Acquisition of Signals in a Wind Tunnel Using the Dasylab Software Package

This publication presents the use of the acquisition of signals in a wind tunnel using the DasyLab system to assess the suitability of selected airfoils for the power industry and is a presentation of their aerodynamic characteristics. Research experiments were carried out using the MCCOMPUTING USB 1608G modular measuring system. The publication is a description of the air profile using a prepared measurement system that allows obtaining the characteristics: polar profile as well as drag coefficient and lift coefficient depending on the angle of attack. The influence of wing mechanization on the characteristics describing the profile is also presented. The comparison of the profile analysed is presented publication and the profiles were compared based on the polar profiles, drag and lift coefficients as a function of the angle of attack of the profile. The DasyLab software was used for measurements and analysis.
