High-Altitude Long Endurance UAS Preps For First Flight
The Boeing Phantom Eye high altitude long endurance (HALE) UAS
completed 12 days of ground vibration and structural mode
interaction tests this month at NASA's Dryden Flight Research
Center at Edwards Air Force Base, CA. Phantom Eye is being prepared
for its first flight, scheduled for later this summer.
Phantom Eye's two hydrogen fuel tanks also were successfully
filled with nitrogen to test fueling procedures and the aircraft's
full-fuel weight configuration.
Phantom Eye has a 150-foot wingspan and is powered by two
2.3-liter, four-cylinder hydrogen engines that each provide 150
horsepower. It is designed to fly at 65,000 feet for up to four
days; perform intelligence, surveillance and reconnaissance
missions; and serve as a communications relay.
