Abstract:

The primer is an instantaneous electric initiator developed by the Naval Ordnance Laboratory for use in the Mk 255 Mod 0 bomb fuze. Primers were subjected to rough handling and surveillance tests to compare their characteristics under adverse conditions with those under normal conditions. Preliminary non-destructive tests visual inspection, x-ray, and electrical resistance measurements, revealed no defects in the lot of 395 primers. Rough handling and surveillance tests had no significant effect on functioning reliability or output, but surveillance tended to widen the range of the input sensitivity levels. The thermal parameters of the bridge wire of the primer were determined. They are expected to be useful for predicting the sensitivity of the primer to electro-magnetic radiation. The subject primer proved to be outstanding with respect to over-all reliability and to withstanding extreme environmental conditioning. Author
