Model Design

Model Design Week 1


One of the primary goals of our process is to have a scale model to test the flight characteristics of our plane before it actually gets constructed. This scale model will be remote controlled. Constructing this model is not as simple as just scaling down all parts of the plane and calling it a day. We need to find materials that will effectively mimic the characteristics of their full-scale counterpart, which is no easy task. On one hand, they need to have the same shear, tensile, torsional, and yield strength when scaled. The materials chosen will also need to be similar densities to distribute weight accurately to the full-scale craft. In order to compare characteristics, we first needed to determine scale for our model. the scale of 1′ = 1″ was chosen, as although it is slightly larger than most standard scaling choices, it will allow us to create a more detailed and therefore more accurate representation of our final craft. After some initial research, several common materials were recorder for further analysis. These include carbon fiber, aluminum, silk, aerokote, koverall, modeling tissue paper, depron, styrofoam, e-glass, epoxy resin, and acrylic.
