Hydrogen-Powered UAS Can Stay Aloft For Up To Four Days At
FL650
The hydrogen-powered Phantom Eye unmanned airborne system, a
demonstrator that has the ability to stay aloft at FL650 for up to
four days, was unveiled by Boeing on Monday.
Phantom Eye
"Phantom Eye is the first of its kind and could open up a whole
new market in collecting data and communications," Darryl Davis,
president of Boeing Phantom Works, said at the unveiling ceremony
in St. Louis. "It is a perfect example of turning an idea into a
reality. It defines our rapid prototyping efforts and will
demonstrate the art-of-the-possible when it comes to persistent
intelligence, surveillance and reconnaissance."
Later this summer, Phantom Eye will be shipped to NASA's Dryden
Flight Research Center at Edwards Air Force Base, CA., to begin a
series of ground and taxi tests in preparation for its first flight
in early 2011. That debut flight is expected to last between four
and eight hours.

"The program is moving quickly, and it's exciting to be part of
such a unique aircraft," said Drew Mallow, Phantom Eye program
manager for Boeing. "The hydrogen propulsion system will be the key
to Phantom Eye's success. It is very efficient and offers great
fuel economy, and its only byproduct is water, so it's also a
'green' aircraft."
Phantom Eye is powered by two 2.3-liter, four-cylinder engines
that provide 150 horsepower each. It has a 150-foot wingspan, will
cruise at approximately 150 knots and can carry up to a 450-pound
payload.
