This year my research group had a good showing at the Acoustical Society of America, Dec. 2022. I was happy to give a 20 minute talk myself on jet and rocket coherence and loading. My student, Dr. Alex Carr, who is now a Research Aerospace Engineering at NASA reported on his sonic boom predictions. My M.S. student, Mr. Coelho, presented on his predictions of eVTOL configurations using reduced order modeling and the famous Ffowcs-Williams and Hawkings equation. My students presented a few short reseach papers. The presentations, abstracts, and citations are:
