  • Method and device for helicopter-borne mine countermeasures
    Patent number: 6069842
    Abstract: The invention relates to underwater mines countermeasures methods and devices that can be employed from a helicopter.It consists in using the body (101) of a known passive heli-winched sonar, fitting to it emitting antennas (105, 106) arranged in this body parallel to its axis and a receiving antenna perpendicular to this axis and formed of two articulated arms (107, 108) that can be retracted inside the body. Two other arms (114, 113) that can be retracted into the body have propulsion means (111, 112) at their free ends, to allow the body to be stabilized about its axis.The invention makes it possible to employ lightweight helicopters for underwater mines countermeasures, allowing the mines to be relocated and, if appropriate, destroyed without having to backtrack.
