Short Course on Electric VTOL Technology

F74 eVTOL short course

Short Course Syllabus (PDF)

There has been a dramatic surge of interest in man-rated electric-Vertical Take off and Landing (eVTOL) aircraft in recent years — driven by advances in electric power and drone technology. Man-rated aircraft are more than drones; a safe, sound, and successful design requires a clear understanding of the underlying principles and technologies that enable this new class of aircraft. The objective of this course is to describe these principles and technologies. Session I is focused on the principles, in particular: aeromechanics of high disk loading props, trim and transient characteristics of VTOL aircraft, electrochemical power, and permanent magnet machines and drives. Session II is focused on technologies, in particular: NASA's integrated design tool for VTOL/eVTOL, detailed design examples, and flight-worthy power-train construction, integration and testing. Session I will equip the audience with the necessary background for Session II.

Led by Anubhav Datta from the University of Maryland, this multi-presenter course will provide an overview of the unique challenges and opportunities of this new class of vehicles. Both electric and hybrid-electric passenger carrying vertical flight aircraft will be covered for a variety of missions ranging from personal/private use to urban air taxis to regional electric VTOL bizjets.

Materials:
PDF copies of course notes will be made available a week prior to the Forum. You will receive an email with instructions on how to access your course notes. It is recommended (but not essential) that you bring the notes printed or downloaded on your laptop during the class.

Who should attend:
Aerospace engineers interested in electric power. Electrical / Mechanical engineers interested in VTOL aircraft. The content will be presented in a simplified and practical manner to allow innovators, entrepreneurs, and non-VTOL experts to be able to make useful calculations and build their own design / simulation tools.

About the Organizer:
Anubhav Datta is an Associate Professor of Aerospace Engineering at the University of Maryland at College Park. Prior to joining Maryland, he was at the U. S. Army Aviation Development Directorate (ADD) at NASA Ames Research Center for nine years (2007-2016), where he worked on full-scale rotor testing, aeromechanics code development, and eVTOL. Dr. Anubhav Datta (portrait) His current research in Maryland is focused on modeling and testing of new electric propulsion concepts for eVTOL and improving dynamic loads and stability of high-speed tilting prop-rotors through wind-tunnel testing and CFD/CSD simulations. He is the chair of the AHS Integrating Technical Team (ITT) on eVTOL, leads NARI's inter-city eVTOL working-group, chair of the AIAA Structural Dynamics Conferences Sub-committee, member of AHS Dynamics Committee, and an Associate Editor of the Journal of the American Helicopter Society. The research conducted by Datta and his colleagues have been recognized over the years by AHS's Alfred Gessow, Grover E. Bell, and Francois-Xavier Bagnoud Awards, NASA's Technical Excellence in Publications Award, and Group Achievement Awards from US Army and NASA.
