Abstract: A deck landing system for aircrafts, in particular rotating wing aircrafts, apt to implement a hook between the aircraft and the deck of a ship or of a floating platform, the deck being equipped with a target grid plate, it does not require the use of hydraulic systems and it comprises: a telescopic actuator (1) with a harpoon (3) having, at its own distal end, hooking grippers (7); and a control unit (9) which actuates said telescopic actuator (1), wherein the telescopic actuator (1) comprises a linear electromechanical actuator (8) having: a main battery (13) fed through a unit (12) for converting and conditioning the energy and connected to said telescopic actuator (1); and a device (10) for recovering and releasing the kinetic energy generated by the waves with the aircraft locked on said deck, is of the type acting with super-capacitors, which feeds said main battery (13).

Abstract: A landing gear assembly, having an electromechanical device for actuating the landing gear and locking and releasing device, includes: a rotary actuator acting on the assembly at the hinge point, having a rotary electric motor connected to an actuating arm, to rotate the assembly around a respective actuation axis with an interconnection so that, in case of power supply failure, the actuator is free to rotate dragged by the assembly by free fall; and a linear actuator, integral to the assembly and movable therewith, and which includes a rotary electric motor and a cam mechanism to transform rotary motion of the motor into an axial motion of a locking pin. The actuation axes of the rotary actuator and of the linear actuator are parallel, and the rotation axis of the rotary electric motor of the linear actuator coincides with the linear actuation axis of the locking pin.
