ABSTRACT:
A pressure distribution measurement system for measuring a pressure distribution on a measurement object. A flexible sheet-form pressure detection member includes a plurality of pressure passages extending in parallel and a pressure detection hole opened in each of the pressure passages is affixed to a surface of an outer plate of a main wing W of an airplane. Each of the pressure passages is connected to a pressure measurement device via a pressure pipeline. Because the pressure detection hole is opened in the pressure detection member, that is, the pressure detection hole is not required to be opened in the outer plate of the main wing, the outer plate is not damaged. Further, because the flexible sheet-form pressure detection member conforms well to the three dimensionally curved surface of the outer plate and has a small thickness, the airflow is hardly disturbed at all, thereby enhancing pressure distribution measurement accuracy.
