This paper describes a conceptual design process for natural laminar flow aircraft. A parameterized pressure distribution is added to existing multidisciplinary design tools, and a quasi-three dimensional boundary layer code with integrated transition prediction computes viscous drag. Natural laminar flow provides improved mission performance for a notional narrowbody aircraft.
