Intial Design
This project mainly started during a Mechanics of Solids class. I have always been interested in the complex system of Fowler flaps. The system was designed with 12 links and modeled in CAD using Creo. The Fowler flap not only changes the camber of the airfoil but also allows for the extension of the wing.

The beauty of this design is how the complex motion of the fowler flap can be achieved by turing a single axel.Â

The entire design was created with the assumption that I would laser cut flat pieces of basswood for construction.
Stress Analysis of Simplified System
Stress Analysis of Simplified System
Using a simple analysis from Ansys and the assumption of an acting force, it is possible to identify the main areas that endure the most stress.

In this image, you can see the whole structure fully realized in basswood, along with a few 3D-printed components. The entire Fowler flap could be actuated using a geared servo motor on the main axle of rotation. This demonstration piece was a great stepping stone into the world of linkage mechanical systems.
