A Based Response Surface Method Concurrent Subspace Optimization Of Antiship Missile

Multidisciplinary Design Optimization (MDO) is a design architecture developed since the last two decades, which is mainly focused on solving the design problems of large-scale complicated engineering systems. Because of its excellent computation characteristics, MDO has played an important role in the field of aeronautic & astronautic engineering design. Concurrent Subspace Optimization (CSSO), as a typical MDO method, is well suited to multidisciplinary design environment, especially large-scale distributed analysis problem. When used in multidisciplinary environment, CSSO has several advantages over standard optimization method: reduction of the information transfer; elimination of large iteration loop; allowance of the use of corresponding subspace optimizers in different disciplinary analysis; a parallel optimization architecture which is readily operable on a suite of heterogeneous equipments; more natural fit to the current organization structure found in most institutes of aerospace and aeronautic design; participation of the disciplinary experts to best deal with specific disciplinary models. This paper is mainly focused on CSSO method. And its application to the design optimization of antiship missile is realized satisfactorily.The major work in this paper includes:a) The development and mathematical framework of a based on Response Surface Method (RSM) CSSO are introduced and its feasibility is argued by two problems.b) Analysis models of aerodynamics, trajectory and propulsion system are established. Based on these models, the initial values for the design variables are chosen.c) The concurrent subspace optimization framework for antiship missile is set up. Based on this framework together with those disciplinary analysis models, the concurrent subspace optimization of antiship missile is finally realized.
