HYBRID PIVOT DOOR THRUST REVERSERS
A thrust reverser is disclosed. The thrust reverser includes a frame, a first reverser door pivotally mounted to the frame, a second reverser door pivotally mounted to the frame and a hybrid exhaust duct. A first trailing edge of the first reverser door forms a portion of an exit plane of the thrust reverser and a second trailing edge of the second reverser door merges into the hybrid exhaust duct.
Controlling a relative position at an interface between translating structures of an aircraft nacelle
A nacelle is provided for an aircraft propulsion system. This nacelle includes a stationary support, a fanlet, a thrust reverser sleeve and an interface assembly providing an interface between the stationary support, the fanlet and the thrust reverser sleeve where the fanlet and the thrust reverser sleeve are respectively in stowed positions. The stationary support extends circumferentially about an axial centerline. The fanlet includes an inlet structure and a fan cowl. The fanlet is configured to translate axially along the centerline. The thrust reverser sleeve is configured to translate axially along the centerline. The interface assembly includes a pair of interlocking components, wherein a first of the interlocking components is mounted to the fanlet at the aft end of the fanlet.
SYSTEMS AND METHODS FOR THRUST REVERSER WITH TEMPERATURE AND FLUID MANAGEMENT
A thrust reverser system for a gas turbine engine includes at least one hinge coupled to the thrust reverser system so as to be adjacent to at least one opening defined in the thrust reverser system. The thrust reverser system includes at least one body coupled to the at least one hinge. The at least one body has a first body end and an opposing second body end. The body pivotally coupled to the hinge such that a portion of the body is positionable within the at least one opening and the body includes at least one counterweight at the first body end or the second body end. The body is positioned within the at least one opening based on an operating condition of the gas turbine engine.
Translating cowl thrust reverser system with over-stow unlocking capability
A thrust reverser system for a turbine engine includes a support structure, a transcowl, a door, a lock, and a first elastic element. The transcowl is mounted on the support structure and is translatable between a stowed position, a deployed position, and an over-stow position. The door is pivotally coupled to the support structure and is rotatable between at least a first position, a second position, and a third position. The lock is movable between a locked position, to prevent transcowl translation toward the deployed position, and an unlocked position, to allow transcowl translation toward the deployed position. The lock is only able to move to the unlocked position when the transcowl is in the over-stow position. The first elastic element is disposed within the stowed position aperture and, when engaging both the support structure and the transcowl, supplies a force to the transcowl.
Cascade pivot door-type thrust reverser for turbofan engine
A thrust reverser for reversing a thrust of a turbofan engine of an aircraft. The reverser includes a pivot door, a cascade component, and an actuation system. The door is moveable between lowered and raised positions in which a side outlet is, respectively, covered and uncovered. The cascade includes turning vanes, and is moveable between forward and rearward positions in which the cascade is positioned, respectively, not over and over the side outlet. The actuation system deploys the reverser by simultaneously moving the door to the raised position and moving the cascade to the rearward position over the side outlet, and stows the reverser by simultaneously moving the cascade to the forward position and moving the door to the lowered position. When the door is raised and the cascade is over the side outlet, airflow through the side outlet is directed at least partially forward to provide reverse thrust.
