Aerodynamic Optimization Under a Range of Operating Conditions

Abstract

Conditions. This can be achieved through multipoint optimization. The desired performance objective and operating conditions must be spec- ified, and the resulting optimization problem must be solved in such a manner that the desired performance is achieved. Issues involved in formulating multipoint optimization problems are discussed. A technique is proposed for automatically choosing sampling points within the operating range and their weights in order to obtain the desired perfor- mance over the range of operating conditions. Examples are given involving lift-constrained drag minimization over a range of Mach numbers. Trade-os and their implications for the formulation of multipoint problems are presented and discussed.
