Dynamic stall has been a technical challenge and a fluid dynamical subject of interest for more than fifty years; but in the last decade significant advances have been made in the understanding, prediction, modeling, and control of dynamic stall on rotors. This paper provides a summary of the state of the art of dynamic stall experiments and future directions in the understanding of dynamic stall on rotors. Experimental data sets are discussed, as well the direction of future research for control of dynamic stall. Coordinated testing between airfoils and rotating blades, as well as close integration between computational and experimental studies were found to be productive approaches. Advanced analysis methods, including statistical methods, modal representations, and artificial intelligence methods have led to significant advances in the understanding of dynamic stall. Investigations of dynamic stall control devices have allowed many useful targeted investigations of the transition to separated flow, but have not yet resulted in a commercially implemented device.

五十多年来，动态失速一直是一项技术挑战，也是一个令人感兴趣的流体动力学主题；但在过去十年中，在转子动态失速的理解、预测、建模和控制方面取得了重大进展。本文总结了动态失速实验的最新进展以及理解转子动态失速的未来方向。讨论了实验数据集，以及动态失速控制的未来研究方向。机翼和旋转叶片之间的协调测试，以及计算和实验研究之间的紧密结合被认为是富有成效的方法。高级分析方法，包括统计方法、模态表示法、人工智能方法使对动态失速的理解取得了重大进展。对动态失速控制装置的研究允许对向分离流的过渡进行许多有用的有针对性的研究，但尚未产生商业实施的装置。
