Research Progress of hypersonic boundary layer transition control experiments

Abstract Hypersonic boundary layer transition is a hot yet challenging problem restricting the development and breakthrough of hypersonic aerodynamics. In recent years, despite great progress made by wind tunnel experiment, mechanism prediction, only partial knowledge has been gained so far. this paper, firstly, specific scenarios control are clarified. Secondly, experimental research passive active methods under different demands summarized, with their advantages disadvantages being analyzed separately. Plasma actuation easy to produce controllable broadband aerodynamic actuation, which potential in field control. Hence, following part paper focuses on plasma flow The feasibility demonstrated ideas presented. Finally, summarized direction future prospected.
