Design of Magnetic Sensors for Obtaining an Environmental Safety Signature
Abstract
The safing and arming systems of most artillery projectiles in common use have a signature provided by setback forces arising from the acceleration of the projectile upon firing. To obviate the possibility of accidental arming through dropping or jolting of a round, a second signature is desirable. In fin-stabilized rounds, since spin is absent, a means must be found for supplying the second arming signature. To obtain such a signature it was decided to employ two magnetic transducers positioned near the surface of the projectile. These transducers sense a change in magnetic flux when the projectile leaves the permeable gun barrel, and emit an electrical pulse that activates a piston motor in the arming mechanism which in turn completes the arming process.
