Abstract

Flow control design of airfoil can induce airflow on airfoil surface by jet flow on airfoil surface, increase energy of boundary layer, and greatly improve drag generation and stall characteristics of airfoil. Common flow control methods include trailing edge circulation control, plasma induction, combined jet (CFJ) and so on. Current studies mostly focus on improving the lift-drag characteristics of airfoils under steady or unsteady conditions by various flow control methods. In this paper, a new flow control method of vector jet is studied. On the basis of improving the lift and drag characteristics of airfoil, the effect of control moment produced by vector jet is realized. The method is applied to the horizontal tail of a specific example aircraft to realize the longitudinal control and to explore its influence law. It is compared with the conventional elevator control method. It can provide guidance for future aerodynamic design and control rate design of rudderless aircraft.
