About the Instructor

Antonio Filippone is Professor of Computational Aerodynamics at the University of Manchester, where he has now served for over twenty years. He has published extensively on aerodynamics and related subject, and is the author of 3 textbooks, 10 book chapters, 75 peer-review Journal papers, 80 international conference papers and many technical reports for industry and sponsors. Over the past 15 years he has developed, with some of his associates, the computer code FLIGHT-X, which can simulate the complete environmental emissions from modern aircraft (both acoustics and chemical species from aero-engine combustion).  Further information is found on the web has his institutional website (, on Google Scholar, ResearchGate, LinkedIn. A compendium of the FLIGHT-X code is available with the most recent edition of his flight performance book, available directly from the AIAA.
