The Boeing Insitu ScanEagle is a small, long-endurance unmanned aerial vehicle (UAV) built by Insitu, a subsidiary of Boeing.〔 (mirror )〕 The ScanEagle was designed by Insitu based on the Insitu SeaScan, a commercial UAV that was intended for fish-spotting. The ScanEagle continues to receive improvements through upgrades and changes. ==Design and development== ScanEagle is a descendant of another Insitu UAV, the Insitu SeaScan, which was conceived of as a remote sensor for collecting weather data as well as helping commercial fishermen locate and track schools of tuna. ScanEagle emerged as the result of a strategic alliance between Boeing and Insitu. The resulting technology has been successful as a portable Unmanned Aerial System (UAS) for autonomous surveillance in the battlefield, and has been deployed since August 2004 in the Iraq War. ScanEagle carries a stabilized electro-optical and/or infrared camera on a lightweight inertial stabilized turret system, and an integrated communications system having a range of over ; it has a flight endurance of over 20 hours. ScanEagle has a wingspan a length of and a mass of 〔(【引用サイトリンク】title=ScanEagle System )〕 and can operate up to , with an average cruising speed of .〔 Block D aircraft featured a higher-resolution camera, a custom-designed Mode C transponder and a new video system. A Block D aircraft, flying at Boeing's test range in Boardman, Oregon set a type endurance record of 22 hours, 8 minutes.〔"Boeing ScanEagle achieves major flight milestones", ''Aerotech News & Review'', November 23, 2006.〕 ScanEagle needs no airfield for deployment. Instead, it is launched using a pneumatic launcher, patented by Insitu, known as the "SuperWedge" launcher. It is recovered using the "Skyhook" retrieval system, which uses a hook on the end of the wingtip to catch a rope hanging from a pole. This is made possible by high-quality differential GPS units mounted on the top of the pole and UAV. The rope is attached to a shock cord to reduce stress on the airframe imposed by the abrupt stop. Each ScanEagle system costs US$3.2 million (2006).〔 A complete system comprises four air vehicles or AVs, a ground control station, remote video terminal, the SuperWedge launch system and Skyhook recovery system. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Boeing Insitu ScanEagle」の詳細全文を読む スポンサード リンク
