A turbulence-oriented resistance-reducing grid mesh plasma exciter comprises a high-voltage electrode (11), a dielectric layer (13), a low-voltage electrode (12) and an insulating substrate (14) from top to bottom, the high-voltage electrode (11) is in a staggered grid shape, the low-voltage electrode (12) is in an array square block shape, and the center position of each square block corresponds to the center position of each grid hole of the high-voltage electrode (11). The grid mesh plasma exciter solves the problems that a traditional flow control technology is large in machining difficulty, high in cost and complex in structure, and a common plasma exciter is limited in effective drag reduction wind speed range. The excitation intensity and the working mode of the plasma exciter are controlled by the electric signals, so that the self-adaptive adjustment of different environmental parameters is realized, and the intelligence is realized. According to the invention, friction resistance reduction and flow separation control are realized, and the performance of a military low-speed unmanned aerial vehicle can be greatly improved, including stall at a large attack angle, broadening of a flight safety boundary, improvement of a flight range and the like.
