Abstract: A method is taught for the joining of a plurality of heat exchange tubes having a predetermined shape, such as a "Mae West" form, so as to obtain a tube bundle comprising a rocket engine thrust chamber. These tubes are joined to each other by laser powder injection welding, so as to close any gaps between adjacent tubes, and to securely bond the tubes together. A structural jacket is then affixed to the tube bundle, either in situ, by continuing to laser powder injection coat the surface, using an appropriate jacket composition, flame spraying or plasma spraying a suitable alloy in place, or by brazing or welding a previously formed jacket in place. In an extension of the invention, laser powder injection is performed to provide a repair method for the tube bundle, should the bundle be damaged or exhibit imperfect joining.

Abstract translation: 教导了具有预定形状的多个热交换管（例如“Mae West”）的接合方法，以获得包括火箭发动机推进室的管束。 这些管通过激光粉末喷射焊接彼此连接，以便封闭相邻管之间的任何间隙，并将管牢固地结合在一起。 然后，通过继续使用适当的护套组合物，火焰喷涂或等离子体喷涂合适的合金，或通过钎焊或焊接先前形成的表面，通过继续激光粉末注射涂覆表面，将结构护套固定到管束上 夹克到位 在本发明的延伸中，如果束损坏或呈现不完美的接合，则执行激光粉末注射以提供管束的修复方法。
