In order to achieve effective drag reduction, a bionic structure with a circular arc groove was designed based on the dragonfly wing tubular vein structure. By comparing the drag reduction related parameters and turbulence characteristics in the flow field of the incompressible-plate prototype and the modified scheme, the influences of the design parameters of the bionic structure on the resistance characteristics of the flow field and the starting position of the boundary layer transition were determined. The results showed that the arrangement of the bionic structure, the geometric size parameters and the number of groove rows affected the flow field regularly. At the same time, it was also found that the groove spacing had a similar effect on the range of size less than or equal to the groove width. The arrangement of the circular arc groove structure with a 0.75 mm deep size scheme at the first 20% flow direction length region of the transition position introduced external disturbances, which made the original laminar boundary layer velocity profile fuller and the anti-interference ability further enhanced, thus delaying the transition. In this way, the laminar flow coverage area was increased to achieve effective drag reduction. Compared with the prototype, the ideal scheme can increase 10.75% of the flow direction length range covered by laminar flow, and reduce about 6.38% of the friction resistance.
