Abstract
A multi-mode fuze includes first and second microprocessors, the first microprocessor being connected to a resistor/capacitor oscillator and the second microprocessor being connected to a quartz crystal oscillator, the first and second microprocessors being connected to each other, the second microprocessor being operable to time calibrate the first microprocessor; a safe and arm device connected to the first microprocessor; power storage capacitors connected to the first microprocessor; a nose mounted impact switch connected to the first microprocessor; at least one impact delay circuit connected to the first microprocessor; and at least one acceleration switch connected to the first microprocessor.
Claims15
A multi-mode fuze settable in the bore of a gun, comprising:
- a first microprocessor is settable in a plurality of modes to initiate a fire signal, and a second microprocessor, the first microprocessor being connected to a resistor/capacitor (RC) clocked oscillator and the second microprocessor being connected to a quartz crystal clocked oscillator, the first and second microprocessors being connected to each other, the second microprocessor being operable to time calibrate the first microprocessor just prior to firing of the gun.
