摘要
文章简要地介绍了两种民机空气动力先进设计技术的概念及其研究进展。一为层流流动主动控制技术。其核心措施是减弱流动的不稳定性,推迟转捩的发生,从而增大层流流动区域。目前混合层流流动控制方法发展比较充分,有望应用于未来民机的设计中。另一为新型非常规布局,包括翼身融合体、支撑机翼、吞吸机身边界层等新型气动布局,这些均有望大大提高未来民机的性能。
The concepts and the research on two kinds of advanced aerodynamic technology are briefly reviewed. One is laminar flow active control, which focuses on increasing the laminar flow region through decreasing flow instability and delaying the transition. A hybrid laminar flow control method has now been developed and probably will be used in future design. The other is a new type of aerodynamic shape, which can greatly increase the performance of commercial transport aircraft. Three new types of configuration——the blended wing body, strut-braced wing,and body boundary layer ingestion will be briefly described.
