Abstract
A plurality of radio frequency shielded electrical break wire sensors for a issile fuze circuit are peripherally positioned on the circumferential outer surface of a warhead body. A first wire sensor provides an electrical indication of contact of the warhead outer surface with a target structure and initiation of the fuze electronics in response thereto. A second printed wire sensor is operatively positioned underneath the first sensor to provide an electrical indication of an impending break-up of the warhead body structure and initiation of the missile fuze.
Claims4
A target sensing device for initiating the warhead of a projectile which comprises:
- a warhead body section having a pair of peripheral band surfaces thereon, an annular groove disposed intermediate said pair of band surfaces, and a longitudinal slot disposed through one of said pair of band surfaces and communicating with said annular groove;
- a fluorocarbon coating disposed on said pair of band surfaces;
- a hard target impact sensor means, fixedly disposed in said annular groove and in said longitudinal slot, for indicating breakup of said warhead body when said warhead body penetrates a target;
- a target contact sensor means, operatively disposed on said fluorocarbon coating and partially covering said hard target impact sensor means, for indicating contact with said target;
- and
- shield means fixedly disposed over said target contact sensor means and said hard target impact sensor means for isolating said target contact sensor means and said hard target impact sensor means from radio frequency radiations.
