Wind tunnel equipment for environmental testing of automobiles

摘要

PPROBLEM TO BE SOLVED: To provide a wind tunnel device for an environmental test capable of performing an environmental test in an air flow similar to an actual moving state of a test vehicle even when a blowing air amount is small, miniaturizing a facility, and reducing operation cost. PSOLUTION: This device includes a wind tunnel chamber 11 having an air flow blowout opening 13 for blowing the air flow to the test vehicle 15, and a discharge port 14 for discharging the air flow passing around the test vehicle 15. The wind tunnel chamber 11 is provided inside with a portal induction duct 16 having an approximately rectangular section, provided extendedly in parallel with a blowout direction of the air flow from the air flow blowout opening 13; and a portal extension duct having an approximately rectangular section, arranged to cover the induction duct 17 and the front of the test vehicle 15 with an induction clearance 20 for generating induction wind 19b flowing along the outside of the air flow by inducing the air near the outside of the induction duct 16.
