    • Described is a rotary mechanical transmission (T), comprising: a containment structure (1), a first rotary element (5), connected or connectable to a drive unit to define a mechanical power input unit and rotatable about an axis (X). The transmission (T) also comprises a fixed guide (9) and a second rotary element (10), rotatable about said axis (X) and defining a power output unit. The transmission (T) also comprises a connecting element (2) extending along the axis of rotation (X) and coupled to the first rotary element (5) by a first threaded connection (3, 8), in particular a lead nut and screw or recirculating ball or roller connection. The connecting element (2) is also coupled with one of either the fixed guide (9) and the second rotary element (10) by means of a second threaded connection (4, 14), in particular a lead nut and screw or recirculating ball or roller connection, and with the other of either the fixed guide (9) and the second rotary element (10) by means of a linear guide (15) parallel to the axis (X). The first threaded connection (3, 8) and second threaded connection (4, 14) have different pitches in such a way as to vary the angular speed between the connecting element (2) and the first rotary element (5).

    • An electric thrust reverser system for an aircraft engine nacelle and an aircraft engine nacelle provided with same. The invention concerns an electric thrust reverser system for an aircraft engine nacelle, comprising at least one mechanism (2 or 3) for actuating a thrust reverser mechanism like a reverser door. The actuating mechanism (2 or 3) comprises first (6) and second (7) drive cylinders. Each cylinder comprises a mechanical connection casing (9), a primary lock (8) and a mobile rod (10) rigidly connected to a point linked to the associated reverser mechanism, like a reverser door. A motorised drive unit (11) is connected mechanically by flexible shafts (12) to the mechanical connection casings (9) of each cylinder (6, 7) of the actuating mechanism (2 or 3) and set in motion under the control of a control unit (1) by means of an electrical connection (16, 17). A tertiary lock (13) is disposed to secure the associated thrust reverser mechanism like a thrust reverser door to a fixed structure of the nacelle.

    • An electromechanical actuating assembly (100) can have a redundant design with a first electric motor (300A) providing actuator-moving power via a first drive train (400A) and a second electric motor (300B) providing actuator-moving power via a second drive train (400B). A first decoupling train (600A) can transmit decoupling power to decouple the first drive train (400A) from the actuator (200) and a second decoupling train (600B) for transmit decoupling power to decouple the second drive train (400B) from the actuator (200). The assembly (100) is operable in a fault-tolerant mode wherein actuator-moving power is transferred only through one drive train (400A/400B) and the other drive train (400B/400A) is decoupled from the actuator (200).

    • The invention relates to a hinge for movable control surfaces in an aircraft. The hinge comprises two hinge lugs placed at a distance from one another. The hinge lugs include connecting lugs with an elongated connecting piece therebetween. An actuator is connected to the connecting piece conveying the force by means of fastening lugs to the hinge and further onto the control surface. The connecting piece is pivoted to the connecting lugs so that it can revolve about its longitudinal axis when moving the control surface. The invention also relates to a connecting piece intended to be used with a hinge like the one described above. The connecting piece is an elongated element including journals at both ends from where the connecting piece is rotatably pivoted about its longitudinal axis between the connecting lugs on the hinge. A middle portion of the connecting piece between the journals is flat and tapers towards the journals.
