Abstract:

Now one of the most important factors of a successful civil aircraft design is applying computational fluid dynamic (CFD) numerical methods and software, especially the design tools, to the design. In the present paper, historic development and application of the inverse design concept and numerical optimization methods based on low and high fidelity models are described briefly. The International Aerodynamic Optimization Design Computation Workshop, which will be held soon, is introduced. Optimization methods of design based on the Navier-Stokes solver are discussed in detail, including the requirements to them and their construction issues. Numerical examples of OPTIMAS applying to a wing-body fairing shape design and a blended wing body (BWB) shape design have shown the efficiency of OPTIMAS for use as a daily design tool for civil transport design.

Key words: civil aircraft, computational fluid dynamics (CFD), inverse design, wing body, numerical optimization
