PROBLEM TO BE SOLVED: To provide a boundary layer control device capable of effectively executing various tests, and a wind tunnel test device using the same.SOLUTION: A boundary layer control device connected to a blowing passage is connected to a floor surface of a blowing passage side farther than the measurement area of a measurement chamber supplied with air from the blowing passage, and includes: a suction duct connected to the floor surface of the blowing passage side farther than the measurement area of the measurement chamber; a suction machine connected to the suction duct and sucking air of the measurement chamber via the suction duct; and a sucking plate arranged on the entire end surface of the floor surface side of the suction duct and formed with a plurality of through-holes. The through-holes are formed side by side in the flowing direction of air of the measurement chamber, and an opening area of the surface of the measurement chamber side is larger than the opening surface of the suction machine surface side.SELECTED DRAWING: Figure 4 |
