Abstract

To hinder activation caused by unplanned stimuli, a munition may include first and second discrete, separable parts. The first and second parts may include interlocking components to prevent relative axial translation of the first and second parts. The first and second parts may be torsionally biased in opposite directions. A binder with a low melting temperature may fix the first and second parts together to prevent the torsional bias from rotating the first and second parts in the opposite directions. When the binder melts, the torsional bias may cause the first part to rotate with respect to the second part. Relative rotation of the first and second parts may allow relative axial translation of the first and second parts.
