Open loop minesweeping system
View Patent ↗An open loop magnetic field minesweeping system, with a small and light weight body to be towed through seawater by a towing cable from a helicopter or other vehicle, a single sweep cable extending rearwardly a substantial distance from the body with a first electrode in cable, sleeve or sock form attached to the end of the sweep cable, and a second electrode positioned forwardly of the body to be towed and extending along and connected to the towing cable. A rectifier and transformer on the body convert AC power fed to the towed body from the towing vehicle, to DC power applied across the first and second electrodes. A plurality of fairings attached to the towing cable each have an electrically conductive portion electrically isolated from the towing cable. The electrically conductive portions are electrically connected together to form the second electrode. Each fairing has a plastic nose piece attached to the towing cable and an electrically conductive metal tail piece.
1. A plurality of fairings for use in an open loop magnetic field minesweeping system having a towed body and a sweep cable and electrode extending rearwardly from the towed body, said towed body to be towed through sea water by a towing cable extending forwardly of the towed body and connected between the towed body and a helicopter, other aircraft vehicle or marine vehicle, wherein each of the plurality of fairings is a separate discrete unit having a non-conductive portion for attaching to said towing cable and an electrically conductive portion electrically isolated by the non-conductive portion from the towing cable, said electrically conductive portions being electrically connected together to form an electrode forward of the towed body to be powered from the towed body.
2. The plurality of fairings of claim 1 , wherein said electrically conductive portions are electrically connected together by flexible electrical conductors.
