The test results of winf tunnels are accessible to all databases. One of the most famous is the NACA.

Hundreds of Profiles are tested in wind tunnels. Some of these data are available on the Internet. ( mecaflux links)

In these databases you will find all the information necessary to determine the characteristics of a given profile.

you will find links on these data in tables that you will inserted it into the editor profiles mecaflux to calculate the lift and drag forces of your wings or foils:

Profiles, air foils Data and polar:

• UIUC Airfoil
• Polar data
• Which profiles are used for which airplanes?
• coordinate files of the profile format. dat files available for download:

Download List of coordinates Profile ZIP file:

• curves called Polar you give the coefficient lift and drag according to the impact profile and Reynolds number

  example of polar database profiles in the profile editor include in mecaflux:

The polar curves of lift and drag versus the reynolds numbers of the profile.

A sample of profiles is already built into MECAFLUX you only have to choose your profile

and set the speed, the fluid, the incidence, length chord of wing.

The lift and drag forces will be computed
