description PROBLEM TO BE SOLVED: To provide a wind tunnel testing device capable of reducing power loss in air conveyance and reducing turbulent flow degree of a measurement chamber.SOLUTION: An absorption opening 6 is formed on an air duct wall 5w of an absorption air duct 5A, and an air-straightening frame 7 formed of an air-straightening blade 7a is formed in the front vicinity of an air collection port 4, and an outer peripheral part of air flow passing inside of the air-straightening frame 7 in view from an air flowing direction, is dissipated outside of the air collection port 4 via a gap between the air-straightening blade 7a and the air collection port 4, by a guide action of the air-straightening blade 7a. 【課題】空気搬送における動力ロスを低減しながら測定室の乱流度を小さくすることができる風洞実験装置を提供する。【解決手段】吸込風路５Ａの風路壁５ｗに吸収用開口６を形成するのに対し、集風口４の前方近傍箇所に整風翼７ａからなる整風枠７を形成し、この整風枠７の内側を通過する空気流の空気流れ方向視における外周部分を整風翼７ａの案内作用により、整風翼７ａと集風口４との間の隙間を通じて集風口４の外側へ逸散させる。【選択図】図３
