Abstract: A rotor for a hover-capable aircraft is described, comprising: a hub rotatable about an axis and, in turn, comprising a plurality of blades; a mast connectable to a drive member of the aircraft and operatively connected to the hub to drive the hub in rotation about the axis; and damping means for damping vibrations transmitted to the mast, which comprise a mass designed to oscillate in a plane transversal to the axis so as to contain flexural vibrations of the mast generated by rotation of the blades; the damping means also comprise elastic means having a desired stiffness along the axis and operatively connected to the mass to contain vibration of the mast along the axis.

Abstract: A breech block assembly for a firearm includes a guiding element having a slide adapted to slide along a guide in an actuation system of the breechblock assembly driven by a motor. A shutting element shuts an opening in a breech ring of the firearm. A percussion pin is pushed by an elastic element slide along a longitudinal axis, as a function of the firing cycle of the firearm to an axial hole in the shutting element. The percussion pin is shaped to partially come out of the axial hole of the shutting element for firing a piece of ammunition. The breechblock assembly comprises a control system for controlling the percussion pin. The control system controls the operability and the movement of the percussion pin independently of a firing cycle of the firearm.

Abstract: An electrochemical-type power supply source for use in marine environment, is provided with: an electrochemical stack, which generates electric power in the presence, internally, of an electrolytic fluid; a first tank, designed to contain electrolytic fluid at a first temperature; a second tank, designed to contain electrolytic fluid at a second temperature, lower than the first temperature; a thermostatic valve, that mixes electrolytic fluid at a lower temperature with electrolytic fluid at a higher temperature, for generating a mixed electrolytic fluid to be introduced into the electrochemical stack at a controlled temperature for generating a desired electric power. The electrochemical power supply is further provided with an auxiliary tank, adapted to contain electrolytic fluid at a third temperature, higher than the first temperature; and the thermostatic valve is connected to the auxiliary tank and receives, at an input, the electrolytic fluid at the third temperature.

Abstract: A vertical take-off and/or landing aircraft comprising: a fuselage having a longitudinal axis; a pair of semi-wings protruding from the fuselage in a transversal direction with respect to the longitudinal axis; a pair of a predetermined breaking areas of the semi-wings defining respective preferred rupture sections at which the respective semi-wings are designed to break, during operation, in a controlled way moving along a preferred collapse trajectory in the event of impact; and at least one fluidic line configured to convey at least one service fluid from and/or towards at least one said semi-wing and crossing at least one of said preferred rupture sections; the aircraft comprises a self-sealing coupling movable between a first configuration in which it enables the flow of said service fluid from and/or towards the semi-wing, and a second configuration in which it prevents the above-mentioned flow and the spilling of the service fluid from the fluidic line; the self-sealing coupling is movable from the first to the second configuration via the movement of the semi-wing along the preferred collapse trajectory.
