Abstract: Embodiments employ venting features and damping components both inside and concentric to a fuzewell to improve munition fuze survivability. Damping components are selected based on their densities and stiffness properties. A shock damping liner with longitudinal grooves is affixed to an inner surface of the fuzewell and envelops the fuze. At least one shock damping collar constrains and attenuates shack experienced by the fuze. A shock damping ring is concentric about the outer surface of the fuzewell and attenuates shock, between the outermost munition system layer (the casing) and the fuzewell. Longitudinal vents in the fuzewell wall and radial apertures oriented transverse to the longitudinal vents are used for off-gassing. The venting and component orientation combination provides increased damping, resulting in impedance mismatches across multiple interface surfaces in the munition, which reduces shock vibrational pressures and stresses transferred to the fuze.

Abstract: Embodiments employ venting features and damping components both inside and concentric to a fuzewell to improve munition fuze survivability. Damping components are selected based on their densities, stiffness properties, and material strengths. A shock damping liner with longitudinal grooves is affixed to an inner surface of the fuzewell and envelops the fuze. A biased equivalent strength threaded shock damping ring is concentric about the outer surface of the fuzewell and attenuates shock between the outermost munition system layer (a munition case) and the fuzewell. The damping components' materials, orientations, and structural geometries provide increased damping, resulting in impedance mismatches across multiple interface surfaces in the munition, which reduces shock vibrational pressures and stresses transferred to the fuze.
