Abstract

A futuristic look at what should be pursued in terms of measurement instrumentation for aerodynamic research is presented. A cursory method is given for incorporating silicon microsensors, signal conditioning, and signal processing into a thin skin which will ultimately become the surface of an airfoil. Polyimide is the candidate material suggested for use as the skin because of its flexibility and IC processing compatibility. Specifications are given for the detection of boundary layer phenomena
