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.
