內容簡介Unmanned aerial vehicles (UAVs) are multiplying and evolving at an incredibly high rate. A noted aerospace research and consulting firm, The Teal Group (Fairfax, Va.), pegs 2008 worldwide expenditure for UAVs at 3.4 billion dollars (USD) and says it's the most dynamic sector of the aerospace market. The explosive growth encompasses systems large and small, including "micro" air vehicle (MAV) concepts less than 1 ft/305 mm in length. MAVs have generated interest in many sectors, both military and civilian, because of a shift in war fighting and policing strategy. Instead of putting soldiers or law enforcement personnel in harm's way, the new trend is to field an unmanned surveillance device, essentially a "man replacement" that can be considered a consumable, says Ernie Havens, chief engineer at Cornerstone Research Group (CRG, Dayton, Ohio). The company has developed a unique vertical takeoff and landing (VTOL) MAV system termed HALO, for Hovering Autonomous Low-profile Observer. HALO is designed to provide realtime sensing and surveillance in both outdoor and indoor environments and eventually could be deployed from an airplane in intelligent "swarms."
