An unnamed solar-electric aircraft that is capable of being in the air for a year has completed its maiden flight.
Built by BAE Systems subsidiary Prismatic, the Persistent High Altitude Solar Aircraft (PHASA-35) took to the air in South Australia for its first fully-integrated flight test.
The aircraft went from design to first flight in 20 months with two full-size prototypes completed in 2019.
Wingspan measure 115ft.
And its bespoke high-altitude propellers allow it to run against prevailing winds as it operates at altitudes of up to 70,000 FT.
More flight tests are planned for 2020, with initial operations to begin within 12 months.
