Numerical Study of Active Flow Control on a Vertical Tail

摘要：

　　The application of active flow control on a vertical tail of a commercial airplane is investigated.The vertical tail uses a symmetry airfoil with 10%thickness and has a rudder at 33%of its chord.Blowing jet on the rudder is used and the effect is evaluated using the numerical methods.The in-house CFD solver named NSAWET is employed in the present calculations.Computational results show that,when the flow conditions are Ma∞=0.2 and Rec=6.5e6/m,active flow control with blowing jet of 错误!未找到 引用源.C μ=0.8%can effectively increase the side force by up to 5%,especially at the high sideslip angle when the flow is completely separated at the rudder surface.The principle is studied by side force coefficient,flow pattern,velocity contour and so on.
