| Abstract: | This paper presents a multi-objective shape optimization method for the conceptual design of reentry vehicles.The class function/shape function transformation technique is used to represent briefly the various shapes of the reentry vehicles with relatively few variables.The aerodynamic characteristics of the vehicles are predicted by an engineering method which accounts for the effects of real-gas flow across the oblique shock wave.The multi-objective evolutionary algorithm non-dominated sorting genetic alg... |
