System for acquisition and processing of pressure data around body in airflow

The paper deals with the system and methods for determination of the pressure distribution around aerodynamically shaped body immersed in airflow and further calculations of aerodynamic characteristics. Measurements are conducted in the subsonic closed-loop wind tunnel AT-1, in Aerodynamics Laboratory of Department of Aeronautics at Faculty of Transport and Traffic Sciences. Pressure distribution around airfoil NACA 2421 is sensed by the system for acquisition of pressure data Intelligent Pressure Scanner 9016, produced by the Pressure Systems company. Data are digitalized and transferred to the computer through the ethernet link. Data are processed by NUSS and LabView software. Measurement results are displayed and compared to those obtained from piezometric harp. Results of experiments are commented and recommendations for further research are given.
