Blowing and suction distribution system for drag and lift reduction and blowing and suction method

摘要

blunt object of the present invention is a two-dimensional shape (elongated in the longitudinal direction in the same section) fluids drag received by the flow (flow resistance to the flow) and lift (power in the vertical direction to the fluid flow), as for the system for reducing, preventing up and down due to the drop of the back pressure fluctuations occurring in the wake of the object injection device relative to the fluid injection is taking place in a given period; And a suction device takes place with a predetermined interval relative to the suction fluid; are alternately arranged side by side alternately in the longitudinal direction on the surface of the object a large drag force and lift force generated in the structure and having an elongated shape, so to transport body characterized in that said It was reduced by increasing the stability of the structure, transportation in a relatively small body effect of energy provided to the high energy efficiency by reducing drag and increasing the lift on the basis of understanding of the fluid flow around the elongated object to enable the fuel costs have.
