The invention relates to the technical field of active resistance reduction of underwater navigation bodies, in particular to a self-adaptive control resident type microbubble array flow resistance reduction device which comprises a base body and a direct-current power source, the base body is electrically connected to a negative electrode of the direct-current power source, and a positive electrode of the direct-current power source is communicated with external water flow. A plurality of cylindrical electrode wall surface micro-pits are uniformly formed in the upper surface of the base body, the wall surfaces of the electrode wall surface micro-pits are covered with metal layers, and an insulating paint layer is laid on the upper surface of the base body. The diameter of the micro-pit on the wall surface of the electrode is 200-300 microns, and the depth of the micro-pit is 100-150 microns. According to the scheme, the motion resistance of the underwater navigation body is effectively reduced in a self-adaptive residing type micro-bubble resistance reduction mode, and manufacturing and implementation are easy; the prepared resident type microbubbles can be spontaneously supplemented in the movement process, and have excellent stability and self-adaptability. The invention further provides a preparation method of the resident microbubble array flow resistance reduction device, the process is simple and convenient, and the adhesion degree is high.
