Fastening metal part to composite part with through-hole
The granted patent (Publication Number: US11904387B2) discloses a novel piece comprising a first metal part and a second part made of organic matrix composite material. The first part includes a connecting portion, while the second part features a connecting portion with at least one through-hole. The second connecting portion is sandwiched between the first connecting portion and a metal fastening element, which is secured onto both the first connecting portion and another part, effectively fastening the two parts together. Additionally, the first connecting portion may have blind holes that align with the through-holes in the second connecting portion, allowing the fastening element to extend into the blind holes for further reinforcement.
Furthermore, the patent details the specific geometric configurations of the blind holes and through-holes, emphasizing their convergent shapes to enhance the fastening mechanism. The piece is designed with a shoulder on the first connecting portion to interact with the second connecting portion, ensuring a secure connection. The fastening element is produced using additive manufacturing through cold gas spray deposition of metal powder, with a protective layer between the fastening element and the second connecting portion. The piece, which exhibits general shape with rotational symmetry, is particularly suited for use as a combustion chamber jacket in a rocket engine. The patent also covers a rocket engine incorporating the described combustion chamber jacket, highlighting the practical application of the innovative design in aerospace technology.
