AeroVironment’s stratospheric Global Observer UAV makes first flight

Posted by John McHaleEDWARDS AIR FORCE BASE, Calif., 18 Aug. 2010. AeroVironment, Inc. (AV) (NASDAQ:AVAV) announced that the first unmanned aerial vehicle (UAV) developed under the Global Observer Joint Capability Technology Demonstration (JCTD) program completed its first flight. Global Observer Aircraft 1001 took off from runway 04L at Edwards Air Force Base (AFB) in California and climbed to an altitude of 4,000 feet where it performed a series of maneuvers before landing one hour later. The joint test team is preparing communications and intelligence, surveillance, and reconnaissance (ISR) payloads for aircraft integration. Once development flight tests are complete, payloads will be installed and joint operational utility flight demonstrations will be performed at Edwards AFB.AeroVironment's chief test pilot, Andy Thurling, a retired U.S. Air Force Lieutenant Colonel and former U.S. Air Force flight test pilot, operated the aircraft remotely from the portable Launch and Recovery Element (LRE). Thurling guided the UAV through a pre-determined flight path as the first step in a flight test campaign that will gradually demonstrate increasing flight endurance and operating altitude. The hybrid-electric aircraft flew for the first time under battery power and will ultimately carry a liquid hydrogen-fueled propulsion system to power it through high altitude, long endurance joint operational utility assessment planned for later in 2010. When flying in its battery-powered test configuration or in its liquid hydrogen-fueled operational configuration the air vehicle's propulsion system produces no carbon emissions.Each aircraft in a Global Observer system is designed to fly at an altitude of between 55,000 and 65,000 feet for five to seven days. In addition to flying above weather and above other conventional aircraft, operation in this altitude regime permits communications and sensor payloads on the aircraft to service an area on the surface of the earth as much as 600 miles in diameter, equivalent to more than 280,000 square miles of coverage. Equipped with payloads that are readily available today, two Global Observer aircraft would alternate coverage over any location on the globe every five to seven days, making this the first solution to provide customers with practical, seamless coverage, wherever and whenever required."This flight marks the beginning of an exciting new phase in the Global Observer technology demonstration program, and it represents a significant leap forward in the evolution of airborne communications and sensor platforms," says Tim Conver, AV’s chairman and chief executive officer. "In the 20th century conventional airplanes opened the lower atmosphere to practical use, and satellites did the same for space. I believe that Global Observer soon will establish the stratosphere as a valuable and practical area of operation."
