Each folder is an airfoil project research. In each project, you will find the airfoil evolution. Airfoil coordinates and polar charts were made using my Digital Airfoil Designer software (DAD). Wind Chanel data came out from Drela Xfoil.
Example :
AMA 211001 RCSoaring (LD81.8 A1.4 R0.2 N9 T12.7 CL2.05)
AMA= acronym for Alan Mattanó Airfoil- AMA
21= the year when the project idea was created (in this case 2021) - AMA 21
10= Each year some projects are created. Project n°:1, n°2, this is project number 10 - AMA 2110
01= For each project, aerodynamic profiles are created in sequence with an internal number (last in evolution is better). - AMA 211001
RCSoaring= the airfoil general purpuse short desciption name. - AMA 211001 RCSoaring
(LD81.8 A1.4 R0.2 N9 T12.7 CL2.05)= airfoil characteristics (LD: maximum l/d efficiency at that Re,A: angle alpha of that LD,R: airfoil was design for Reynolds number,N: Ncrit turbulance value,T: Thickness percentage,CL: maximum lift coeficient at that Re).

AMA aerofoils were never tested in a real wind tunnel. The stalls can be very different from how they appear in the charts. Please be careful!
