  • Systems, methods, and devices for additive manufactured ultra-fine lattice structures for propulsion catalysts
    Patent number: 12053767
    Abstract: In one aspect, a method for manufacturing a lattice structure for use as a propulsion catalyst includes: (a) providing a powder bed of one or more metal powder materials, (b) heating a portion of the powder bed to a temperature sufficient to melt the one or more metal powder materials, (c) forming a layer of the lattice structure, wherein the layer is formed by melting the one or more metal powder materials in a predefined pattern, (d) constructing the lattice structure, wherein the lattice structure is constructed by repeating steps (a)-(c) for each of a plurality of layers of the lattice structure until the lattice structure is constructed, and (e) removing excess materials from the constructed lattice structure.
    Type: Grant

  • Method for Fabricating Seal-Free Multi-Metallic Thrust Chamber Liner
    Publication number: 20190329355
    Abstract: A method for fabricating a thrust chamber liner for a rocket engine commences with a ring made from a first material on a build plate. A base layer of a second material in powder form is deposited on the exposed axial end of the ring. A laser beam is directed towards the base layer and the ring such that energy associated with the laser beam melts the base layer and a portion of the ring adjacent to the base layer. A melted portion of the base layer intermixes with a melted portion of the ring. Following this step, additional layers of the second material are deposited on the base layer. The first axial end of the ring is then exposed and additional layers of the first material are deposited on the first axial end of the ring.
