Abstract

With the increase in additive manufacturing capabilities the use of 3D printed models characterize a critical point for evaluating aerodynamic and aeroelastic properties on aircraft configuration. An experimental and computational approach beginning with elastically scaled 3D printed models enables for a case to be defined, developed, and extracted to match aeroelastic test behavior. The basis of this work is supported by aeroelastic tailoring and scaling methods in the application of 3D printed models. To accomplish this, stiffened 3D printed plates are scaled from elastically scaled 3D printed models for stiffness through geometric configurations, different build orientations, and bead thickness as the driving factors. The methodology developed in this case study shows that build orientation has a considerable effect on stiffness but, not as significant as build configuration and bead thickness. This is seen throughout all 3D printed plates that were printed along the ZX axis 0° orientation instead of the ZX axis 45°orientation. However, the 3D printed models with the 45° configurations had a significant decrease in stiffness when printed at a 45° orientation. This means printing in the ZX axis with zero orientation results in the highest overall stiffness. The methodology is presented such that stiffness tuning and tailoring can be calibrated for variations in the design.
