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:
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.
