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.

Abstract: A method for carrying out deep holes and/or bottle-boring, in particular borings, with a high ratio between final linear depth and hole diameter, higher than 14:1, comprises the steps of: carrying out a reference hole, having axis and diameter linked to the deep hole to be carried out by a predetermined spatial relationship; making a deep hole of a diameter smaller than the hole to be carried out, so that said reference hole and said first deep hole be in spatial communication; and prearranging a guiding and supporting element internal to said reference hole and connecting thereto a tool shaft and a related tool to obtain a contour internal to the deep hole and/or a deep hole of diameter and axis according to said predetermined spatial relationship.

Abstract: A bogie-type landing gear for aircraft is provided. The landing gear includes at least one front wheel and at least one rear wheel connected to a beam, a rocking arm centrally and rotatably connected to said beam, and a shock absorbing element. The rocking arm ends and the shock absorbing element, which are distal to the wheels, are articulated on a lever element hinged on the aircraft frame, onto which an actuator assembly for rotating said lever element urges between a position in which the wheels are in an operative configuration and a position in which the wheels are retracted in the landing gear bay.
