned at said nose end;a charging well cavity penetrating said munition casing, said charging well cavity having a top end and a bottom end;a fuzewell attached to said tail end of said munition casing;a munition fuze housed inside of and attached to said fuzewell;a charging well component attached inside said charging well cavity, said charging well component electrically-connected to said fuze, said charging well component attached to said munition casing by a plurality of fasteners; anda releasable tail closure mechanism attached to said tail end of said munition casing, said releasable tail closure mechanism configured to contain said at least one explosive fill in said interior compartment. 2. The system according to claim 1, wherein said munition casing is steel. 3. The system according to claim 1, said uncanistered outgassing pad, further comprising: an outgassing agent having at least two sides that are diametrically-opposed to one another;wherein at least one of said at least two sides is adjacent to said nose end;wherein the other of said at least two sides is adjacent to said at least one explosive fill. 4. The system according to claim 3, wherein said outgassing agent has surface contours having a sigmoid shape. 5. The system according to claim 3, wherein said outgassing agent is a powder and binder mix. 6. The system according to claim 3, wherein said powder is calcium formate. 7. The system according to claim 1, wherein said munition casing has an interior protective liner separating said munition casing, said charging well cavity, and said releasable tail closure mechanism from said at least one explosive fill. 8. The system according to claim 1, wherein said bottom end is a structural material selected from the group of structural materials consisting of steel, aluminum, and plastic. 9. The system according to claim 1, wherein each fastener in said plurality of fasteners attach said charging well component to said bottom end. 10. The system according to claim 1, wherein said plurality of fasteners are plastic. 11. The system according to claim 1, wherein a dedicated eutectic device is concentric about a corresponding fastener in said plurality of fasteners, wherein each of said dedicated eutectic device secures said bottom end to each corresponding fastener in said plurality of fasteners. 12. The system according to claim 1, said releasable tail closure mechanism, further comprising: a base plug concentric about said fuzewell and attached to said munition casing; anda releasable base plate concentric about said fuzewell, said releasable base plate attached to said base plug and said munition casing. 13. The system according to claim 12, wherein said releasable base plate is a eutectic device.
