Research of airframe/scramjet integrated design of hypersonic vehicle

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.
