Multi-criteria design optimization of integrated three-dimensional supersonic inlets

Automated optimization by means of numerical simulation is a very promising technique now mainly used for research studies. However, its applications in an industrial context are not very common. This paper presents the optimization of a supersonic air intake in the context of the development of an actual air-breathing missile. Since this technique mostly relies on CFD, a description of the software capabilities is first given. Then the principles of automated optimization are introduced and the major families of optimization algorithms presented. The industrial loop is described and its use on the realistic and complex industrial problem illustrated. The results are very promising in terms of reduction of time and costs of design developments. 2001 by EADS Aerospatiale Matra Missiles and Rutgers University.
