A generalized automated data acquisition system was designed for the Naval Postgraduate School Aerolab Low Speed Wind Tunnel. A specific application of this system was to upgrade the current Cylinder Drag Experiment conducted during AA2801 Aero Laboratories 1 , an introductory aeronautical laboratory course taught at the Naval Postgraduate School. Two methods of drag determination were used pressure distribution and wake analysis momentum method. Data from these two methods were collected by a system based on a high speed analogdigital computer board, a standard 486 IBM-type PC and data acquisition software. Characteristic methods of reducing data from this experiment are discussed. The results obtained by analyzing the acquired data compared favorably to empirical data from previous circular cylinder coefficient of drag experiments. This automated data acquisition system will facilitate future research and instructional use of the wind tunnel.
