研究采用合成射流代替传统吹气式环量控制翼型增升技术,将其应用于控制NCCR1510-7067N翼型的环量,采用商用软件Fluent求解二维非定常Reynolds平均NavierStokes方程组,通过分析零度攻角下翼型的气动力特性、漩涡结构等,研究了合成射流翼型环量控制的机制和效果.结果表明采用合成射流可以有效实现对翼型的环量控制,射流吹程和吸程均可以有效推迟翼型后缘分离点,增加翼型环量.在本文研究中,零度攻角下合成射流的增升效率C/C=114,远高于传统吹气式环量控制的增升效率12.1. In this paper, synthetic jets are used to replace traditional air-blowing annular control airfoil lift technology, which is used to control the ring volume of NCCR1510-7067N airfoil. The commercial unsteady Reynolds Navier-Stokes equations are solved by commercial software Fluent. The mechanism and the effect of synthetic jet airfoil loop control are studied.The results show that the synthetic jet can effectively control the airfoil ring volume, jet flow and suction stroke Can effectively delay the separation point of the trailing edge of the airfoil and increase the airfoil ring volume.In this paper, the increasing efficiency of the synthetic jet at zero angle of attack is C / C = 114, which is much higher than that of the conventional air blowing loop control Ascension efficiency 12.1.
