256 - Flight Research at NASA Armstrong, Part 1: Subscale
Guest: Al Bowers, Cheng Moua, Matt Moholt Host: Markus Voelter Shownoter: Andy Joiner
As part of my trip to the US earlier this year I visited NASA’s Armstrong Flight Research Center at Edwards Air Force Base. I conducted six interviews over two days, the ones concerning subscale research (i.e., on model airplanes) are in this episode. We start with a conversation about flying wings in general and Prandtl-D in particular with Armstrong’s Chief Scientist Al Bowers. Next, we chat about flutter research and the X-56 with project lead Cheng Moua. Finally, we talk to Matt Moholt about his project, the Spanwise Adaptive Wing project.
