10:30 am - 11:00 am Architectural considerations for competitive electric aircraft

• Fixed wing, rotary wing, blown wing, ducts, articulations
• Flight from first principles
• Is weight the problem? (our answer will open doors for all!)
• Induced confusion, aka the controversial cost and familiar local optimums of negative buoyancy
• Energy in, momentum out: the only metric that matters?

12:30 pm - 1:00 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

3:00 pm - 3:30 pm The role of superconductivity in the evolution of the more/all electric aircraft

• The role of superconductors in future electric aircraft
• Conventional technology will struggle to meet the required power to mass ratios.
• Programs currently under way will demonstrate a step change in power to mass ratios for
superconducting machines
• All-electric aircraft equals more electrical power
• Power can be increased by increasing current and or voltage
• Higher voltages require new standards and voltages cannot be raised indefinitely.
Higher currents are provided by superconductors
