MOUNTING APPARATUS FOR A GAS TURBINE ENGINE
A mounting apparatus for mounting a gas turbine engine to an aircraft. The mounting apparatus includes a thrust strut operably connected to the gas turbine engine and the aircraft. The thrust strut defines a thrust strut axis. The mounting apparatus further includes a restraining structure. The restraining structure includes a bracket circumferentially disposed on the thrust strut and at least one elongate member connected to the bracket and the gas turbine engine. The restraining structure radially and circumferentially constrains the thrust strut with respect to the thrust strut axis of the thrust strut while allowing the thrust strut to move in the direction of thrust strut axis.
AIRCRAFT ENGINE ATTACHMENT COMPRISING AT LEAST ONE SYSTEM FOR IMMOBILIZING A SHEAR PIN IN TRANSLATION COMPRISING A STOP PLATE, METHOD FOR MOUNTING SAID ENGINE ATTACHMENT AND AIRCRAFT COMPRISING SAID ENGINE ATTACHMENT
An aircraft engine attachment connecting an attachment body and a primary structure of an aircraft pylon, the engine attachment comprising a shear pin immobilized in translation by a first immobilization system that comprises a shoulder and a removable stop that are integral with the primary structure, between which a flange of the shear pin is immobilized, and a second immobilization system that comprises a stop plate, connected by at least one removable link to the primary structure, which closes the first hole, at least in part.
AIRCRAFT ENGINE ATTACHMENT COMPRISING AT LEAST ONE FORK-TYPE SYSTEM FOR IMMOBILIZING A SHEAR PIN IN TRANSLATION, METHOD FOR MOUNTING SAID ENGINE ATTACHMENT AND AIRCRAFT COMPRISING SAID ENGINE ATTACHMENT
An aircraft engine attachment connecting an attachment body and a primary structure of an aircraft pylon, the engine attachment comprising a shear pin immobilized in translation by a first immobilization system that comprises a shoulder and a removable stop that are integral with the primary structure, between which a flange of the shear pin is immobilized, and a second immobilization system that comprises, first, a groove positioned in an extension of the shear pin and, second, a fork connected to the primary structure via at least one removable link and interacting during operation with the groove in such a manner as to immobilize the shear pin in translation.
AIRCRAFT PROPULSION ASSEMBLY
A propulsion assembly for an aircraft, comprising a pylon to be secured below a wing of the aircraft and having a front face and a lower face, and a turbomachine comprising, from upstream to downstream in a direction of a flow of air passing through the turbomachine during operation, a fan and an engine driving the fan. The fan is faired by a fan casing and the engine is faired, from upstream to downstream, by an intermediate casing and an engine casing, the intermediate casing having a hub and an outer ring extending the fan casing, the ring being spaced apart radially from the hub and secured to the latter by arms extending in an air duct. The propulsion assembly comprises a front engine attachment secured between the pylon front face and the hub and a rear engine attachment secured between the pylon lower face and the engine casing.
PROPULSION ASSEMBLY FOR AN AIRCRAFT, COMPRISING A LOAD SUPPORT
A propulsion assembly having a pylon, a turbomachine comprising an engine and a fan that is enclosed by a fan casing, a nacelle surrounding the engine and the fan casing and having a load support disposed in the top part of the nacelle, a front engine attachment between the pylon and a front part of the engine, a rear engine attachment between the pylon and a rear part of the engine, a front fan attachment between the fan casing and the load support, and a rear pylon attachment between the pylon and the load support. Such a propulsion assembly allows a reduction in bulk since the load of the turbojet engine is distributed between the load support and the pylon, and the pylon is attached to the engine.
ATTACHMENT FOR SUSPENDING AN AIRCRAFT ENGINE
An attachment for attaching an aircraft engine with a first receiving element to an aircraft structure with a second receiving element may include at least three fasteners and a stacked layer. Stacked layer may include at least two sheets, at least three holes through the stacked layer, a first connecting portion that includes a first hole of the at least three holes, a second connecting portion that includes second and third holes of the at least three holes, and a suspension portion that is located between the first connecting portion and the second connecting portion.
Assembly for an aircraft comprising an engine of the “open rotor puller” type and means for attaching the latter to the rigid structure of an attachment pylon
To allow the attachment of an engine of the Open Rotor Puller type to the rigid structure of an attachment pylon, an attachment structure comprises a first attachment structure shifted forwards with respect to the center of gravity of the engine and connected to the rigid structure through a pyramid, a second attachment structure laid out at the rear with respect to the first attachment structure and extending in a plane of a first stringer of the rigid structure, and a third attachment structure laid out at the rear with respect to the second attachment structure. The second attachment structure comprises two engine attachments for recovering the moment along the axis of the engine, laid out on either side of a horizontal symmetry plane of the engine.
Ball joint device for a turbine engine
The ball joint device (10) for suspending a turbine engine from a strut or suspending equipment on the body of a turbine engine. Said device comprises a first member (12), one end of which carries a ball joint (14) and is interposed between the two lugs (16, 17) of a second member (18), the ball joint comprising a bore (28) for the passage of a shaft (30), the ends of which shaft pass through openings (20, 22) in the lugs. A first (16) of the lugs comprises or carries first means for axially holding the shaft on the side opposite the ball joint, which means comprise a cover (52, 52), and a second (17) of the lugs comprises or carries second means (38) for axially holding the shaft on the side opposite the ball joint. The device further comprises a resilient member (62, 62) that is deformable under compression and is held by the cover, said resilient member (62, 62) being designed to bias a support element (40), through which the shaft passes and which is in axial abutment on the ball joint (14), axially in a direction away from the cover.
Turbine engine including a thermal protection member
A turbine engine includes an element (3), comprising a wall (11) and at least one load-bearing member (17) extending substantially perpendicularly relative to the wall (11), with said member (17) being intended to be attached onto a mounting (18) used for the attachment thereof onto an aircraft structural part. A thermal protection member (23) surrounds said member (17), with said thermal protection member (23) including a base flexibly supported on the wall (11) of the element (3), with said base matching the shape of said wall and at least one covering part which surrounds said load-bearing member.
Under the wing-mounted jet engine with pivotal swivel joint to produce directional thrust vectoring thru swivel angle
During flight of a jet aircraft the essential steering movements, such as roll, pitch and yaw maneuvers, are normally performed via control surfaces on its wings and its tail sections. This invention allows for swiveling of jet engines mounted under wings of the jet aircraft, to direct exhaust gases upward, downward or sideways to some limited extent to achieve more agile air maneuvers compared to traditional fixed under the wing-mounted jet engines. The idea of performing more agile air maneuvers is realized by swiveling and pivoting the jet engine under the wings of the jet aircraft about a pivot point mounted along an engine nacelle to enable highly efficient pitch and roll motions in flight, as well as making efficient and agile yaw type motion in flight by swiveling and pivoting the jet engines underneath the wings.
