Miniature Solid State ARM Safe Device, Phase IV

摘要

The report covers pertinent facts, figures, and data pertaining to the research and development effort expended on Phase IV of the Miniature Solid State Arm Safe Device. Investigations were primarily concerned with improving the pillbox transducer, improving some of the characteristics of the Miniature Solid State Arm Safe Device itself, and extending the previous Device to that of a predetermined application. Specific accomplishments are as follows: the properties of the transducers were considerably improved; the arming time was extended to 150 seconds; the transducer was isolated from the transistorized integrating circuits; the bias balancing of the circuits are such that the Device can remain unshorted for at least 5 minutes before the fire command without adverse effects; the presetters were calibrated and manually controlled to within plus or minus 3 percent accuracy; all presetters were approximately 1 cubic inch in volume; the size of the two Miniature Devices was 2 inches in diameter and 2 inches in height and 0.2 cubic inch for the subminiature model; the current drain from the 6 volt supply was less than 250 milliamperes in all Devices; all environmental specifications were met.
