FLUCTUATING WIND GENERATOR, WIND TUNNEL TEST DEVICE USING THE SAME, AND FLUCTUATING WIND GENERATION METHOD

摘要

PROBLEM TO BE SOLVED: To allow a device configuration to be simplified and various tests to be efficiently conducted.;SOLUTION: A fluctuating wind generator arranged at an outlet at the upstream side of a measurement field of a measurement chamber to which air is supplied from an air blowing passage has: a plurality of blades arranged in a line in a direction orthogonal to air flow of the air blowing passage at the whole area of the outlet of the air blowing passage; a drive part for rotating the blades; and a control device for controlling the orientation of the blades to generate fluctuating wind regarding which air flow in the air flow direction and air flow in the direction orthogonal to the air flow fluctuate. Each of the blades has a symmetrical shape about the air flow direction as an axis.;SELECTED DRAWING: Figure 3;COPYRIGHT: (C)2018,JPO&INPIT
