TEST-RIG AND METHOD FOR ASSESSING THE PERFORMANCE OF BARRELLED DISRUPTORS

摘要

A test-rig (10) for assessing the performance of a liquid-jet barrelled disruptor (19) comprises a mount (20) for supporting a disruptor at a predetermined stand-off from an impact surface (16). The total linear momentum delivered by the jet at the impact surface (16) is measured using a ballistic sled (12) and the central axial impulse load of the jet is measured using a pressure gauge (18), such that a coherence metric, which characterises how focussed the jet is, can be derived. A method for assessing the performance of a liquid-jet barrelled disruptor is also described.
