Patent number: 10808545Abstract: An embodiment of a fan blade includes an interior region between a metallic pressure sidewall and a metallic suction sidewall. Each sidewall extends in span from a base to a tip, and extends in chord from a leading edge to a trailing edge. The interior region of the fan blade includes a first fully dense metallic portion and a first porous metallic portion. The first fully dense metallic portion has a volume occupying at least 10% of a total volume of the interior region, and substantially no porosity. The first porous metallic portion is integrally joined to the fully dense metallic portion, and is selected from a structured lattice, an unstructured foam, and combinations thereof.Type: GrantFiled: July 14, 2017Date of Patent: October 20, 2020Assignee: United Technologies CorporationInventors: Tahany Ibrahim El-Wardany, Matthew E. Lynch, Om P. Sharma, Catalin G. Fotache
