In the Aeroelasticity Lab, we have designed a flutter test for aeroelasticity students. Following loading and ground vibration tests, the students received the wing’s structural data to determine the flutter onset speed. Today, we tested the wing in the department’s low-speed wind tunnel, leading to a dramatic (but with a happy ending!) flutter demonstration.

Had the honor and pleasure of participating in a workshop on high aspect ratio wing technologies, at the Brahmal Vasudevan Institute for Sustainable Aviation at Imperial College London, organized by my talented colleagues Prof. Rafa Palacios, Prof. Carlos Cesnik, and Dr. Markus Ritter. Over two intensive days, we’ve heard about challenges and possible approaches to flexible high aspect ratio wings that will make the next-generation transport aircraft platforms. 

Here is a link to the workshop website, with super interesting presentations from academia, research organizations, and the industry,  and a link to my talk on our design, analysis, and testing of the very flexible Pazy aeroelastic benchmark wing.
