原文文本 - English英语
In the 1990s, for example, the U.S. Air Force (USAF) and NASA jointly funded development of the Advanced Fighter Technology Integration/F-111 Mission Adaptive Wing (MAW), which was flapless and gapless. Boeing, the contractor, built a smooth-surfaced, variable-camber wing that could adjust its shape in response to flight conditions and pilot input to maximize aerodynamic efficiency. An internal mechanism flexed the wing skin to produce a highly curved section for subsonic speeds, a supercritical section for transonic velocities, and a symmetrical section for supersonic speeds. | 翻译文本 - Chinese汉语
上世纪90年代美国空军（USAF）和美国国家航空航天局（NASA）共同投资研发了一款无襟翼无缝隙机翼——先进战斗机技术整合F-111任务适型翼（MAW）。承包商波音公司制造的表面光滑、弧度可变的机翼可以根据飞行状况和驾驶员输入的信号来改变形状，以将气动效率最大化。一个内部装置可在亚音速状态下曲折机翼表皮以形成高曲率翼型剖面，在跨音速状态下形成超零界剖面，在超音速状态下形成对称剖面。 |
