ABSTRACT:
The present invention relates in general to electromagnetic detonation of underwater sea mines.
BACKGROUND OF THE INVENTION
The clearing of sea mines at underwater locations for removal of shipping threats may presently be accomplished by remote controlled generation of a magnetic field causing detonation of the sea mine some distance from the source of electrical energy from which the magnetic field is derived. Usually a gas turbine powers an electrical generator as the foregoing referred to source of electrical energy, carried on a ship or towed water platform. Such mine clearing arrangements are relatively expensive and require a significant amount of maintenance. It is therefore an important object of the present invention to provide a mine clearing system that is less costly and much simpler to operate and maintain.
SUMMARY OF THE INVENTION
In accordance with the present invention a relatively small underwater vehicle carries a source of electromagnetic energy from which a magnetic field is produced and emitted from the vehicle simulating the magnetic signature of a larger surface ship. Such magnetic field is effective to detonate a sea mine at an underwater location in the vicinity of the vehicle to which it is being towed at a preselected sea water depth and speed by an air traveling helicopter connected to the underwater vehicle by a towing cable. Under such travel conditions of the underwater vehicle, powered rotation of impellers mounted thereon is induced to drive an electrical generator as the source of the electromagnetic energy.
