LHX《隐身》直升机主要用复合材料制成,以增加有效载荷和电磁隐蔽性(隐身性),它的任务是对付苏联直升机。它将在90年代中期取代越南战争时期的大批过时的直升机,共计7000多架。总的来讲,这是美国军队提出的5000架飞机的要求,这5000架飞机有两种类型(即武装直升机和侦察直升机)。飞机的速度可达314.8km/h,重量4.2～4.7t。飞机由两台T800涡轮发动机推进,每台推力为1200马力。目前T800的合同数至少达到10000台,两大工业集团一直参加了竞争,即加赛特、艾利逊、普拉特·惠特尼/阿芙科。另外,该发动机与已经安装在黑鹰直升机上的T700发动机相比,其特点是减少了60%的转动部件。
LHX Stealth helicopters are mainly made of composite materials to increase the payload and electromagnetic shielding (stealth), its mission is to deal with Soviet helicopters. It will replace a large number of outdated helicopters during the Vietnam War in the mid-1990s, totaling more than 7,000 aircraft. In general, this is the requirement of the 5,000-strong aircraft proposed by the U.S. military. There are two types of these 5,000 (helicopter gunships and reconnaissance helicopters). The speed of the aircraft up to 314.8km / h, weight 4.2 ~ 4.7t. The aircraft was propelled by two T800 turbine engines, each with 1,200 hp. At present the T800 contracts at least 10,000 units, the two major industrial groups have participated in the competition, that is, plus Dorset, Allison, Platt Whitney / Aveco. In addition, compared with the T700 already installed on the Black Hawk helicopter, this engine features a 60% reduction in rotating parts.
