Description
Quadrus Advanced Manufacturing, LLC (QAM) presents this proposal for the continued development of a W-24Re pintle with an integral lattice that simultaneously exhibits low effective thermal conductivity while maintaining positive structural margins. Our pintle design, which we have shown to be entirely feasible during Phase I, exhibits reduced effective thermal conductivity compared to a solid pintle at every temperature level while maintaining positive structural margins. At the conclusion of Phase II, QAM will have demonstrated an end-to-end AM process for fabrication a low thermal conductivity lattice-based W-24Re pintle that can withstand the harsh environment of solid rocket motor exhaust flow that has been proven through hot fire testing. More significantly, the cost of the component is driven by the amount of powder needed during the component’s fabrication, since no expensive post-build machining is required—this is a crucial factor when using an expensive refractory material such as W-24Re.
