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).
Abstract:
A light indication system for airport runways, road routes and the like, comprising a circuit (9) consisting of at least one series of LED-type individual lighting units (4) arranged in series along an electric line (12, 13), being part of the circuit (9), comprises an AC/DC converter (11) for powering the electric line (12, 13) with direct current, the converter in turn comprising a constant current regulator (CCR) (11a), so as to maintain the power supply current constant even after faults; each lighting unit (4) is connected to a protection device (14, 15) designed to prevent the line (12, 13) from being interrupted should the relative lighting unit (4) develop a fault.
Abstract:
A guide apparatus for supports (20) for sensors (30) able to move by translation in fixed guides (10) integral with the sail (Ia) of submarines (1) and the like upon activation of an actuator (40), where the fixed guide (10) has a polygonal cross-section, at each vertex (10b) of the guide (10) there being at least one structure with the shape of a prism (11) extending in the vertical direction (Z - Z) along the entire body of the guide, the prismatic elements (11) extending towards the inside of the guide (10) in such a way as to form at least two sliding surfaces (12) for corresponding sliding blocks (22) belonging to the tube (20) to be moved by translation.
Abstract:
A propulsion unit for boats or the like comprises two propellers, respectively front (300) and rear (400), coaxial and contra-rotating, rotationally driven by the shaft (2a) of at least a main motor (2), the rear propeller (400) rotating at a speed of rotation different to the speed of rotation of the front propeller (300).
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.
