美国自20世纪50年代开始研究吸气式高超声速技术。冷战期间,美国出于军备竞赛和争夺技术领先的需要,提出过许多超燃冲压发动机及高超声速飞行器发展计划,如先进战略空射导弹(ASALM)、超燃冲压发动机导弹(SCRAM)、高超声速研究用发动机计划(HREP)、国家空天飞机计划(NASP)等。这些计划虽均中途夭折,但在关键技术方面取得了重大突破,大大推动了美国高超声速技术的发展。仅美国航空航天局兰利中心在
The United States has been studying aspirated hypersonic technology since the 1950s. During the Cold War, the United States proposed many plans for the development of scramjet and hypersonic aircraft for the purposes of arms race and competition for advanced technology. For example, Advanced Strategic Air-to-Air Missile (ASALM), Scramjet (SCRAM), Hypersonic Research Engine Program (HREP), National Space Shuttle Program (NASP) and others. Although all of these plans died midway, major breakthroughs were made in key technologies and greatly promoted the development of hypersonic technologies in the United States.
