A recently granted patent (Publication Number: US11925971B2) discloses a manufacturing method that involves forming a grid structure by creating apertures in a plate and bonding a sheet to it. The method includes the use of fittings, such as bases and flanges, which are bonded to either the plate or the sheet during the assembly process. The bonding process involves brazing the sheet to the plate, and machining is used to create the apertures in the plate. Additionally, stiffening ribs are integrated into the grid structure to enhance its structural integrity.

Furthermore, the patent describes the formation of multiple grid structures by repeating the process with a second plate and sheet. The second grid structure is bonded concurrently with the first one, and fittings are also attached during this bonding process. The method allows for the creation of grid structures with polygonal cross-sectional geometries and orthogrid structures. The materials used in the manufacturing process, such as nickel-based alloys, contribute to the durability and performance of the grid structures. The angular offset between the first and second grid structures adds versatility to their applications.
