This year, some of my students and collaborators are going to the AIAA SciTech conference in the DC area in the National Harbor, MD. We are presenting two particular papers. The first involves hypersonic flow-fields and the second involves acoustics and aerodynamic experiments. The citations, papers, and presentations are:

History of the Florida Aerospace Department
Professors Richard L. Fearn and Wei Shyy wrote a short history of my department [link] – Department of Mechanical and Aerospace Engineering at University of Florida. Previously, it was a stand-alone aerospace department that merged. It is worth reading and sharing if you have a connection to UF Aerospace. [link]
The prediction of cross-spectra from first mode instability waves within high-speed flow over sharp and blunt cones with plasma actuation
Abstract: Leading edge geometries, such as cones, moving at high-speed undergo intense loading due to the growth of instability waves and turbulent transition. These instability waves are highly spatially coherent. Aerodynamic loading related to instability waves and transition cause large-amplitude vibrations within the underlying structure, which may lead to flight-vehicle failure. We examine the effect …

On the On-Set of Hypersonics
Almost everyone has their own definition of the term hypersonic. If we were to conduct something like a public opinion poll among those present, and asked everyone to name a Mach number above which the flow of a gas should properly be described as hypersonic there would be a majority of answers round about 5 …
Aerospace Verses Mechanical Engineers
Mechanical Engineers use \(y\) as a coordinate axis at the ground pointing towards the sky. Dissimilar, Aerospace Engineers use \(y\) as a coordinate fixed to a flight-vehicle pointing towards the Earth. This is why Mechanical Engineers have their feet on the ground, and Aerospace Engineers have their heads above the clouds.
