Applying concurrent engineering on wing shape design with responsibility constraints

In this paper a concurrent engineering application to the wing design process of an aircraft manufacturer is presented. First, an overview of the disciplines and the conflicting sets of requirements the wing designer has to deal with is provided. Next, a rapid methodology to couple the aerodynamics and the wing box structural mechanics is presented. The methodology will allow the designer to rapidly retwist the wing to match a target load distribution related to top level aircraft requirements, and include flexibility effects at an early stage of the design. Results of the methods are shown to produce a satisfactory level of accuracy, for a vastly reduced cost, and the methodology proven as fit for purpose by interviews with wing designers. The approach is also discussed from a philosophical point of view, and cost issues, benefits, and limitations considered.
