Abstract
The quasi-waverider configuration is an important configuration of hypersonic cruise vehicle (HCV), and the multi-objective optimization design to the airframe for quasi-waverider configuration can greatly improve the integrated performance of HCV. In this paper, multi-objective hybrid genetic algorithms was applied in the integrated optimization of airframe for the type of HCV by two strategies. The integrated performances include lift-to-drag, thrust-to-drag, trimming characteristic, radar cross section (RCS), and volume of body and stagnation temperature of nose and so on. When the population is convergent, the Pareto front side is got. In these Pareto solutions, we found some excellent body configurations, which have better integrated performances than basic configuration. Through the analysis to design results, the shortage of airframe/scramjet integration and the necessity of integrated optimization design were pointed out. In the Pareto front side, one optimal configuration has been chosen whose aerodynamic charecteristics has been validated by wind tunnel test.
