NASA New Aviation Horizons Initiative
[one_third]
Distributed Electric Propulsion (DEP) is a new technology frontier, enabling ultra-high efficiency, low carbon emissions, low community noise, and low operating costs.
When coupled with the autonomy technology frontier, will enable transformative high-speed On-Demand Mobility

Cruise Motors
[note]
- Air cooled, direct drive outrunner
- Replaces 100 HP Rotax 912S engine with 60 kW Joby motor
- Expected cruise operating point between 42 and 45 kW
- Tailoring FAA engine design acceptance testing (Part 33) for NASA flight qualification
- Electrodynamics, thermal and control modeling and prototyping underway

Battery Module Configuration
[note]
- Electric Power Systems design
- Organized into 8 battery modules per aircraft, split into two packs, each with 4 battery modules and a control module
- Cooling analysis will drive module spacing, cells spaced at 4mm
- Nickel Cobalt Aluminum 18650 cells selected; provides sufficient energy density and discharge rate for SCEPTOR mission. Cells arranged in 20p32s modules with BEP between series halves.
- Each pack is 20p128s; 47 kWh useful capacity, 461 VDC nominal (416 to 525 across SOC range), peak discharge of 132 kW
- Will comply with flight environment, including 18 g crash loads, -5 to +45 °C operating environment

We’re at the beginning of a 30-50 years propulsion revolution
Electric propulsion is not merely about propulsion, it’s about being able to apply a scale-free technology to fundamentally change how we design vehicles. Synergistic integration of Distributed Electric Propulsion will transform aircraft, and the missions they perform, and potentially society
The age of on-demand services is about to lead to On-Demand Mobility
