Abstract
Grid fin is a space lifting surface formed by the external frame and internal web, which is of outstanding advantages in hypersonic state. Hypersonic aerodynamic characteristics analysis model of grid fin-body configuration is established based on surface element method considering the characteristics of hypersonic flow, the head shock wave and body upwash interference were taken into account as well. Surface element was built automatically according to grid fin-body configuration geometry feature. Grid fin-body configuration hypersonic aerodynamic characteristics were obtained and agreed well with numerical results. The deviation increases with angle of attack.
