Report KD 333: “The Gö 711 airfoil modified as the Gö 711-12% and the Gö 711-10% airfoil —– is reviewed. The Gö 795, the Gö 796 and the Gö 797 airfoils are used for the modification procedure.The airfoil characteristics of these three airfoils were already given but a new table 2 is added which gives also the geometry of these three airfoils.
