The S414, slotted, natural-laminar-flow airfoil was designed for rotorcraft applications and has been analyzed theoretically using MSES and OVERFLOW. In addition, it has been verified experimentally in the Pennsylvania State University Low-Speed, Low-Turbulence Wind Tunnel. The primary objectives of the design are high maximum lift and low profile drag, both of which have been achieved while satisfying a thickness constraint. The theoretical analyses show good agreement with the experimental results. The experimental results are compared with those of the S406 and S411 airfoils, which were designed to similar specifications, and illustrate the potential benefits of the slotted, natural-laminar-flow concept.
