The wind tunnel test results are available in databases. One of the most famous is the NACA airfoil database. Hundreds of profiles have been tested in the wind tunnel. In these databases you will find all the information necessary to know the characteristics of a given profile.

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: Profiles and polar data: Coordinate files (sample file, profile coordinate) allow to draw precisely the profiles. Curves, called polar, give you the coefficient of lift and drag, depending on the incidence (attack angle) of profile and the Reynolds number. example Polar found in the databases of profiles data

Sample profiles are already integrated in Mecaflux, you just have to choose your profile,...

and set the speed, the fluid, the incidence and length of the kite chord or rudder to obtain the lift and drag generated:
