Abstract

A multipoint optimization approach is used to solve aerodynamic design problems encompassing a broad range of operating conditions. On-design and off-design operating conditions are represented as design points with corresponding objective and constraint functions. The use of a weighted integral as an objective function is demonstrated to improve aerodynamic performance over a range of on-design cruise conditions and also allows the designer to prioritize operating conditions based on mission requirements. Pareto fronts are presented as a useful tool in a multipoint design methodology enabling an understanding of trade-offs between competing design objectives which can aid the designer in improving the formulation of the design problem.
