HINGE JOINTS FOR AIR INTAKE SYSTEMS Russian patent published in 2022 - IPC F16L27/08 F16L51/02 

FIELD: pipelines connection.

SUBSTANCE: inventions group relates to airtight swivel joints for flexible connection of pipelines, which move fluids with high temperature and high pressure, for example, for piping systems for air sampling in aircraft or space vehicles. Sealed docking station for transporting high temperature and high pressure fluid between adjacent pipelines contains a swivel ring and two ring clamps. Each yoke contains a pair of petals extending in the axial direction, each of which contains a bored hole passing through them. Each collar tab bore can be aligned with a corresponding bore formed within the swivel ring through which a pin can be inserted to connect the yokes to the swivel ring. Stirrups and the swivel ring can be formed using additive manufacturing to create component geometries and topologies that reduce the overall weight of the docking station while maintaining or improving its structural integrity. For example, the tabs of the collars may contain a plurality of gaps so that the remaining material forms a shear mesh.

EFFECT: swivel ring may also contain grids of struts or skewers to improve structural integrity.
