美国航空航天局（ＮＡＳＡ）一直在寻找一个能带动整个航空工业的大型研究计划，先是“革命性概念” 计划，包括翼身融合体／联合机翼运输机、主动气动弹性机翼、一种旋翼可以在飞行中被锁住成为固定翼的带有前翼／机翼的复合式飞行器和长续航时间的“蜂鸟”无人机等。现在又准备出台“２１世纪航空发展展望”规划，其中有“变形”飞机、“先进航空飞行器”等
NASA has been looking for a large research program that can bring the entire aviation industry to the ground. The first was a “revolutionary concept” program that included a wing fusion / joint wing transporter, active aeroelastic wing, a rotor wing A “hummingbird” UAV that has been locked in flight as a composite wing with a front wing / wing and a long wing as a fixed wing. Now it is ready to put forward the plan of “Prospects for Aviation Development in the 21st Century”, including “Transfiguration” aircraft, “Advanced Aviation Vehicle” and others
