Secondary Correction Formula for Two-Dimensional Lift Coefficient Measured in a Wind Tunnel

An improvement of the secondary correction formula for the lift coefficient of an airfoil measured in a wind tunnel is presented, taking into account upwash and blockage effects. The formula allows the extension of the limits of correctability in the presence of strong variations of wall-induced vel...
