Abstract
A method of making a rocket thrust chamber is described in which molten metal is sprayed onto the outer shell of a cooling tube bundle, and the ends of tubes are covered with predetermined thicknesses of the metal. Circumferentially extending manifold channels that intersect each of the tube ends are then machined into the predetermined thicknesses of metal, and mating assemblies are attached to enclose the manifold channels.
