>综述
Bell407是一款主旋翼为4片桨叶、单发涡轮轴的轻型民用直升机,主要用来替代Bell206L4“远程突击队员”直升机。 Bell407采用全复合材料打造的4片主旋翼系统,其结构与美国军方使用的OH-58D类似。Bell407广泛应用于商务飞行、海上飞 行、应急救援、警务飞行、新闻采访、航拍等。
>技术特点
· 贝尔407直升机可实施垂直起落,左右横行、前进及倒退,并能在空中悬停和定点转弯等,因为其具有机身小、飞行灵活的特点,所以适合执行公务、医疗急救、抢险救灾、海洋作业、航拍等。
· 贝尔-407采用HTS-900新涡轴发动机,功率为680千瓦,发动机总重量增加到2.56吨。燃油装在两个互连的抗坠毁软油箱中,加辅助油箱,载油量比oh-58d有较大增加。它采用低噪声巡航系统,利用全权数字发动机控制系统把旋翼转速降低为巡航转速的90%~93%,从而降低了arh的通场噪声。
· 旋翼系统采用全复合材料4桨叶旋翼系统,其结构与OH-58D的类似,两片桨叶尾桨。机身与贝尔-206L-4“远程突击队员”的机身相似,但座舱增宽了0.178m,座舱窗户面积也增大了35%。采用碳纤维尾梁,座舱门窗是平板式的
· 贝尔-407采用单旋翼带尾桨布局,采用经过改进的OH-58D的4片桨叶旋翼、尾桨和减速器系统。机体防护有所改善。前机身包括驾驶舱和座舱,空间不拥挤,改善了乘坐舒适性。机身两侧舷窗面积比原型机增加了35%,安装特殊玻璃,增加了舱内采光,扩大了驾驶员和乘员视野。
>运行历史
· Bell made delivery of the first producIon 407 at Heli-‐Expo, in Dallas, Texas in February 1996. Launch customers for the aircraT were Petroleum Helicopters, Niagara Helicopters, and Greenland Air.
· On 23 May 2007, Colin Bodill and Jennifer Murray completed a record pole-‐to-‐pole around the world flight uIlizing a standard Bell 407. The flight originated from Bell's facility at the Fort Worth Alliance Airport on December 5, 2006. The team flew about 36,000 miles (58,000 km) over 189 days and 300 flight hours, through 34 different countries. The project, named Polar First, was performed in partnership with the Royal Geographical Society to provide educaIonal outreach to 28 internaIonal schools, which were visited during the trip. The project also served as a fundraiser for the SOS Children's Villages.
· In 2009 the Iraqi Air Force ordered three Bell 407 armed scout helicopters (similar to the canceled ARH-‐70).[14] A contract for 24 addiIonal Bell 407s with an opIon for 26 more was awarded in April of that same year.[15] The U.S. Army is managing modificaIons and installaIon of military equipment on the helicopters.[16] Three training T-‐407s were delivered to the Iraqi Army in 2010. Armed IA-‐407s were delivered in eight batches of three aircraT from August 2012 to April 2013. The final Bell 407 for Iraq was delivered on 3 April 2013.[17] There are 30 in service; 24 armed scouts, 3 gunships, and 3 trainers.

· Iraq is using the IA-‐407 in operaIons against Islamic State militants. On 8 October 2014, militants shot down an IA-‐407 using a shoulder-‐fired ground-‐to-‐air missile, killing the pilot and co-‐pilot.
· 200X年,Bell407民用版正式获得中国民航的适航认证(型号认证)
