3D shock isolation apparatus with access to one end of a body

A shock isolated fuze assembly, comprising:

• a shock isolated fuzewell apparatus, comprising:
• a fuzewell including an internal threaded portion;
• a transition member including an external threaded portion and a hollow inner portion that defines a fuzewell cavity configured for receiving said fuze;
• a layer of compliant shock isolation material positioned between said inner thread portion of said fuzewell and said external thread portion of said transition member, wherein said compliant shock isolation material encloses a front end and sidewalls of said transition member and is absent from its aft end to leave said aft end exposed;
• wherein said internal threaded portion of said fuzewell and said external threaded portion of said transition member are compliantly engaged via a gap provided by said layer of compliant shock isolation material;
• a fuze in said fuzewell cavity, and
• a retaining element for securing an aft end of said fuze to said transition member.

A projectable device, comprising:

• a penetrating shell;
• explosive or other energetic material within said shell, and
• a shock isolated fuze apparatus for igniting said explosive or other energetic material when delivered to an intended target site, wherein said shock isolated fuze apparatus comprises:
• a fuzewell including an internal threaded portion;
• a transition member including an external threaded portion and a hollow inner portion that defines a fuzewell cavity configured for receiving said fuze;
• a layer of compliant shock isolation material positioned between said inner thread portion of said fuzewell and said external thread portion of said transition member, wherein said compliant shock isolation material encloses a front end and sidewalls of said transition member and is absent from its aft end to leave said aft end exposed, and
• wherein said internal threaded portion of said fuzewell and said external threaded portion of said transition member are compliantly engaged via a gap provided by said layer of said compliant shock isolation material.
