Bottom surface, side A, side B, leeward and inner surface；It is characterized in that, the leeward respectively with top surface, bottom surface and Nei Biao
Face arc transition；The windward side is respectively with top surface, bottom surface arc transition, and three faces are laid with bionical sharkskin drag reduction table
Face；The bionical sharkskin drag reduction surface is that multiple rows of and track moves towards consistent groove, and trench depth is all the same；The side A
Bionic super-hydrophobic drag reduction surface is laid with side B；The bionic super-hydrophobic drag reduction surface is that multiple row trend is moved towards with track
Vertical protrusion, the convex surfaces are a part of sphere.
It is 1:1 a further technical solution lies in the depth of, the groove and the ratio of width, the groove and groove
Spacing is all the same, and the ratio between spacing is 1:5 between groove width and groove.
A further technical solution lies in the depth and width of the groove are 0.2mm, and spacing is 1mm between groove.
A further technical solution lies in the ratio between the height of the protrusion and raised rounded bottom surface radius are 1:2.
A further technical solution lies in the height of the protrusion is 0.16mm, and the protrusion rounded bottom surface radius is
0.32mm。
A further technical solution lies in the adjacent two column protrusion is staggered.
A further technical solution lies in, the adjacent two column protrusions in the dislocation distance for moving towards vertical direction with track,
The distance ratio of distance is 1:2 between protrusion two neighboring in each column.
The invention has the following advantages over the prior art: the electromagnetism combined by designing two kinds of bionic, drag-reducing surfaces
Railgun armature can be effectively reduced suffered air drag in armature flight course, guarantee the stabilization of armature flight attitude, simultaneously
Improve the fire accuracy and range of electromagnetic railgun.
