Patent attributes
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, to produce component geometries and topologies that reduce the overall weight of the joint assembly while maintaining or improving its structural integrity. For example, the clevis lobes may include a plurality of gaps, such that the remaining material forms a shear web. The gimbal ring may also include strut or truss networks to enhance structural integrity.
