Linkage Model and Animation:
Using Motiongen.io, we created a sample linkage that mimics a similar motion profile to our desired output. As shown in the orange line, it highlights the wing's trailing edge of interest.
Sample Linkage Movement Movement :
Below is a short video that shows a sample range of motion that could be used to create the desired path and angles of the fail design.

Positional Tracking of Trailing Edge Point with Relationship to Input Angle
This graph shows the pathing of our indicated trailing edge under the range of potential angles of attack we are considering. However, our best estimates for an optimal angle of attack to lie between 10 and 40 degrees.

Positional Tracking of Correlated Leading Edge Point with Relationship to Input Angle
Similar to the first graph, the second graph highlights the positional analysis of a poitn that directly correlates to the leading edge of the foil. The same input angle range is estimated around 10 - 40 degrees.
