An Electric Primer-Operated Firing Pin Actuator for Large Caliber Guns.
Abstract
A device which uses an electrically fired primer (M52A3B1) to actuate the mechanical firing pin in the 155-mm, 175-mm, and 8-inch gun systems has been developed. It may be used as a direct replacement for the standard lanyard-operated firing mechanism, M35. The advantage of this device is that the standard percussion primers (M82 or similar) used in these gun systems may be actuated remotely (i.e., without the use of the lanyard), under the control of an electronic sequence timer and/or computer system. The data acquistion process is simplified because the beginning of the ignition sequence may now be time-correlated with other events. More accurate timing of ignition delays results because the initiation signal to the electric primer serves as a reference point, and the delay between application of the initiation voltage and the beginning of output from the percussion primer is less than a millisecond.
