自40年代直升机问世,尤其是60年代投入实战以来,直升机以其独特的垂直起降能力、较强的机动能力、火力和突击能力在多次局部冲突中屡建奇功,引人注目。但与固定翼飞机的飞行速度相比,存在着明显的差距。为了克服传统旋翼的先天不足和着眼于未来飞行速度更新、机动性更好的新一代武装直升机设计,以美国为首的世界军事强国近年来进行了新概念直升机研制,并取得了引人注目的长足进展。 Since the helicopters were launched in the 1940s and especially in the 1960s, helicopters have made remarkable achievements and successes in many local conflicts for their unique capabilities of vertical take-off and landing, strong maneuverability, firepower and surprise capability. However, compared with the fixed-wing aircraft flight speed, there is a clear gap. In order to overcome the inherent shortcomings of the traditional rotorcraft and to design a new generation of armed helicopters with better maneuverability and flying speed in the future, the world-class military power headed by the United States conducted a research on new concept helicopters in recent years and made remarkable strides .
