Aerospace engineers interested in electric power. Electrical/mechanical engineers interested in VTOL aircraft. The content was 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. The content is aimed at a wide audience of mixed aerospace and non-aerospace background. A simplified multi-rotor VTOL aircraft was designed and analyzed in class, progressively, as an illustrative example. In the final module, historical eVTOL design case studies were reviewed, as well as comparisons of the pros and cons of various eVTOL configurations.

INSTRUCTORS
Anubhav Datta is a member of
the Alfred Gessow Rotorcraft Center (AGRC) and an Associate Professor of
Aerospace Engineering at the University of Maryland at College Park. He
holds a M.S. and Ph.D. in Aerospace Engineering from Maryland. He re-joined
AGRC as faculty in 2016 after nine years at the U. S. Army Aviation Development
Directorate (ADD) at NASA Ames Research Center. At Maryland, Datta and his
students are focused on future vertical lift barriers through Mach-scale
wind-tunnel tests and HPC-based high-fidelity simulations. The research
conducted by Datta and his colleagues have led to new fields in VTOL such as
Mars Helicopter (2000), CFD/CA (2004), and eVTOL (2012). Over the years his
work has been recognized by the VFS Grover E. Bell and Alfred Gessow Awards, NASA
Technical Excellence in Publications Award, and U.S. Army and NASA Group
Achievement Awards. Datta is the founder and inaugural chair of the VFS eVTOL
Technical Committee, Chair of the AIAA Structural Dynamics Sub-committee on
