Apparatus and method for controlling plasma flow at the trailing edge of an aerodynamic profile

摘要

A flow control method for a mobile platform (12), comprising: arranging at least one plasma actuator (16; 102) on a surface of the trailing edge (18) of a portion of a mobile platform; applying a voltage to said plasma actuator; and controlling said voltage for said plasma actuator to ionize air in an environment close to said plasma actuator adjacent to said surface of the trailing edge, to cause an induced flow adjacent to the surface of the trailing edge and characterized in that the induced flow flows selectively in the same sense as that of the flow of the boundary layer that flows over the plasma actuator or in the opposite direction to it, and operates by influencing the adhesion or separation of a boundary layer flow on said surface of the outlet flange depending on the direction in which The induced flow is caused to circulate.
