BOUNDARY LAYER CONTROL DEVICE AND WIND TUNNEL TEST DEVICE USING THE SAME

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 【課題】各種試験を効率よく実行することができる境界層制御装置及びこれを用いる風洞試験装置を提供すること。【解決手段】送風路と接続され、前記送風路から空気が供給される測定室の測定領域よりも送風路側の床面に接続された境界層制御装置であって、測定室の測定領域よりも送風路側の床面に接続した吸い込みダクトと、吸い込みダクトと接続し、吸い込みダクトを介して測定室の空気を吸引する吸引機と、吸い込みダクトの床面側の端面の全面に配置され、複数の貫通孔が形成された吸い込み板と、を有する。貫通孔は、測定室の空気の流れ方向に並んで形成され、測定室側の表面の開口面積が、吸引機側の表面の開口面積よりも大きい。【選択図】図４
