摘要
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.
