PHOTOS: (Below) Once Boeing has proved the Phantom Eye demonstrator’s capabilities for high-altitude, long-endurance missions, a full-size variant of this unmanned aircraft system can be built for customers. Mission payloads could include intelligence, surveillance and reconnaissance sensors, Earth-mapping technology and other communications equipment that can play a crucial role in remote areas of the world or following natural disasters. (Opposite page, from top) Phantom Eye takes off from a special cart—the innovative design saves a considerable amount of weight, allowing the demonstrator to carry more fuel and payload; once airborne, Phantom Eye flew for more than five hours on this test flight and reached an altitude of 43,400 feet (13,300 meters). from other unmanned aircraft is its liquid hydrogen–fueled propulsion system. Liquid hydrogen has three times more energy than aviation fuel and burns more cleanly. The Phantom Eye engines leave only water vapor in the atmosphere. With a 150-foot (46-meter) wingspan, the Phantom Eye demonstrator can carry a 450-pound (200-kilogram) payload. A full-size version is expected to carry a 2,000-pound (900-kilogram) payload or stay aloft for up to 10 days. n james.a.wallace4@boeing.com For more about Phantom Eye see the April 2013 and July 2012 stories in Frontiers. 34 Frontiers August 2014
