A flexible joint assembly for a joint between a first duct and a second duct for providing a flow of fluid, such as bleed air in an aviation implementation. The flexible joint includes a bellows supported by a mounting assembly having a first support and a second support, each surrounding a portion of the bellows. A gimbal ring assembly of the joint assemblies can operably couple the first support and the second support.

A flexible joint assembly for a joint between a first duct and a second duct for providing a flow of fluid, such as bleed air in an aviation implementation. The flexible joint includes a bellows supported by a mounting assembly having a first support and a second support, each surrounding a portion of the bellows. A set of flexures provided on a joint ring of the joint assemblies can operably couple the first support and the second support.

A flexible joint includes a pair of generally tubular members and a ring (e.g., gimbal ring). The tubular members are pivotally connected to the ring by pivot pins such that the pivot axes of the tubular members is generally perpendicularly related to each other to form a hinge. A support structure may interconnect the pivot pins and may be configured to support the pivot pins across the joint to maintain a generally perpendicular hinge orientation. A conduit may connect the tubular members.

The invention relates to a multipart pipe joint (10) having a centre piece (16) on which joint parts (18, 20) are received which are pivotable relative thereto and which are rotationally fixed to the centre piece (16) at articulation points (22, 24). The articulation points (22, 24) of the joint parts (18, 20) on the centre piece (16) also represent articulation points (22, 24) for transmission elements (42) which extend axially along an inner wall (34) of the centre piece (16). The articulation points (22, 24) forming articulation axes are arranged in an axial offset (25) to each other. Furthermore, the invention relates to the use of the multipart pipe joint (10) in an aircraft.

A flexible connection for use between a vertical, large diameter cold water conveying pipe and a floating platform that supports the cold water conveying pipe or another pipe to permit the pipe and the platform to rotate in roll and pitch directions relative to one another without imposing excessive bending moments or strain on the cold water pipe. The flexible connection also contains internal and external pressure across the connection. The flexible connection includes an articulation mechanism that interconnects the vertical cold water conveying pipe and the platform or a pipe on the platform, and a flexible, fluid impermeable bellows.

A sealed joint assembly for transmitting high temperature and high pressure fluid between adjoining ducts in, for example, an aircraft bleed air system, includes a gimbal ring and two annular clevises. Each clevis includes a pair of axially-extending lobes that each includes a bore hole extending therethrough. The bore holes of the clevis lobes may each align with a respective bore hole formed within the gimbal ring, through which a pin may be inserted to couple the clevises to the gimbal ring. The clevises and gimbal ring may be formed using additive manufacturing. The gimbal ring may include a strut or truss network, and may be comprised of an inner gimbal ring and an outer gimbal ring.

A joint assembly for joining a first component to a second component includes a first clevis including first clevis apertures and a second clevis including second clevis apertures. The joint assembly includes a first bearing insert and a second bearing insert fixedly coupled to the first clevis and the second clevis, respectively. The joint assembly includes a ring surrounding the first clevis and the second clevis and including a plurality of ring apertures. The joint assembly further includes a plurality of pins received within the corresponding ring aperture. Each pin includes a head portion and a shaft portion extending from the head portion. The shaft portion is coupled to the ring by a corresponding interference fit. The shaft portion is coupled to the corresponding first or second bearing inserts by a corresponding clearance fit such that the shaft portion is rotatable relative to the corresponding first or second bearing inserts.

A pipe includes at least one first section connected to a second section by a hinged element allowing a predetermined angular movement of the first section relative to the second section under a predetermined minimum force. The hinged element includes two end pieces connected respectively to the first section and to the second section and hinged with each other to allow the angular movement, and a tube having ends connected to the end pieces so as to be elastically deformable under the predetermined force according to the predetermined angular movement. The sections and the end pieces themselves are rigid under the predetermined minimum force. A treatment facility include such pipes.

An aircraft assembly is disclosed including a rib of a wing, an aperture in the rib, and a pipe assembly extending through the aperture. The pipe assembly includes a first rigid pipe section, a second rigid pipe section and a flexible pipe section between the first and second rigid pipe sections; and a fixture arrangement that couples one of the pipe sections to the wing rib. The flexible pipe section is located at a plane of the rib and configured to allow relative movement between the first rigid pipe section and the second rigid pipe section.

An irrigation system joint couples first and second adjacent pipe sections that are coaxial along a central axis when aligned. The joint comprises a first portion and a second portion. The first portion is for securing to the first pipe section and comprises an upwardly facing hemispherical surface. The second portion is for securing to the second pipe section and comprises a cavity that receives at least a portion of the hemispherical surface to form a contact line coincident with the central axis when the pipe sections are aligned.
