This paper approaches the question of multi-objective optimization for optimum shape design in aerodynamics on coupling the Adjoint method with implicit constraint and Nash Game strategy.The Game theory is a mathematical tool to describe and solve the problems under the conflict.The main content of the modern Game theory is non-cooperative game.In this paper,the game theory is applied to solving a conflicting problem of multi-objective optimum in aerodynamic design,in order to search a trade-off solution in these conflicting objectives.Finally,the design results suggest that this method is validated and efficient for aerodynamic shape optimization,furthermore,it can be used in distributed computing on multiple workstations.
