MONITORING THE MECHANICAL OPERATION OF FUZE SAFETY-ARMING MECHANISMS
Abstract
A monitoring system is described that detects and records the mechanical operations taking place inside a safety-arming device (S-A) while it is being tested within a rotary accelerator. A ruggedized miniature crystal accelerometer, fastened to the case of the S-A, responds to internal vibrations caused by pallet clatter on the gear train, solenoid plunger bottoming, and g- weight movement. The resulting signals are converted to electrical energy and fed to an amplifier, also on the centrifuge arm, from which they are conducted through slip rings to a recorder. In addition, records are made of the time of S-A switch operations as well as the time of voltage application to the launch- latch solenoid.
