A Technique for Measuring Unsteady Pressures.
Abstract
A system for measuring unsteady pressures in flow fields employing a remote transducer and thin plastic pressure transmitting lines has been designed and built. The static and dynamic characteristics of the system were determined experimentally. The measuring system was subsequently integrated into a two-dimensional wind tunnel model consisting of a symmetrical airfoil with a plain oscillating flap. The flap was harmonically oscillated, and the measuring system was used to determine both the steady and unsteady pressures at a point near the flap hinge line. The static and dynamic results were then compared to those obtained using thin airfoil theory. (Author)
