INDUCTIVELY COUPLED FILTERS TO PROTECT ELECTROEXPLOSIVE DEVICES FROM ELECTROMAGNETIC HAZARDS.

Abstract

Filters are described that protect an electroexplosive device (EED) from RF energy by completely enclosing the EED within an adequately thick metallic shield that has no openings whatsoever for the entry of RF energy. Intentional firing of the EED is accomplished by inductive coupling through the shield. The measured power attenuation of these filters (30 db minimum at 200 kc) is presented for frequencies up to 10 kmc. Data for intentional firing with batteries, capacitor-discharge, and ac firing supplies are given. The performance of a filter designed specifically for the MK-1 squib and a 28-vdc firing supply is also described. (Author)
