摘要
进入21世纪,美军武器装备发展指导思想发生重大转变,放弃始于20世纪80年代基于敌对威胁的防御计划,转而实施基于敌对能力的防御计划,旨在发展和保持美国的航空、航天及信息优势。基于这一指导思想,美国空军2020年远景报告展示了美国空军未来作战概念,包括全球攻击,全球机动,全球持续打击,太空和C4ISR(指挥、控制、通讯、计算机、情报、监视和侦察),灵活作战支持。美国已针对这些作战任务所需的高速涡轮发动机、冲压发动机、超燃冲压发动机、脉冲爆震发动机、火箭发动机、组合循环发动机和极高效推进技术,开展了大量技术研究工作,并取得重大进展。特别需要关注高速涡轮发动机和超燃冲压发动机技术发展。
At the beginning of the 21st century, a significant change of the American force armament devel- opment rudder took place that the Department of Defense （DoD） determined to execute the capabili- ties-based planning rather than the former threats-based planning. The objective of the capabilities-based planning is to develop and maintain air, space, and information dominance on battlefields. Americas Air Force Vision 2020 is illustrative of the DoD capabilities-based planning process. It lays out the Air Force concept of operations （CONOPs）： global strike, global mobility, global persistent attack, space and com- mand, control, communications, computers, intelligence, surveillance, and reconnaissance （space and C4ISR）, and agile combat support. The missions require several propulsion capabilities： high speed turbine engine, ram/scramjet/PDE, rocket propulsion, combined cycle, and ultra efficient propulsion. Extensive re- search is already done in America. Great technology evolution is obtained.
