摘　　要：随着S弯进气道在先进战机的广泛应用,其诱发的旋流畸变也逐步引起研究人员的注意,为研究S弯进气道出口旋流场的特性,根据S弯进气道出口流场设计了旋流畸变发生器。结果表明:旋流畸变发生器可以精确复现目标流场,在气动交界面(AIP)上,旋流角的平均误差为1.12度;马赫数对旋流畸变发生器的影响可忽略不计;随着气流向下游发展,旋流强度变弱。With the wide application of S-shaped inlet in advanced aircraft,the swirl distortion generated by S shaped inlet has attracted more and more attention.In order to investigate the characteristics of the swirl distortion at the outlet of S-shaped inlet,we present a swirl distortion generator that enables simulate the swirl flow field at the outlet of S shaped inlet.The results show that the swirl distortion generator simulates the target flow field with high accuracy,and the error of the average swirl Angle on the aerodynamic interface plane(AIP)is 1.12°.The influence of the Mach number on the swirl distortion generator is negligible.With the development and mixing of the airflow downstream,the strength of the swirl decreases.
