Verfahren zur Herstellung eines Raketenschubrohres

摘要

A method of making a rocket thrust chamber from an anomalistic tube bundle includes providing an anomalistic tube bundle 12 including a plurality of tubes 16 and a plurality of bonds between the tubes. At least one of the bonds is discontinuous, defining a gap 28 between one of the tubes and another of the tubes immediately adjacent thereto. The gap 28 is filled with a bridging material 34 comprising a binder and filler particles, the bridging material 34 in the gap 28 defining a patch 36. The tube bundle 12 and the patch 36 are heated to a conditioning temperature, which is maintained until particles have become sintered and the binder material has vaporized. Molten metal is then sprayed onto the patch 36 and the tube bundle outer shell 26 until a predetermined thickness of the metal covers the tube bundle outer shell. The predetermined thickness of metal is then machined to the predetermined dimensions of the structural jacket of the chamber.
