A translating cowl thrust reverser system with efflux management includes a support structure, a transcowl, a cowl shield, and a single cascade structure. The transcowl and cowl shield are moveable together between a first position, in which the transcowl abuts the support structure, and a second position, in which an aperture is formed between the transcowl and the support structure. The cowl shield has cowl shield turning vanes. The single cascade structure is disposed within the aperture and includes a forward wall, a curved vane, internal turning vanes, and external turning vanes. In the first position, each cowl shield turning vane is disposed between a different pair of external turning vanes. The cowl shield turning vanes, the internal turning vanes, and the external turning vanes turn the airflow so that it is directed substantially perpendicular to, and vertically outboard relative to, a plane of symmetry.

A position sensor for an aircraft nacelle thrust reverser door for an aircraft turbojet engine includes a target to be detected, a detector having a detection range and including a detection head configured to detect the target when it enters its detection range, and a target guide configured to guide the target in order to position it in the detection range of the detector. The detector is stationary relative to the target guide. In one form, the target is intended to be positioned on the door, and the detector and the target guide are intended to be positioned on a stationary structure of the thrust reverser. In another form, the target is intended to be positioned on a stationary structure of the thrust reverser, and the detector and the target guide are intended to be positioned on the door.

A thrust reverser for an aircraft propulsion assembly, this reverser including a lower door and an upper door defining, in thrust reversal configuration, a deflection opening, through which a portion of the fluid not serving to produce the thrust reversal of the aircraft can exit the reverser downstream. The downstream edge of the lower door is offset towards the rear with respect to the downstream edge of the upper door so as to orient the fluid flow passing through the deflection opening vertically upwards. When the propulsion assembly is mounted at the rear portion of the fuselage of the aircraft, this makes it possible in particular to improve the supply of the control surface of the aircraft in the landing phase, in particular in crosswind conditions.

The subject matter of this specification can be embodied in, among other things, a system that includes a flexible structure, a power inverter, a first electromechanical device configured to urge movement of a first portion of the flexible structure based on power received from the power inverter, a second electromechanical device configured to urge movement of a second portion of the flexible structure based on power received from the power inverter, a feedback sensor configured to provide a feedback signal indicative of alignment between the first portion and the second portion, and a controller configured to control operation of at least one of the first electromechanical device and the second electromechanical device based on the feedback signal.

Disclosed herein is a blocker door for use in a thrust reverser portion of a nacelle. The blocker door includes a structural frame having a plurality of connected and crossing ribs. The blocker door also includes a front sheet positioned on an airflow side of and attached to the structural frame. The blocker door also includes at least one acoustic core positioned between the ribs of the structural frame and comprising a plastic material.

A variable area nozzle assembly for a gas turbine engine includes a fixed structure including a first fixed ring and a second fixed ring. The second fixed ring is spaced axially aft from the first fixed ring to define a first portion of an ejector passage therebetween. A nozzle defines an inner radial exhaust flow path surface. The nozzle includes a forward ejector door and an aft ejector door. The forward ejector door and the aft ejector door define a first surface portion of the inner radial exhaust flow path surface. Each of the forward ejector door and the aft ejector door are pivotable between respective closed positions and respective open positions. A translating ejector sleeve is mounted within the fixed structure and configured to axially translate within the fixed structure between a first axial position and a second axial position.
