Owing to a renewed interest in advanccd-concept transport aircraft with active boundary-layer control (suction and/or blowing), a generalized multipoint method for the inverse design of airfoils with slot suction in incompressible potential flow is presented. Such a design tool could be used interactively to perform rapid trade studies to examine the potential payoff for boundary-layer control as applied to the advanced-concept wings. The method, which is based on conformai mapping, draws on the theory first published by Eppler and extended by Selig and Maughmer. The theory predicts an increased lift coefficient and a non-zero value for the drag coefficient as a result of the slot suction—a price to be paid for the increased lift. The theory also shows that this rion-zero value of the drag coefficient is exactly equal to twice the suction coefficient. Two examples are discussed to illustrate the method and the corresponding change in the aerodynamic characteristics of the airfoils as a result of slot-suction.
