基于一系列近似方法，对非定常翼型失速和失速颤振进行了分析。非定常气动力特性在理论上与静态气动力特性有关。初步结果表明，与实验动态失速数据吻合良好。分析应用于确定失速颤振的边界，特别是对于一个候选的航天飞机配置的直翼。如所述，分析应提供保守估计，即，与实验比较表明，预测的失速颤振区域略大于预期的失速颤振区域。
An analysis of unsteady airfoil stall and stall flutter is presented that is based on a series of approximations. Unsteady aerodynamic characteristics are related theoretically to static aerodynamic characteristics. Preliminary results show good agreement with experimental dynamic stall data. The analysis is applied to determine the boundaries for stall flutter, particularly for the straight wing of one candidate space-shuttle configuration. As formulated, the analysis should provide a conservative estimate - i.e., the predicted stall flutter region is slightly larger than the expected one, as demonstrated by comparison with experiments.
