摘要
本文给出受迫谐振翼型的动失速工程估算方法。本方法基于凤洞试验，综合分析翼型动、稳态特性之间的差别与动、稳态条件之间的关系，建立一套估算动、稳态特性之间差别的经验公式，修正稳态特性，得到相应的动态特性。用本方法计算了三种翼型不同动态条件（包括深失速和后掠）的动失速特性，并与测量和文献结果进行了比较，结果符合得相当好。
The synthesized method for forced oscillating airfoil is developed. It based on wind tunnel experimsnt, by synthesizing the relations between the difference of result of steady and dynamic experiment with the condition,set up the empirical formulations which from the condition to predicate the difference.Then modify the steady loads with the differencedetermine the unsteady loads.This paper predicates three types airfoil dynamic stall with different conditions(include deep stall and swept).The result compared with test and reference is especilly agreeable.
