本研究的目的是提供过失速翼型数据输入指南，用于使用叶素动量理论时预测峰值和峰值后转子功率。来自非定常空气动力学实验（UAE）转子试验的稳态数据集被用来为发展一种整体过失速方法提供指导，该方法用于预测将与2-D翼型数据一起使用的过失速3-D翼型特性。基于这些UAE数据，探讨了过失速区三维气动力的仿真方法。还建议进行实验测试，以便更好地理解三维流动物理学，并量化所需的理论或经验因素，以便采用全局过失速方法来支持叶素动量方法。
The objective of this study was to provide post-stall airfoil data input guidelines for the prediction of peak and post-peak rotor power when using blade-element momentum theory. A steady-state data set from the Unsteady Aerodynamic Experiment (UAE) rotor test was used to provide guidelines for the development of a global post-stall method for the prediction of post-stall 3-D airfoil characteristics to be used with 2-D airfoil data. Based on these UAE data, methods to emulate the 3-D aerodynamics in the post-stall region were explored. Also suggested are experimental tests needed to better understand the 3-D flow physics and to quantify needed theory or empirical factors for a global post-stall approach to support blade-element momentum methods.
