چکیده
Hypersonic vehicle has gained increasing attention due to its high cruise speed and long voyage. In this paper, an enhanced Sequential Approximate Optimization method is proposed for aerodynamic optimization of a hypersonic vehicle. method, constrained design experiment adopted generate the initial sampling set with adequate number feasible points. A field metamodel surrogate parameters distributions in flow obtained by simulation. hybrid combing radial basis functions polynomial chaos expansion applied construct good approximate performance. robust mesh morphing scheme based on developed high-quality meshes sequential scheme. The problem performed using framework satisfactory results are limited computational budgets. Results show that metamodel-enhanced possesses powerful performance promising prospects design.

Rapid Simultaneous Hypersonic Aerodynamic and Trajectory Optimization Using Variational Methods
Traditional multidisciplinary design optimization methodologies of hypersonic missions often employ population-based global searching methods that rely on shooting methods to perform trajectory optimization. In this investigation, a rapid simultaneous hypersonic aerodynamic and trajectory optimization methodology is constructed based on variational methods. This methodology is constructed from ...
متن کاملSequential Approximate Multiobjective Optimization Using Computational Intelligence
In many practical problems, in particular in engineering design, the function form of criteria is not given explicitly in terms of design variables. Given the value of design variables, under this circumstance, the value of objective functions is obtained by real/computational experiments such as structural analysis, fluidmechanic analysis, thermodynamic analysis, and so on. Usually, these expe...
