Abstract
A system permitting VT (Variable Time) fuze setting information to be transmitted thereto from a remote fire control source via a microwave link when the fuze is chambered in a gun barrel prior to the firing of an artillery shell to which the fuze is affixed. Sufficient microwave power is initially transmitted to the fuze by means of the barrel acting as a microwave transmission line wherein the microwave power received is converted to a DC voltage which is stored and used to bias the fuze circuitry which subsequently receives binary detonating data AM modulated on a microwave carrier.
Claims10
A system for supplying setting information from a fire control system to an electronic fuze mounted on a projectile chambered in a gun barrel prior to setback comprising in combination:
- a source of microwave energy operated by said fire control system, said source generating microwave signals adapted to supply both DC power and fuze setting data to said fuze;
- and
- means coupling said microwave signals into said gun barrel intermediate the fuze and the muzzle of the barrel, said barrel being utilized as a microwave transmission line thereby.
A system for supplying setting information from a fire control system to an electronic fuze mounted on a projectile chambered in a gun barrel prior to setback comprising in combination:
- a source of RF energy;
- means coupled to said source of RF energy for initiating a burst of CW energy upon triggering projectile firing means;
- means coupled to said source of RF energy for modulating said source with detonating information, and providing a modulated RF signal subsequent to said burst of CW energy;
- means coupling said burst of CW energy and said modulated RF signal into said gun barrel, said gun barrel thereby acting as an RF transmission line;
- first fuze circuit means responsive to said CW energy to provide an arming voltage for said fuze;
- and
- second fuze circuit means responsive to said modulated RF signal, being operable with said arming voltage to set said fuze with detonating information.
