Analysis of Flowfield around Surface Microstructure of Hypersonic Vehicle

摘要

In this article, the typical ablation surface microstructures of hypersonic vehicle are obtained by the surface roughness measurement. The viscous flowfields around this microstructure were analyzed with the advanced finite element method under assumption of laminar. An orderly microstructure will maintain through the flight of hypersonic vehicle according to the analysis of the flowfields near the wall and the small thrust produced by the microstructure can be applied in flight control of hypersonic vehicle.
