PROBLEM TO BE SOLVED: To prevent adhesion of a particle to an inspection window and the like to reduce a total testing time by installing a partition plate dividing into a room including a particle generator and a room not including a particle generator in a space of an air storage tank. ;SOLUTION: A shock wind tunnel test equipment for testing a turbine stationary blade cascade and the like comprises a partition plate 115 placed so as to, for example, divide a space between an air storage tank 15 and an inlet of a testing part 14 into two spaces, and a particle generator 112 is installed in a particle feed tank 116 of a space at an opposite side of a camera 111. Then, a flow 119 including a particle 113 from the particle feed tank 116 is formed at a film breaking time to flow into the testing part 14. At this time, a flow 120 not including the particle 113 flows along a glass surface 16 at the side of the camera 111. Therefore, the particle 111 does not flow in a neighborhood of the glass surface 16, and adhesion of a particle to this surface hardly occurs. Moreover, the glass of the inspection window is made in a double structure, and high-temperature air is allowed to flow between the double structure to vaporize the particle 113 of polyhydric alcohol, etc.;COPYRIGHT: (C)2000,JPO
