The goals of the UIUC Low-Speed Airfoil Tests (UIUC LSATs) program are to design, analyze and wind tunnel test airfoils for low Reynolds number applications. ![]() Thesis by John Brandt and following tests The propeller database includes three volumes: This webpage includes wind tunnel measurements for propellers used ![]() Sample profiles are already integrated in Mecaflux, you just have to choose your profile.John B. Curves, called polar, give you the coefficient of lift and drag, depending on the incidence (attack angle) of profile and the Reynolds number.Įxample Polar found in the databases of profiles data dat format available for download:ĭownload List profile coordinate ZIP file:Ĭoordinate files ( sample file, profile coordinate) allow to draw precisely the profiles. Which profiles are used to which aircraft ?.You will find the links below, the data in tables that can be inserted in the profile editor mecaflux to calculate their lift and drag: In these databases you will find all the information necessary to know the characteristics of a given profile. Hundreds of profiles have been tested in the wind tunnel. One of the most famous is the NACA airfoil database. The wind tunnel test results are available in databases.
