Add to ORKGA wind tunnel test was conducted on a twodimensional model of the NACA 0012 airfoil section with either a conventional solid upper surface or a porous upper surface with a cavity beneath for passive venting. The purposes of the test were to investigate the aerodynamic characteristics of an airfoil with full-chord porosity and to assess the ability of porosity to provide a multipoint or self-adaptive design. The tests were conducted in the Langley 8-Foot Transonic Pressure Tunnel over a Mach number range from 0.50 to 0.82 at chord Reynolds numbers of 2 × 10 6, 4 × 10 6, and 6 × 10 6. The angle of attack was varied from −1 ° to 6 ° in 1 ° increments. The porous surface nominally extended over the entire upper surface. The porosity was zero at...
