A guide assembly for an aircraft propulsion unit, the guide assembly having a first element and at least one guide element attached to the first element. The guide element includes a bottom wall, two lateral walls connected together by the bottom wall, and an opening defined between the bottom wall and the lateral walls. The opening is configured to receive at least partly a second element configured to move relative to the guide element. The guide element can further include at least one pair of gripping tongues cooperating with holding members of the first element to retain the guide element on the first element.

Systems for thrust reverser link arm connections are described herein. A fitting for a thrust reverser link arm may comprise a base plate configured to be fastened to a proximal surface of an inner fixed structure (IFS), a first wall extending orthogonally from the base plate, a pin extending orthogonally from the first wall, a second wall extending orthogonally from the base plate, a removable member, a first column located between the first wall and the second wall, and a second column located between the first wall and the second wall. The removable member may surround at least a portion of the pin. The removable member may be removed from a radially outward side of the IFS.

A system and method for an improved thrust reverser is provided. The provided thrust reverser employs hidden linkage assemblies to decrease drag in the engine exhaust flow and increase turbine engine performance. The hidden linkage assemblies are placed in a space between the blocker door and the transcowl, thereby not affecting the engine exhaust flow.

Aspects of the disclosure are directed to a thrust reverser system of an aircraft comprising: a translating cascade sleeve, a blocker door, and a kinematic mechanism configured to actuate the blocker door, the kinematic mechanism comprising: a first link coupled to the translating cascade sleeve, a second link coupled to the first link and a fixed structure, and a third link coupled to the first link and the blocker door.

A thrust reverser assembly for a turbine engine can include a core engine surrounded by a nacelle. A bypass duct can be formed in the space between the core engine and the nacelle. A blocker door can be movable to a deployed position extending into the bypass duct. A stop can be provided on the core engine to abut and support force applied to the deployed blocker door. The stop can have an airfoil shape.

An engine cowling of an aircraft gas turbine with a front area and a rear area that is displaceable in the axial direction, characterized in that the rear area is mounted and supported by means of multiple length-adjustable thrust reversal actuators that are arranged at an angle to one another.

An assembly is provided for an aircraft propulsion system. This assembly includes a thrust reverser cascade, a fan ramp fairing and a blocker door. The thrust reverser cascade extends along an axial centerline from a forward cascade end to an aft cascade end. The fan ramp fairing is disposed at the forward cascade end. The fan ramp fairing is configured with a fairing surface that provides a forward boundary for bypass air flowing into the thrust reverser cascade during a first mode of operation. The blocker door is configured to completely axially overlap the fairing surface during a second mode of operation.

A gas turbine engine includes a first annular portion that is stationary and adapted for partially surrounding an engine core. The first annular portion includes a fore pylon connecting portion. The gas turbine engine also includes a rail coupled to the fore pylon and extending in the aft direction from the first annular portion. The gas turbine engine also includes a second annular portion, arranged aft of the first portion and coupled to the rail. The second annular portion is movable along an engine core centerline between a closed position and at least one open position. The second annular portion is configured to engage the first annular portion in the closed position, thereby providing access to the engine core. The gas turbine engine further comprises a thrust reverser arranged in the second annular portion.

A measuring rake, configured to be arranged on a link rod, includes a sheath including a front face and two side walls delimiting between them a recess configured to receive the link rod, an electronic circuit arranged on the front face of the sheath and including at least one sensor, a patched leading edge fixed removably to the sheath, and a seal arranged between the patched leading edge and the electronic circuit, the patched leading edge including a plurality of air intakes, each forming a fluidic passage between an outer face and an inner face of the patched leading edge opening out facing at least one sensor of the electronic circuit, the measuring rake making it possible to obtain a measuring tool which can be assembled simply and quickly, with easy access to the electronic circuit, and making it possible to avoid problems of orifice blockages or air leaks.

To reduce the size of an aircraft engine, an assembly is disclosed including a nacelle section, a gas exhaust cone positioned radially towards the inside in relation to the nacelle section and forming therewith an annular gas exhaust channel, and a reverse thrust system including moveable gas diversion elements for the gas flowing in the annular channel, at least one actuator and a transmission device linking the at least one actuator to the moveable gas diversion elements. Furthermore, the actuator is located inside the gas exhaust cone.
