Abstract : Experience gained at British Aerospace (BAe) has shown that both Computational Fluid Dynamic (CFD) methods and experimental facilities play very important and complimentary roles in the design of modern military aircraft. The combination of theory and experiment gives a very powerful tool that has a significant impact on configuration design, allowing successful first time optimisation of aircraft shape. The main impact of CFD in configuration design is in allowing very rapid iterative refinement of aircraft shape. Effective use of CFD is accomplished by full integration into the design process through the development of Project Procedures. These procedures, aimed at specific, key aerodynamic design tasks, allow the engineer to: quickly analyse aircraft 3D Master Geometries and identify design modifications; easily obtain and quality assure the required data; and confidently estimate relevant aerodynamic data.
