Use of Simplified Flow Separation Criteria for Slotted Flap Preliminary Design 770481
From experimental correlations of airfoil and flap pressure distributions, it is observed that flow separation is likely to occur when the canonical pressure recovery coefficient (Cpr) exceeds a critical value. A procedure is described for obtaining the Cpr parameter from modified inviscid analysis. The procedure has been applied to preliminary design studies of a new slotted flap to determine the influence of shape and location. Experiments are planned to evaluate the flap designed by this procedure.
