TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
This NASA sponsored STTR project will investigate methods for close-out of large, liquid rocket engine, nickel or stainless steel nozzle, coolant channels utilizing robotic laser and pulsed-arc additive manufacturing (AM)methods. Structural jacket to coolant channel land area interface strength will be quantified and metallurgical characterization completed. Process optimizations will be conducted to select best deposition parameters and starting feed stock for the AM processes based on article pressure drop and pressure testing. Sub-scale and intermediate size nozzles will be fabricated using the hybrid Metal Digital Direct Manufacturing (MDDM) processes and delivered to the NASA-MSFC for hot fire testing. Value stream analysis and process cost modeling methods will be used to estimate nozzle should costs and to identify relative economic risk of each nozzle AM operation.
POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Potential NASA applications include large liquid rocket engine combustion chambers and nozzles. Proposed process will enable elimination of current electrochemical plating methods for close-out of coolant channels in regeneratively cooled components utilized in liquid rocket engines. This technology has the potential to offer significant cost and time reductions for manufacturing of these types of compone4ts.
POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Potential Non-MASA applications include large liquid rocket engine combustion chambers and nozzles.
TECHNOLOGY TAXONOMY MAPPING (NASA's technology taxonomy has been developed by the SBIR-STTR program to disseminate awareness of proposed and awarded R/R&D in the agency. It is a listing of over 100 technologies, sorted into broad categories, of interest to NASA.)
