Design team had done a ton of research into how wings are constructed both for general and ultralight aircraft. With a general understanding of the wing design and some starting variables from the physics team, the design team could start to lay their ideas down into Onshape, an online feature-based design program. At first, Justin figured out how to import an image into Onshape in an attempt to recreate the Clark Y profile with multiple splines. After a bit of research, however, Justin encountered the Aerofoil custom feature script, which allowed him to easily import the exact Clark Y profile. Ollie designed the ribs using circular weight reduction cutouts, but those may be updated later given info from Finite Element Analysis (FEA). We don’t have much experience designing wings so to make our design as adaptable as possible, Design Team has opted to use a series of independent variables to control the overall wing geometry. For example, we have a variable for wingspan, chord, angle of attack, etc… In the photo, the spars are sticking out of the ribs as we didn’t get to finish the dihedral variablization and it’s tweaking out a bit.
