12:30 PM eVTOL design drivers, a reality check

This presentation explores the two key equations that govern the Vertical and Horizontal flight
phases of an eVTOL. In particular the importance of disc loading, lift-to-drag ratio and aircraft
battery mass fraction are discussed, comparing various winged and wingless eVTOL
configurations. This presentations also highlights the negative impact of complexity and excessive
redundancy on operational reliability.
• Understanding the two key equations governing take-off power and cruise range
• Vertical flight and the importance of a low disc loading
• Horizontal flight and the need for wings to achieve sufficient range
• The impact of redundancy on operational reliability
