最近美国推出一种名叫“快鹰”(FASTHANK)的新式巡航导弹,它以其特有的作战性能和低廉的价格将取代“战斧”在巡航导弹家族中的霸主地位,成为21世纪美军继“战斧”导弹后的实施远程打击的重要武器。“快鹰”导弹采用的是环形头部进气道和推力矢量技术,最大射程超过1260公里,最小射程在92～111公里,速度在4倍音速以上,全程飞行需要8分钟。单价在50万美元以下。它的外形与“战斧”导弹的外形基本相似,推进系统是由串联式火箭超燃冲压发动机组成,使用的能量为释放率极高的碳氢燃料。采用一种梭镖式的气动布局,能使“快鹰”在高速度飞行状态下,保持良好的稳定性和打击精度。
Recently, the United States introduced a new type of cruise missile called FASTHANK, which will replace Tomahawk’s dominance in the cruise missile family with its unique combat performance and low prices. It will become the 21st century U.S. military successor “Tomahawk” missile after the implementation of long-range strike an important weapon. The Hawk missile uses a ring-shaped head intake and thrust vector technology with a maximum range of over 1,260 kilometers and a minimum range of 92 to 111 kilometers at 4 times the speed of sound. The full flight takes 8 minutes. Unit price below 500,000 US dollars. Its appearance and the “Tomahawk” missile shape is basically similar to the propulsion system is composed of tandem rocket scramjet engine, the use of high energy release rate of hydrocarbon fuel. The use of a kind of stinger-style aerodynamic layout, can make “Eagle” in the high-speed flight state, maintain good stability and strike accuracy.
