  • Tactical wire-cutter system for helicopters
    Patent number: 4407467
    Abstract: A tactical wire-cutting system for helicopters includes a forwardly extending probe having a plurality of explosive cutting charges disposed along the probe. The probe is inclined with respect to the vertical as defined by the normal helicopter trim during flight such that a suspended cable will come into successive contact with the explosive cutting charges. The charges are designed to catch and hold the cable until detonation and thereafter to allow the cable to proceed to the next successfully positioned charge if unsevered.
