| 摘 要： | 本文对人类升空奋斗史作了简要的回顾,指出人类虽然在飞行技术方面现已取得了惊天动地的成就,但有许多飞行技巧还远远不如飞鸟与昆虫;阐述了飞行器欲获得其升力的第二峰值之可能途径——对飞鸟与昆虫为获取其非定常涡升力的一些飞行奥秘作了剖析,在此基础上对当今空气动力学研究的一些方向性问題提出了一些见解,并就我国在这方面应当开展的研究工作提出了一些具体的建议。

| Abstract: | The history of mankind to struggle for lifting into thesky is briefly reviewed,and it is pointed out that although the mankindhas got earth-shaking achievement in flight technique,the flying skillof mankind is far from that of birds and insects in many aspects.Thepossible approaches for aircraft to get its second peak of lift areexpounded.the flying mysteries of birds and insects to achieve theirunsteady vortex-lift are analyzed.On the base of previous analyses someopinions on directive problems of current aerodynamics research are putforward;and specific suggestions for China ought to undertake in thisaspect are also given. |
