| Abstract: | Traditionally,aerodynamic shape optimization has focused on obtaining the best design given the requirements and flow conditions.However,the manufacturing accuracy of the optimal shape is depends on the available manufacturing technology and other factors,such as manufacturing cost.It is imperative that the performance of the optimal design is retained when the component shape differs from the optimal shape due to manufacturing tolerances and normal wear and tear.These requirements naturally lead to the ide... |
