Study on Flow Mechanism of Circulation Control Flap System

  • 摘要: 环量控制襟翼系统作为一种先进的襟翼系统,能够提高飞机起飞着陆性能并减小系统的复杂程度。以一种襟翼偏转角为60°的环量控制襟翼系统作为几何模型,采用Fluent求解定常雷诺平均N-S方程组,研究了不同动量系数时的环量控制襟翼系统的升力特性以及环量控制对流动分离的控制效果。计算结果表明:当攻角为0,动量系数为0.05时,ΔCl=1.7,效费比ΔCl/ΔCμ=31.4;随着动量系数增大,环量控制襟翼系统能够有效控制大偏角襟翼后方的流动分离,并在引射作用下使翼型上表面的流动速度加快,翼型环量增加,从而有效提高翼型的升力系数。
