You can still see the remnants of the grid on the prints. Somers December 1993 ABSTRACT A family of thick airfoils for 3- to 10-meter, stall-regulated, horizontal-axis wind turbines, the S822 and S823, has been designed and analyzed theoretically. This makes the scale of the drag slightly different but the trends remain. Do you have any reliable source for the aerodynamics and geometry/settings of the airfoils for the full scale A-10?. 5 deg, the flow over the rough airfoil (left) separates and recirculates in the valleys between the rachis bumps, but beyond the biggest bumps it remains attached till the trailing. to increase the coefficient of lift.
