5518.002 Design Guide for Scramjet Flowpath Features Fabricated via Large Format PBFAM

Rapid Large Area Metal Printer (RLAMP) can produce a full-scale scramjet flow path in fewer parts than current methods while maintaining high quality production of complex geometries.

Rapid Large Area Metal Printer (RLAMP) can produce a full-scale scramjet flow path in fewer parts than current methods while maintaining high quality production of complex geometries.

Metal laser powder bed fusion (LPBF) is beneficial to key aerospace and defense industries by enabling geometric designs otherwise impossible to achieve with traditional manufacturing methodologies. Additive manufacturing (AM) of scramjet components enables design freedoms, increased supply chain efficiencies, and enhanced DoD capabilities. Scramjet technology is already utilizing topological optimization combined with the flexibility afforded by AM to improve and innovate performance; however, small printers and unique scramjet features such as thin walls and complex channels limit deployment of AM for these components.
