__NOTOC__ The BAI Aerosystems (BAIA) BQM-147 Dragon unmanned aerial vehicle is a tactical battlefield UAV operated by the US Marine Corps. ==Development== The Dragon began life in 1986, when the US Marines Corps contracted with the Applied Physics Laboratory (APL), an offshoot of Johns Hopkins University in Baltimore, Maryland, that works on government technology development contracts, to build a small piston-powered UAV as an "expendable jammer" for battlefield electronics warfare. The program was logically named "ExJam". BAI Aerosystems was a subcontractor to APL and provided airframe parts. "Creeping featurism" infected the program as the Marines considered more applications for the little drone, and in 1987 the program was given the new name of BQM-147A "Expendable Drone" or "Exdrone". However, APL wasn't able to meet the schedule requested by the Marines for fielding the Exdrone, and so the program was passed on to BAI Aerosystems, with the Navy assisting by developing a video imaging system for tactical reconnaissance. The NASA Langley Flight Research Center also assisted in the development effort, performing wind-tunnel tests and making recommendations for aerodynamic improvements, and after these changes the BQM-147A Exdrone went into service with the Marines in time to help them chase the Iraqis out of Kuwait City. A few years later, the UAV-JPO also bought several hundred Exdrones for demonstrations and training to help get tactical officers in tune with battlefield UAV capabilities. The current "Dragon Drone" is an improved version of the Exdrone, obtained through a 1996 contract with the Marines. BAI renamed the UAV since the Exdrone wasn't really all that expendable, given that it carried a reasonably sophisticated sensor system and flight avionics. The Dragon Drone is a flying wing with a single tailfin that is symmetrically designed to allow it to fly with either side up. The Dragon Drone is powered by a small piston engine. It can carry one of three different plug-in turrets, featuring daylight color TV with a laser rangefinder, daylight color TV, or infrared imager. It can also be fitted with an auxiliary fuel tank for increased range. 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「BQM-147 Dragon」の詳細全文を読む スポンサード リンク
