Abstract:
A naval azimuth propulsion system including an electric motor, a propeller operatively connected to the electric motor to rotate about a relative central axis, an annular nozzle positioned coaxially around the propeller, elements for supporting the motor and the propeller, these elements being connectable to the hull of a ship, first magnetic shielding means designed to shield the magnetic field generated by the electric motor during its operation.
Abstract:
An apparatus for sweeping influence mines, including an operating unit having a plurality of propulsion devices designed to be immersed in water and at least one floating body connected to the propulsion devices, the latter being designed to overcome the hydrostatic thrust acting on the floating body to keep the operating unit immersed at a predetermined depth.
Abstract:
An air intake device for a submarine comprises a first fixed member connected to the submarine hull and a second member which is telescopically movable relative to the first member to rise up with an upper end of it above the water's surface to allow air to be taken in from the atmosphere during navigation of the submarine at periscope depth, the movable member mounting at its upper end a radar device designed to emerge from the water together with the selfsame movable member.

Abstract:
Described is a system for neutralising underwater explosive devices comprising an apparatus for identifying a naval mine (4), a source (8) for emitting an acoustic signal for signalling the position of the naval mine (4), a first underwater vehicle (5) designed to place the source (8) for emitting an acoustic signal (9) close to the naval mine (4), a measurement apparatus designed to determine a first distance (Rs) between the source (8) of emission of an acoustic signal and the naval mine (4).
Abstract:
An optical device (1) for indicating the glide angle of aircraft comprises at least one light source (2) of predetermined colour, at least one unit (4) for creating a light image, coinciding with the light source (2), and at least one unit (5) for projecting the light image at a distance. The light source (2) comprises an electroluminescent light panel (3).
Abstract:
Described is a lighting system for aircraft landing surfaces (2), comprising a plurality of electric lighting elements (3) arranged in an orderly sequence to help to form on the surface (2) a predetermined symbol (R1, R2), visible from the aircraft during landing, at least one branch box (7) for accessing the electricity network, the sequence of the lighting elements (3) forming a chain (6).
