Abstract : The patent relates to a composite wall, and a method of manufacturing it, for a regeneratively cooled thrust chamber of a liquid propellant rocket engine. The composite wall of the thrust chamber comprises: an outer wall component of high strength lightweight alloy; a middle wall component of nickel abutting with and joined to the outer wall component, with the middle wall having a plurality of lands thereon and a plurality of grooves therein; and, an inner wall component of material of high thermal conductivity and high temperature strength and ductility, with the inner wall component abutting with and joined to the lands on the middle wall component, thereby forming liquid propellant coolant passages of the channel type.
