现代战斗机非定常空气动力学及其风洞实验研究

Unsteady aerodynamics of modern fighter plane and experiment research in W. T.

良好的过失速机动飞行能力是现代战斗机的主要性能指标之一。本文描述了现代战斗机大迎角过失速机动飞行中存在的典型非定常气动现象、目前的研究水平和发展趋势；介绍了中国空气动力研究与发展中心低速所在该领域的研究现状，存在的不足以及下一步的重点研究方向。

Post stall maneuver is one of the main performance targets of the next generation fighter plane. This paper gives a brief description of typical unsteady through large angles aerodynamics phenomenon when modem fighter plane maneuvers of attack, the research level and perspective. The research situation of aircraft unsteady aerodynamics at high angle of attack in low speed aerodynamics institute CARDC has been presented also. At last the deficiency and research emphases in the future are given.
