Abstract
It is well known that a modern fighter should have high aerodynamic performance, i.e., high lift (C L) and low drag (C D), high C L/C D at subsonic speed and low drag at supersonic speed, etc. However, stealthy performance has also become one of the basic requirements to a modern fighter. So the task of a designer today is to shape the aircraft with not only the maximum aerodynamic efficiency but also a low observability. Up to now, reducing radar cross section (RCS) is the most important part of low observable technique for a flight vehicle. These requirements derive the development of multiobjective (MO)/multidisciplinary (MD) optimization. The goal of MO/MD optimization is to obtain one of the needed pareto solution at a minimum computing expense. A computational study of biobjective (BO) /bidisciplinary (BD) optimization of airfoils and wings is given in the present paper.
