Abstract Scope |
This paper details continued work on small wings built with material extrusion. Two features have been added to a previously published in-house code developed for this application: (1) an experimentally derived constraint on internal structure to mitigate manufacturing-process induced skin deformation and (2) flanges on toolpath intersections to improve adhesion between wing skin and internal structure. Point clouds were taken of as-built surfaces to show mitigation of process-induced skin deformation. Bend testing was performed on wings built with and without the process improvements. The improved wings exhibit improved bending stiffness and reduced variability in bending performance. |
