| Abstract: | A system based on a micro pressure sensor array was designed and established to measure pressure distribution of airfoil surface.Assembled onto a flexible polyimide substrate,the sensor array can be mounted upon airfoil surface easily.Related wind tunnel experiments were carried out.It shows this system can accomplish on-line measurement,real-time data processing and display,and has potential of dynamic pressure measurement of flow around non-planar surface.Measurement results with such system are coincident with those obtained through conventional pressure scan valve. |
