| Abstract: | This paper presents the airframe/scramjet integrated design method of hypersonic vehicle,in which we design lower surface configuration of airframe and get the Pareto front side through using one-dimensional flow formula to compute performance objectives,and adopting multi-objective genetic algorithms as the optimization method.The calculation results show that this design method can improve the matching level of airframe/scramjet integration greatly,and can give us a design project of high performance.As a method,it can be applied in the optimization design with more accurate flow model. |
