WALL SURFACE PRESSURE MEASUREMENT STRUCTURE AND WIND TUNNEL TEST DEVICE

摘要

To preferably measure an average value of a wall surface pressure even when a flow inside a duct is complicated.SOLUTION: In a wall surface pressure measurement structure for measuring a wall surface pressure inside an intake duct 31, a plurality of measurement holes 32 are formed at circumferential-direction positions different from each other on an inspection surface S orthogonal to an extension direction of the intake duct 31, in a wall surface of the intake duct 31. A chamber 33 communicating with each of the plurality of measurement holes 32 is provided on an outer circumferential side of the intake duct 31, and is connected with a pressure gauge 26 by one pressure pipe 25.SELECTED DRAWING: Figure 4
