Turbofan comprising a series of rotary blades for closing off the duct for the secondary stream
A turbofan with a sliding element, rotary blades that can rotate between stowed and deployed positions, and a maneuvering system which moves each blade when the sliding element moves and which includes, for each blade, a rotary main shaft, for each main shaft, a transmission lever rigidly secured to the main shaft, at least two connecting strips articulated to one another, wherein each connecting strip is associated with at least three main shafts, the transmission levers of which are articulated to the connecting strip, and a drive system which rotates the first connecting strip when the sliding element moves. The use of rotary blades on the sliding element and the simplified maneuvering system makes the assembly more lightweight compared to the use of conventional reverser doors.

Split sleeve hidden door thrust reverser
A system for a thrust reverser of an aircraft includes a primary sleeve and a secondary sleeve having cascades. The secondary sleeve is coupled to a set of blocker doors. The sliding motions of the primary sleeve and the secondary sleeve are not directly coupled when each moves between its stowed and deployed positions. The sliding motion of the primary sleeve may begin at a different time and continue at a different rate from the sliding motion of the secondary sleeve.

THRUST REVERSER COMPRISING AT LEAST ONE INITIATOR TO INITIATE THE CLOSING OF A MOBILE EXTERNAL STRUCTURE OF THIS REVERSER
A thrust reverser for an aircraft propulsion unit, this reverser including a fixed structure and a mobile external structure able to move between a closed position and an open position so as to cause the reverser to transition respectively between a direct-jet configuration and a reverse-jet configuration. The reverser includes, on the one hand, one or more actuators configured to move the mobile external structure between the closed position and the open position. The reverser includes, on the other hand, at least one initiator configured to apply to the mobile external structure a force that initiates a closure travel in which the mobile external structure is moved from the open position towards the closed position.

Nacelle for an aircraft turbojet engine provided with a device for detecting deformation of its movable structure
A nacelle for an aircraft turbojet engine includes a thrust-reversing device with a fixed structure and a movable structure translatably movable along an axis substantially parallel with a longitudinal axis of the nacelle between a retracted position in which it provides aerodynamic continuity with the fixed structure of the nacelle during operation of the nacelle with forward thrust and a deployed position in which it opens a passage intended for the circulation of a diverted secondary air flow during operation of the nacelle with reverse thrust. The nacelle includes at least one position sensor configured and arranged in the nacelle for detecting a deformation of the movable structure exceeding a permitted predetermined deformation threshold.
