The U.S. Defense Advanced Research Projects Agency’s (DARPA) Vulture program, which aims to develop and demonstrate technology to enable a single high-altitude unmanned airplane (UAV) to operate continuously for a period of five years, has entered phase II. Under the terms of an US$89 million contract, Boeing will develop a full-scale demonstrator called the SolarEagle that will make its first demonstration flight in 2014. The aircraft will have highly efficient electric motors and propellers and a high-aspect-ratio, 400-foot wing for increased solar power and aerodynamic performance.
