TLDR
In this article, a low-melting alloy is used as a filler to fill the grooves in the outer side of a rocket combustor. But the inner cylinder is formed by forming a Cu plating shell on the periphery of the inner cylin.Abstract:
A method of producing rocket combustors wherein in forming an outer cylin by a powder metallurgical method on the outer side of a cylinder provided on its outer periphery with a cooling wall of channel construction having a plurality of grooves, a low-melting alloy is used as a filler to be filled into the grooves. It is also possible to form the outer cylinder after forming a Cu plating shell on the periphery of the inner cylinder filled with the low-melting alloy.read more

Methane conversion apparatus and process using a supersonic flow reactor
Robert L. Bedard,Christopher Naunheimer,Gavin P. Towler,Laura E. Leonard,Rodolphe Dudebout,Gregory O. Woodcock,Mittendorf Donald L +6 more
TL;DR: In this article, an approach for converting methane in a feed stream to acetylene is described. Butterfield et al. present an approach to convert at least a portion of the methane in the feed stream into acetylene by pyrolyzing it in a supersonic reactor.
Patent
Method of forming hollow channels within a component
TL;DR: In this paper, the authors proposed a method of forming an internal channel within an article, such as a cooling channel in an air-cooled blade, vane, shroud, combustor or duct of a gas turbine engine.
Patent
Method for manufacturing high performance components
TL;DR: In this article, a method for producing high performance components by the consolidation of powdered materials under conditions of hot isostatic pressure is proposed, using the inclusion of reactive materials mixed into pressure-transmitting mold materials and into the powder to contribute to in-situ materials modification including purification, chemical transformation, and reinforcement.

Method for fabricating a hollow component for a rocket engine
TL;DR: In this article, a method for making an engine component with a hollow interior includes the steps of: selectively patterning a principal substrate surface; forming a slurry including a selected amount of a binder material, a selected amounts of a solvent and a select amount of filter material; inserting the slurry into the substrate surface pattern; evaporating the solvent to solidify the slury; depositing a close-out layer of material over the patterned substrate surface and over the solidifed slurry; and without removing the closeout layer, removing the solidified slurry to provide

Infiltrated molded articles of spherical non-refractory metal powders
TL;DR: In this paper, a non-refractory metal article is made by molding in a flexible mold a plastic mixture of non-reractory, spherical metal powders and a heat-fugitive binder comprising thermoplastic material to form a green article of predetermined shape and dimensions.
Patent
Mold and process of making it
TL;DR: In this article, the process of manufacturing molds and dies is described. But the molds have been produced heretofore by electroplating models or articles of manufacture which it is desired to reproduce, stripping the electroplate from the model and employing the stripped electroplated form.
