The invention discloses a hypersonic flow drag reduction structure, and relates to the technical field of hypersonic aircrafts. The hypersonic flow drag reduction structure comprises two or more independent small rib units arranged on the surface of an aircraft, and the small rib units are configured to be evenly arranged in the spanwise direction of the aircraft; wherein each small rib unit comprises a plurality of bionic microstructures arranged in the flow direction, and each bionic microstructure is obtained by constructing bionic grooves which are arranged in a V shape in space. According to the hypersonic flow resistance reduction structure, additional resistance is almost not introduced under the hypersonic flow condition, meanwhile, the wall surface friction resistance of the aircraft is reduced through flow control, and the hypersonic flow resistance reduction structure has a large engineering application prospect on hypersonic aircrafts.
