A design formulation is presented that incorporates aircraft performance considerations in the inverse design of low-speed laminar-flow airfoils for piston engine driven propeller-powered airplanes. Two aircraft performance parameters are considered: level-flight maximum speed and maximum range. It is shown that the lift coefficient for the lower and upper corners of the airfoil low-drag range can be appropriately adjusted to tailor the airfoil for these two aircraft performance parameters. The design problem is posed as a part of a multidimensional Newton iteration in an existing conformal-mapping based inverse design code, PROFOIL. This formulation automatically adjusts the lift coefficients for the corners of the low-drag range as required for the airfoil‐aircraft matching. The design formulation also has the capability to handle a constraint on the stall speed by automatically adjusting the wing area to account for changes to the airfoil maximum lift coefficient. Two examples are presented to illustrate the process for a general aviation aircraft, and the results are validated by comparison with results from postdesign aircraft performance computations.
