Abstract:
Described is a visual indicator device for landing aircraft (2) on the deck (3) of a ship (4), comprising a unit for measuring the instantaneous rolling motion angle of the ship (4), a light projection apparatus (6) designed to project, on a non-horizontal wall (5) of the ship (4), at least a first rectilinear segment (7) representing the horizon line.
Abstract:
Here below is described a naval azimuth propulsion system (1) comprising an electric motor (2), a propeller (4) operatively connected to the electric motor (2) to rotate about a relative central axis (M), an annular nozzle (12) positioned coaxially around the propeller (4), elements (6) for supporting the motor (2) and the propeller (4), these elements (6) being connectable to the hull of a ship, first magnetic shielding means designed to shield the magnetic field generated by the electric motor(2) during its operation.
Abstract:
Described is an apparatus for sweeping influence mines, comprising an operating unit (2) having a plurality of propulsion devices (8) designed to be immersed in water and at least one floating body connected to the propulsion devices (8), the latter being designed to overcome the hydrostatic thrust acting on the floating body to keep the operating unit (2) immersed at a predetermined depth.
Abstract:
The stabilising device for boats comprises two propulsion units (2) emerging from a hull of the boat and positioned on opposite sides of a boat longitudinal axis (A3), each of the propulsion units (2) comprising a fin (3) and motor means for rotating the fin (3) both about its first axis (Al) of longitudinal extension, and about a second axis (A2).
Abstract:
The nautical propulsion system apparatus for surface and/or underwater navigation comprises a propulsion system body (101), a unit (1) for feeding a delivery or primary flow to the propulsion system body (101); the feed unit (1) comprising an internal combustion engine (2) and a pump (3) driven by the internal combustion engine (2).
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).
Abstract:
A movement system for submarine-atmospheric interface devices comprises fixed guides (4) integrally connected to a conning tower (103) of a submarine (100), a lifting apparatus (1) slidable in the fixed guides (4), at least one electric motor (5) for driving the lifting apparatus (1) and a motion transmission mechanism (6) whereby motion is transmitted from the electric motor (5) to the lifting apparatus (1) and comprising flexible transmission means (7).
Abstract:
An apparatus for launching a remotely piloted aircraft (50) from a submarine (100) comprises a tubular body (2) insertable into a mast (103) of the submarine (100), extending along a respective principal direction (C) and defining an ejector mouth (3) for the remotely piloted aircraft (50), a projectile (10) housed in the tubular body (2) and comprising the remotely piloted aircraft (50) and launching means (4) by which the projectile (10) is propelled into the air from the mast (103) of the submarine (100). The launching means (4) comprise a pneumatic ejection device (5) connected to the tubular body (2) and configured to push the projectile (10) out of the ejector mouth (3) until reaching a first height (Ql) and a fuel-driven propulsion unit (11) connected to the projectile (10), during launching, and designed to be activated when the projectile (10) is outside the tubular body (2) to propel it to a second height (Q2) greater than the first height (Ql).
