Naval Weapons Systems


Introduction
Introduction

  • Why do we have a fuze?

    • Trigger explosive reaction

    • Keep weapon safe when not needed

  • Must be reliable and dependable

  • Safing and Arming Mechanism


Functions of the fuze
Functions of the Fuze

  • Keep weapon safe

  • Arm weapon

  • Recognize or detect target

  • Initiate detonation

  • Determine direction of detonation

    • Special Fuzes only

Target Detection Device (Four Basic Categories)

  • Impact or Contact

  • Ambient - Environmental factor

  • Timer

  • Proximity


Fuze classification by fuze operation

Proximity Fuzes:

Active

Semi-Active

Passive

Timed Fuzes

Point Detonating Fuzes

Delay Fuzes

Command Detonated Fuzes

Safing arming mechanism
Safing & Arming Mechanism

  • Safety & Arming Sensor:

    • Barrier between the TDD and the warhead

    • Can be physical or mechanical


Activation forces
Activation Forces

  • Used to arm the warhead

  • Time

  • Acceleration (Setback)

  • Deceleration (Creep)

  • Centrifugal

  • Impact


Redundancy in fuze system
Redundancy in Fuze System

  • Safety - Devices placed in series in firing path for safety.

  • Arming - Components placed in parallel in firing path for arming & firing reliability.
