'Dawn One' Flies As Part of Solar-Electric Hybrid Research Aircraft Program

Electra.aero has completed the first flight of a solar-battery hybrid electric research aircraft.

This 90-foot wingspan unmanned aircraft system (UAS) made its first flight from Manassas Regional Airport, Virginia on September 9, 2022, and is the first airplane to emerge from Electra's new development facility there.

The new plane, named Dawn One, is part of the Stratospheric Airborne Climate Observatory System (SACOS) program. SACOS is being developed under the leadership of Professor James G. Anderson at Harvard University. The project is supported by a contract from the National Aeronautics and Space Administration (NASA) and by the Weld Foundation for Scientific and Environmental Development.

"SACOS is designed to innovatively address a broad range of scientific missions and serve as a climate observing system that will herald a new era in the quantitative dissection of the physics, chemistry, and biology controlling critical climate systems. Following the lead of the new National Academy of Sciences report Global Change Research Needs and Opportunities for 2022-2031, SACOS promises to dramatically expand our national climate research capabilities," said Professor Anderson.

"The high-spatial resolution observations from SACOS will provide, for the first time, quantitative forecasts of risk associated with rapidly expanding wildfires, the increasing rate of sea level rise, the intensification of severe storms, and global shifts in arid regions that trigger water shortages.  Moreover, these quantitative forecasts of risk will, in turn, establish the essential intellectual links directly coupling irreversible changes in the climate structure to economics, public policy, and associated societal instability," Professor Anderson explained.

The Dawn One project originated at the Massachusetts Institute of Technology (MIT) led by Professors John Hansman and Mark Drela. Detailed design, construction, and testing of the aircraft were led by Electra.

This solar-battery aircraft is part of Electra's ongoing development of reduced and zero-carbon aircraft propulsion technologies, which also include turbine-electric and hydrogen fuel cell-based hybrid systems.
