半个世纪以来,由于需求、技术和资金等因素的制约,吸气式高超声速飞行器技术的发展曾经历了多次起伏。早期的研究计划几乎全都无果而终。冷战结束后,对高超声速飞行器的需求发生了变化,高超声速技术的发展日益受到重视。到90年代,实现高超声速飞行器的首要技术——超燃冲压发动机取得了重大突破。随着高超声速技术的成熟,将可能对军事战略和军事行动产生重大影响。预计到2010年,高超声速巡航导弹将问世;2025年前,高超声速轰炸机
For half a century, the development of the technology of aspirated hypersonic vehicles has undergone many ups and downs due to the constraints of demand, technology and capital. Almost all of the early research projects ended without result. Since the end of the Cold War, the demand for hypersonic vehicles has changed. The development of hypersonic technology is gaining more and more attention. By the 1990s, a major breakthrough in the realization of hypersonic vehicles, the scramjet, was achieved. As hypersonic technology matures, it will likely have a major impact on military strategy and military operations. It is estimated that by 2010, hypersonic cruise missiles will come out; by 2025, hypersonic bomber
