PURPOSE:To perform the effective utilization on the installation floor surface of a wind tunnel test apparatus, by arranging a plurality of nozzles having different shapes to the storehouse provided under the floor surface of the wind tunnel test apparatus through a movable support stand and selecting the same by the nozzle replacement apparatus on the floor surface. CONSTITUTION:A lid 9 is detached and the measuring tunnel nozzle part 1a on a support stand 53 is moved to the point coinciding with the wind axis of a wind tunnel test apparatus by a hydraulic motor, a controller 50 and a ball screw 51. Next, the clamper 62 of a model replacement apparatus is opened on the basis of the indication of a controller 60 by the action of a hydraulic cylinder 5 to form a state capable of grasping the measuring tunnel nozzle part 1a. Next, the support 70 of the nozzle part 1a is grasped by the clamper 62 and the arm 61 of the replacement apparatus is rotated and moved to allow the nozzle part 1a to coincide with the wind axis. In this state, a wind tunnel test is performed and, in replacing the nozzle part in the next stage, the nozzle part 1a is detached by reverse procedure to be stored on the support stand 53 and the other nozzle part is attached to the wind tunnel test apparatus by the same procedure. |
