Produktionsweise für einen regenerativen Wärmetauschkreislauf für hohen Wärmefluss, insbesondere für Raketenbrennkammern

摘要

The method includes a number of steps. The first step involves production of an intermediate layer (12) on a support mandrel (11) representing the interior profile of the structure (10). The second step involves production of a series of channels uniformly distributed around the mandrel for soluble inserts. The third step involves preheating of the mandrel and production of the body (14) of the structure (10) by a thermal deposition process under vacuum. The fourth step involves machining of the channels in the body and introduction of soluble inserts. The fifth step involves production of a closing layer (17) and an outer envelope by a thermal deposition process under vacuum, after preheating. The sixth step involves removal of the soluble inserts and the intermediate layer (12).
