Abstract:

Fast response control technology has become one of the key technologies for hypersonic vehicle development. Plasma synthetic jet (PSJ), which is with fast response and synthetic characteristics, has initially shows excellent potential in terms of hypersonic flow control. A fast response hyper-vehicle control technology based on PSJ is proposed based on PSJ's fast response property and a simplified missile flow field control model for numerical study is established. Theoretical analysis of the typical structure of hypersonic missile flow shows that there are three characteristic flow structures. The PSJ actuators is arranged to these three characteristic positions and the effect on flow structure is observed, which results in the changes of the missile surface pressure distribution, as well as the characteristics of the lift, drag and pitching moments. Numerical simulation results indicate that the jet could have a significant influence on hypersonic flows. It makes the intensity of expansion wave and shock wave weaker, and has more significant effect on shock wave. The change of the flow structure and aerodynamic characteristics has a strong jet following character. That is to say, the flow change response time is very short, which is on the order of 0.2 ms. With rational layout of the actuators' position, quick change in the surface pressure distribution can be achieved for a missile, and thus modulating the missile's attitude can be realized.
