Abstract
A computer controlled data acquisition system utilizing hotwire anemometry has been designed, built and installed in the Naval Postgraduate School Low Speed Wind Tunnel Facility. All relevant wind tunnel data is obtained by the use of a computer guided Hewlett Packard data acquisition system and a Para-Scientific Pressure Computer. Two computer programs were written to coordinate hotwire system calibration with hotwire experimentation. An experiment, Wake Velocity Profile Analysis and Drag Coefficient Measurement of an Airfoil, was used as a vehicle to test the system. The final output of the data acquisition system, including graphical information, compared favorably with previous results from an older data acquisition system already in use. Drag coefficient output compared very favorably to data supplied by the National Advisory Committee on Aeronautics.
