WASHINGTON — The Air Force has begun constructing its first station to recharge electric aircraft, marking its latest step in experimenting with non-fuel burning helicopters.
The service broke ground on the charging station at Duke Field in Florida Sept. 19, the Air Force Research Laboratory said in an announcement, and it’s going to be the primary electric aircraft charging station on a military installation. AFWERX, the service’s unit that focuses on innovation, and Burlington, Vermont-based electric aerospace firm Beta Technologies are constructing it.
Beta Technologies is certainly one of greater than a dozen firms with contracts through the Air Force’s Agility Prime program, a three-year-old effort that goals to speed up industry’s work on creating and fielding electric vertical-takeoff-and-landing aircraft.
The Duke Field charging station is scheduled to be finished by Oct. 13. Beta is predicted to deliver its ALIA eVTOL aircraft to the bottom for testing in early fall. Duke is 10 miles north of Eglin Air Force Base, and is home to the 413th Flight Test Squadron, which tests rotary wing aircraft for the service.
The station could have a Level 3 supercharger developed by Beta, and is predicted to have the opportunity to recharge an eVTOL in under an hour using DC current. Level 3 chargers are the sort typically installed in electric vehicle stations in malls, parking garages and other public areas.
“If you desire to make [electric aircraft] viable from a industrial or military perspective, I can’t wait 24 hours to charge my airplane,” Maj. Riley Livermore, the squadron’s flight commander, said within the Air Force’s statement. “They should do it in lower than an hour.”
But a quick charger like this requires an incredible amount of power — enough to supply electricity for 250 homes, Livermore said. So the bottom upgraded its electric grid with a 1000 kW transformer to supply the high-power current needed to quickly charge aircraft on the 480-volt, 400-amp station, he said. The brand new transformer can raise or lower a current’s voltage and intensity as needed while keeping the electricity flow regular.
Maj. Anthony Zartman, the pinnacle of the Agility Prime program, said the service’s experimentation with eVTOL craft is progressing right into a latest phase.
“We’ve grown to the purpose now with our partners that we’re able to put hardware at multiple bases and take an in depth take a look at possible use cases,” Zartman said.
The Air Force is considering dozens of potential uses for electric aircraft, from rapidly transporting cargo or passengers around a base to search-and-rescue missions in combat. EVTOL aircraft are much quieter than traditional fuel-burning helicopters, and value less to operate and maintain.
Joby Aviation delivered the Air Force’s first eVTOL to Edwards Air Force Base on Sept. 25. In an interview before the delivery, an Air Force official said the Joby aircraft would first be flown remotely, and later flown by human pilots in its cockpit.
Joby said in a Wednesday release 4 of its own test pilots have now accomplished flights in its air taxi at its Marina, California, pilot production facility. These tests included free thrustborne hovers and forward transitions to semi-thrustborne flight, the corporate said, and can complement Edwards’ own flight tests using the aircraft for day-to-day tasks.
