In this course, participants learn about current development in electric and hybrid electric aircraft. Participants will learn how to design electric and hybrid electric aircraft starting from the top-level aircraft requirements. Design examples will include an electric air taxi and a hybrid-electric aircraft with distributed propulsion. Various powertrains will be examined including pure electric, parallel hybrid, serial hybrid, and combinations. It will be demonstrated which design variables are unique to electric and hybrid electric aircraft and how the sizing process of the powertrain components can be carried out.

Learning Objectives

  • Identify types of electric aircraft and current projects
  • Perform the preliminary sizing process of an electric or hybrid electric aircraft based on top-level aircraft requirements
  • Perform off-design mission performance analysis of sized electric and hybrid electric aircraft, with appropriate considerations of reserve requirements and battery life and safety margins
  • Perform trade studies on the fans, wing, and powertrain design variables to achieve a predefined design goal
  • Include aero-propulsive interaction effects into the preliminary sizing process by using results from experimental or numerical simulations

Who Should Attend

This course intended for engineers with a background in aerospace engineering that are interested in learning about the unique design considerations for electric and hybrid electric aircraft.
