Abstract
Embodiments are directed cook-off mitigation systems. As assembled, a munition fuzewell is torqued into the aft end of a munition. The fuzewell is hollow and has an inner and an outer surface. The hollow fuzewell is configured to release during cook-off. Release is assisted by employing a biased equivalent strength threaded release ring concentric about the fuzewell. The biased equivalent strength threaded release ring has a threaded inner surface and a threaded outer surface. The biased equivalent strength threaded release ring's threaded inner surface threadingly-engages with threads on the fuzewell's outer surface. A munition case is concentric about the biased equivalent strength threaded release ring.
Claims10
A cook-off mitigation system, comprising:
- a hollow fuzewell having a proximal end, a distal end, an inner surface, an outer surface, and a hollow fuzewell wall defined by said inner surface and said outer surface, said hollow fuzewell centered about a central longitudinal axis, said inner surface defining a fuzewell inner envelope having a first inner portion, a second inner portion, and a third inner portion, wherein said first inner portion is located at said proximal end, said third inner portion is located at said distal end, wherein said second inner portion separating said first and third inner portions;
- wherein said outer surface of said hollow fuzewell having a first outer portion and a second outer portion, said first outer portion corresponding to said proximal end, said second outer portion corresponding to said distal end, said first and second outer portions separated by a flared region, wherein said outer surface of said hollow fuzewell is a threaded outer surface along said second outer portion;
- a fuzewell liner affixed to said second inner portion, said fuzewell liner having a plurality of longitudinal grooves parallel to said central longitudinal axis;
- a biased equivalent strength threaded (BEST) release ring concentric about said hollow fuzewell, wherein said BEST release ring has a threaded inner surface and a threaded outer surface, and a BEST release ring wall defined by said threaded inner surface and said threaded outer surface;
- and
- a munition case concentric about said BEST release ring, said munition case configured to house a main fill energetic.
