Timothy Takahashi, Associate Professor
Professor Takahashi brings many years of industrial and government experience to his research interests in aircraft performance, aerodynamic design and flying qualities. He has worked at NASA/Ames Research Center both as an NRC Postdoctoral Fellow in the Low Speed Aerodynamics Group and as a Legal Intern in the Office of General Counsel. He has also held senior and principal engineering positions at Lockheed Martin, Northrop Grumman and Raytheon. For the 13 years prior to joining AFIT full time, he was the Professor of Practice in Aerospace Engineering at Arizona State University. He is the author of a two-volume book on Aircraft Performance & Sizing, traditional engineering journal papers, three law review papers and, along with his many students and collaborators, nearly 200 scholar.google indexed archival conference papers. He is a member of Phi Beta Kappa, Tau Beta Pi and is an Associate Fellow of the AIAA. He is active with both the AIAA Aircraft Design and the History Technical Committees.
