The turbulence friction resistance reduction device based on array type corona micro-blowing comprises a corona discharge cavity plate (1) and a discharge electrode (2). A plurality of cylindrical inclined micro holes are formed in the front face of the corona discharge cavity plate (1) and serve as corona discharge anodes, the cylindrical inclined micro holes are distributed in the front face of the corona discharge cavity plate (1) in an array mode, and the inclined directions of the cylindrical inclined micro holes are changed in a staggered mode. The high-voltage direct-current power supply (4) generates direct-current high voltage and applies the direct-current high voltage to the discharge electrode (2), plasma (6) is generated between the discharge electrode (2) and the corona discharge cavity plate (1), two oblique jet flows of each discharge group are coupled to form spirally-rising jet flows, a normal blowing effect is generated in a flow field, and turbulent friction resistance reduction is achieved. The invention further provides a turbulence friction resistance reduction device and method based on array type corona discharge. The sensor is arranged in a flow field to collect flow field data, the flow field state is sensed in real time, the corona discharge mode is controlled, the optimal resistance reduction effect is kept in the rapidly-changed flow field state, and the resistance reduction adaptability is further improved.
