The approach to aircraft design has traditionally been based on wind tunnel testing with flight testing being used for final validation. CFD (Computational Fluid Dynamics) emerged in the late 1960's. Its role in aircraft design increased steadily as speed and memory of computers increased. Today CFD is a principal aerodynamic technology along with wind tunnel testing and flight-testing. State-of-the-art capabilities in each of these technologies are needed to achieve superior performance with reduced risk and low cost. This paper discusses the role of CFD in the aerodynamic development of high performance jets, as illustrated by the application to Bombardier Business and Regional Jets. Emphasis is put on the methodology, in particular the combination of CFD with targeted wind tunnel tests and flight test to arrive at optimal configurations.
