A Method of Testing Two-Dimensional Airfoils

Abstract

The Naval Postgraduate School Aeronautics and Astronautics Department conducts research and development for the Navy's Unmanned Air Vehicle program. NPS currently lacks the capability of testing two-dimensional airfoils to obtain lift, drag and pitching moment coefficients. This thesis consists of the design and calibration of a method of measuring these coefficients using strain gages, and the method of obtaining purely two-dimensional flow over the airfoil. During the calibration process, two amplifiers were tested in an attempt to minimize system drift and to ensure repeatability during successive runs. These desired characteristics were not achieved, however. The final phase was to be validation of the design by testing an NACA 0012 airfoil and comparing measured airfoil data with established reference data. This final phase was not completed due to structural failure of the airfoil.
